Ridgway Reservoir during winter


Here’s the release from CPW:

This year marks the 25th anniversary of the construction of the Ridgway dam and the establishment of Ridgway State Park. A special event to recognize those who worked on the construction project is scheduled for the weekend of Aug. 8 at the park.

Did you work on the project? Or do you know someone who did? This includes former or current employees of the Bureau of Reclamation or other government agencies, construction workers, and municipal and county officials who assisted with the project. If so, please send your contact information via e-mail to: rhonda.palmer@state.co.us, or call her at 970-626-5822, ext. 11. You’ll be contacted about the event.

Planning for the Dallas Creek Project, as it is called formally by the BOR, began shortly after the end of World War II. Construction eventually started in 1978 and the reservoir filled completely for the first time in 1990. The dam stores water for agricultural, municipal and industrial uses for the Uncompahgre Valley in western Colorado.

One of Colorado’s premier recreational facilities, Ridgway State Park offers camping, hiking, bicycling, boating, fishing and swimming. More than 300,000 people visit the park every year.

Water Lines: Hydropower kicks off at nearby Ridgway Dam #ColoradoRiver

June 25, 2014
Ridgway Dam

Ridgway Dam

From the Glenwood Springs Post Independent (Hannah Holm):

When Ridgway Dam was constructed on the Uncompahgre River back in the 1970s and 1980s, hydropower was anticipated to be one of its uses — along with providing irrigation water, drinking water and flood control.

Mike Berry, general manager of Tri-County Water (company operating the dam), continues to look for opportunities to start generating hydropower since 2002.

It wasn’t until this month, however, this vision was finally realized.

In June, Tri-County Water officially commissioned a new eight-megawatt generating station powered by water flowing through the dam.

Finding a customer to buy the power at the right price was the key allowing the project to go forward.

The $18 million project is financed through the City of Aspen. The agreement includes payment of a premium for the power generated by Ridgeway Dam for a few years of the 20-year contract in exchange for better rates later.

Tri-County will also sell power to Tri-State Generation & Transmission and the Town of Telluride.

The power generated by Ridgway Dam will vary seasonally, with peak generation coinciding with large summer releases of water to downstream irrigators. The Grand Junction Sentinel reported last week the plant will produce a total of about 24,000 megawatt hours of electricity in an average year — enough to supply 2,500 average homes and eliminate 50 million pounds of carbon dioxide emissions.

The Ridgway Dam generating station was commissioned just one year after the completion of a 7.5-megawatt power generation project on the South Canal — carrying water from the Gunnison Tunnel near Montrose to the irrigators of the Uncompahgre Valley.

Both the Ridgway Dam and South Canal projects avoid the opposition previous hydropower projects faced because it’s installed on existing infrastructure and harvesting power from the regular operations of the facilities. As a result, irrigation deliveries are uninterrupted and no additional disruptions to river flows.

Interest in retrofitting existing water infrastructure to add power generation capability has surged in recent years. Both the State of Colorado and the federal government have made moves to support the trend with new laws to streamline the permitting process.

Finding customers for the power generated at affordable prices for construction is one of the key challenges faced by those interested in developing such facilities. Low prices for natural gas and the irregular supplies generated by such projects are complicating factors in working out power purchase agreements.

On the other side of the equation, renewable energy standards passed by Colorado and other states have created new opportunities.

From The Watch (Samantha Wright):

A decades-long quest to convert the power represented by the 84,600 acre feet of water pent up behind the dam into clean, green hydropower came to fruition at a commissioning ceremony hosted by Tri-County Water Conservancy District [June 6].

Tri-County’s new 8 megawatt hydroelectric plant will produce approximately 24,000 megawatt-hours of electricity in a typical water year, enough energy to supply about 2,500 homes, on average. The emissions reduction benefit from the new plant is equivalent to removing approximately 50 million pounds of carbon dioxide from the atmosphere (the same effect as taking about 4,400 cars off the road each year).

Federal officials including Larry Walkoviak, the Upper Colorado Regional Director of the Bureau of Reclamation, and U.S. Congressman Scott Tipton were on hand at the commissioning ceremony on Friday to praise the project’s merits.

But the folks who are really celebrating this historic moment are those who have steered the hydro project through choppy waters toward its completion including officials from Tri-County and the City of Aspen, which helped fund the project and is purchasing a significant portion of the energy it produces.

From The Grand Junction Daily Sentinel (Gary Harmon):

Green and grassy, Ridgway Dam looms high 15 miles southeast of Montrose, holding back Ridgway Reservoir. It’s flanked by a rocky ridge and U.S. Highway 550, with the Uncompahgre River bubbling up from the base of the dam to a prized stretch of trout water running through Ridgway State Park.

There is more to Ridgway Dam, though, than appearance.

“It’s not just a beautiful pile of dirt,” said Ion Spor, who has managed the dam for decades for the Tri-County Water Conservancy District.

Ridgway Dam is now generating electricity, eight megawatts worth during the height of the water year.

Tri-County — referring to Montrose, Delta and Ouray counties — commissioned the generating station earlier this month, marking the culmination of a project that was anticipated well before construction of Ridgway Dam, begun in 1978 and completed in 1987. Ridgway Reservoir filled in 1990.

The dam was built with hydropower in mind. Pipes were run through the dam in anticipation of someday being hooked up to generators, said Mike Berry, Tri-County general manager.

After years of debate, Tri-County opted to move ahead with the $18 million project. It reached agreements with Aspen, Telluride and Tri-State Generation and Transmission to get enough money for the project.

The station also generates power for the Delta-Montrose Electric Association and the San Miguel Power Association.

As part of its agreement to purchase power, Aspen is buying renewable-energy credits created by the project during winter months. Telluride is purchasing the credits that are created by the project during summer months.

Renewable-energy credits represent the added value and environmental benefits of the electricity produced by the generating station.

Tri-County will use the revenues generated from the sale of the electricity and renewable-energy credits to repay loans on the project for the first 30 years and then to offset its operating expenses, Berry said.

Tri-County’s generating station contains two turbines and generators.

The smaller is a 0.8-megawatt system, which will operate solo during the winter when flows are low, in the range of 30 to 60 cubic feet per second. The larger, 7.2-megawatt system will operate on flows of 500 cfs during the summer.

Both generators are in a powerhouse at the base of the dam.

The plant will produce about 24,000 megawatt-hours of electricity in an average water year, enough energy to supply about 2,500 average homes and eliminate the equivalent of 50 million pounds of carbon dioxide emissions.

Now, Tri-County needs one thing to make the system work, Berry said.

“We’re counting on Mother Nature,” Berry said, “To bless us with enough water to repay the notes.”

Hydropower used to replace flood irrigation and to lessen ag runoff and salinity

June 25, 2014

Hydropower sprinkler system via Homelink Magazine

From ColoradoBiz Magazine (Allen Best):

And now come new efforts across Colorado to further yoke the power of falling water. One such example is near Yampa, a town between Vail and Steamboat Springs. The site is just a few miles from where the Bear River takes a sharp turn and becomes the Yampa River. On his ranch, Gary Clyncke decided three years ago to use the 126-foot drop in elevation of his irrigation water to power a new center-pivot irrigation system.

Clyncke’s hydro-mechanical center-pivot doesn’t produce electricity. It does, however, preclude the need for stringing up power lines to operate the center-pivot sprinklers. The sprinkling system, in turn, saves water — which is worth money. The 90 acres were previously irrigated with flood irrigation from ditches spread across the field of timothy, brome and clover several inches thick. Center-pivot irrigation requires just one-sixth the water.

That savings motivated Clyncke to invest in center-pivot. This hydro-mechanical system cost $13,000, of which $6,000 came from the Natural Resources Conservation Service, a federal agency. That left Clyncke a cost of $7,000. Payback on that investment is achieved in three years.

Federal aid is motivation, at least in part, because of concerns about salinity. When large volumes of water are applied to fields in flood irrigation, the water picks up salts that are then returned to creeks and then rivers. It’s a major problem on the Western Slope, where water can be used two times for flood irrigation before it enters Utah. Downstream in California’s Imperial Valley, an important source of food for the nation, some fields have become so salty they have been abandoned.

One of the most saline areas is in the Uncompahgre Valley, where Delta, Montrose and Paonia are located. An ancient sea left salts and the element of selenium in unusually large quantities in the Mancos shale. Both are harmful to endangered fish downstream in the Colorado River. “Anything that you can do that helps with salinity also helps with selenium, and vice versa,” says “Dev” Carey, manager of the Delta Conservation District.

Saving money is a strong argument by itself. Farmers spend an average of $33,000 each year on electricity, more than half of that to power irrigation pumps, according to the Colorado Energy Office. Using hydropower to operate these pumps doesn’t work everywhere. Farms near Sterling, for example, tend toward flatness. Still, the state agency estimates Colorado has untapped capacity in pressurized irrigation systems to deliver 30 megawatts in direct production of electricity or avoided electricity. To put that into context, it’s enough electricity for 12,125 homes, says Kurt Johnson, president of the Colorado Small Hydro Association.

More potential exists in irrigation ditches. Not just any irrigation ditch will do. It must have flows of more than 100 cubic feet per second, a relatively large volume. And there must be drops of at least 150 feet. When falls of that steepness occur, various devices are used to contain the force.

One such canal is located east of Montrose, where water from the Gunnison River is diverted through a tunnel that emerges near U.S. Highway 50. From there, the water flows through South Canal toward the head of the Uncompahgre Valley. In 2012, the Delta-Montrose Electric Association completed a project that had been talked about for more than 100 years. The two powerhouses generate electricity equal to what is needed for 3,000 homes.

In nearby Delta County, the state has identified nine sites on irrigation ditches where it would be economical to install small hydro systems, collectively producing 0.8 megawatts. That’s given current prices of electricity. Should electricity prices go up, as they have steadily, more potential would exist near Delta and many other locations.

Runoff/snowpack news: Good year to fill storage — if we had it to fill

June 10, 2014
Northern Integrated Supply Project via The Denver Post

Northern Integrated Supply Project via The Denver Post

From CBS Denver:

Flooding along the Cache La Poudre River damaged nearly two dozen homes and businesses in Greeley last week, and according to officials at the Northern Colorado Water Conservancy District, the Poudre River does not have any dams or reservoirs specifically for flood control. But there is an effort underway to change that.

The Poudre River is full of melted snow — so much so right now that levels are well above average in Larimer and Weld counties, spilling over banks, and flooding homes and businesses.

“We could fill a reservoir in a year like this,” Brian Werner with the Northern Colorado’s Water Conservancy District said.

He points out farmers’ irrigation dams inside the Poudre Canyon, but says water cannot be diverted to those to prevent flooding. He says there is no reservoir along the river because the idea was unpopular in the past.

“I think the general public is more aware when they see these flows and saying, ‘Boy, couldn’t we just store a little bit of that?’ Which is what this proposal does,” Werner said.

Northern Water wants to build two reservoirs off stream that could store water during high flow times. Planners estimate the project would cost $500 million, including $40 million to re-route Highway 287 to make room for Glade Reservoir, and build a smaller one north of Greeley…

But the federal approval process is moving slowly.

“We’ve been working on this in some form for over 20 years, taking some of the flood flows here on the Poudre and storing it,” Werner said.

They do expect to get some news on the status of studies being conducted on the project by the end of this year. It’s unlikely building would start before 2018.

From the Fort Collins Coloradoan (Ryan Maye Handy):

Several of the reservoirs that feed Northern Colorado are full, or approaching overfull, said Brian Werner, a spokesman for the Northern Colorado Water Conservancy District, which helps manage the reservoirs. Carter Lake, southwest of Loveland, is full, and Lake Granby near Rocky Mountain National Park is about to overflow, Werner added.

“We wouldn’t have guessed that in a million years a year ago,” Werner said Tuesday. Only a month ago, it was fifty-fifty if the reservoir would spill. “Now it looks like it will spill.”

Horsetooth is just 2 feet shy of being full, the highest the reservoir has been in late May and early June in the past six years.

The reservoir can hold enough to submerge 156,735 football fields in a foot of water. As of June 3, Horsetooth was holding 154,480 acre-feet of water, putting it around 98.5 percent full, said Zach Allen, a spokesman for Northern Water.

But what happens if Horsetooth does get full? The answer, Werner said, is basically “nothing.”

“We can control all the inflows to Horsetooth,” he said. Flatiron Reservoir and the Big Thompson River feed Horsetooth, and Northern Water controls all the outflows and inflows to the reservoir; Horsetooth’s water level can’t get higher than Northern Water wants it to, Werner said…

Lake Granby, on the other hand, is fed with snowmelt straight from the mountains. It’s levels are uncontrollable, and it could spill over any day now, Werner said.

“You can’t control what nature is going to do” with Granby, he added…

Northern Water for years has pursued an expansion of its water storage capacity to take advantage of plentiful water years. The Northern Integrated Supply Project would build a reservoir larger than Horsetooth northwest of Fort Collins. The proposal has drawn opposition from environmental groups and is in a yearslong federal review of its potential environmental impacts expected to be released late this year…

Much of Northern Colorado’s snowpack, around 200 percent of normal levels after an early May snow, has yet to melt, which brings the potential for much more water to come down from the mountains in the coming weeks.

From email from Reclamation (Kara Lamb):

We have seen the water level at Green Mountain Reservoir rise to the spillway gates as snow melt runoff inflows continue to come into the reservoir. As a result, we were able to increase the release from the dam to the Lower Blue River by 300 cfs today [June 9], using the spillway.

We are now releasing 1800 cfs to the Lower Blue.

From email from Reclamation (Kara Lamb):

The weekend went pretty smoothly for runoff here on the east slope of the Colorado-Big Thompson Project. Thunderstorms boosted runoff to the Big Thompson River slightly with inflow into Lake Estes peaking early this morning around 721 cfs. But this is still a downward trend.

As a result, outflow through Olympus Dam to the Big Thompson Canyon dropped today down to about 125 cfs. As we move into the rest of the week, visitors to and residents of the canyon will continue to see nightly flows rise with snow runoff, enhanced some by rain runoff, just as they have seen for the past week.

Deliveries to the canal that feeds Horsetooth Reservoir have brought Horsetooth back up to full. Its water level elevation has been fluctuating within the top foot of its storage between 5429 and 5430 feet. With it back up near 5430, we have curtailed the canal to Horsetooth and increased the return of Big Thompson River water to the canyon at the canyon mouth using the concrete chute. By 5 p.m. this evening the chute should be running around 300 cfs.

The drop off in snowmelt runoff inflows will allow us to begin bringing some Colorado-Big Thompson Project West Slope water over again using the Alva B. Adams Tunnel. We anticipate the tunnel coming on mid-week and importing somewhere between 200-250 cfs.

Once the tunnel comes back on, we will also turn the pump to Carter Lake back on, probably on Wednesday of this week. Carter’s water level elevation dropped slightly during runoff operations. It is around 95% full. Now that Horsetooth is basically full, Carter will receive the C-BT water. Turning the pump back on to Carter means residents around and visitors to the reservoir will see it fill for a second time this season.

Pinewood Reservoir, between Lake Estes and Carter Lake, is seeing a more typical start to its summer season. It continues to draft and refill with power generation as it usually does this time of year. This is also true for Flatiron Reservoir, just below Carter Lake and the Flatiron Powerplant. Both are expected to continue operating this way through June.

That is the plan we anticipate the East Slope of the C-BT to follow the rest of this week, June 9-13. We will post information if there is a major change; but as it stands now, I do not plan on sending an update again until next Monday. The state’s gage page is always available for those wishing to continue watching the water on a daily basis.

From The Crested Butte News (Toni Todd):

Word on the street this spring was that Blue Mesa Reservoir would be bursting at its banks this summer. Predictions were based on official and unofficial reports of above-normal river flows. However, a 2012 Environmental Impact Statement (EIS) has changed how local dams are operated in wet years, in deference to endangered fish species downstream. This new operational protocol will preclude the reservoir from filling this year.

“The reservoir is now only scheduled to reach a maximum storage of around 80 percent capacity in 2014,” said Upper Gunnison River District manager Frank Kugel. The U.S. Bureau of Reclamation (BOR) began blasting water through Blue Mesa Dam last week, with simultaneous releases happening at Morrow Point and Crystal Reservoirs, a trifecta of water storage and management that makes up what’s known as the Aspinall Unit.

The Record of Decision (ROD) states, “The EIS modifies the operations of the Aspinall Unit to provide sufficient releases of water at times, quantities, and duration necessary to avoid jeopardy to endangered fish species and adverse modification of their designated critical habitat while maintaining and continuing to meet authorized purposes of the Aspinall Unit.”

Given this new norm of operations adapted by the bureau during wet years, will Blue Mesa ever fill again?

“That’s a valid question, since the reservoir often does not fill in dry years due to lack of supply, and now with the Aspinall EIS, it will have trouble filling in wet years,” said Kugel.

“We all signed onto this because we agreed it’s important to save these fish,” said Colorado Fish and Wildlife Aquatic Species coordinator Harry Crocket.

According to the BOR’s website, an update written by hydraulic engineer Paul Davidson, unregulated inflow to Blue Mesa is 126 percent of normal this year, April through July. That’s 850,000 acre-feet of water entering the lake during the runoff months. “This sets the senior Black Canyon Water Right call for a one-day spring peak flow of 6,400 cfs, the Aspinall 2012 ROD target at a 10-day peak flow of 14,350 cfs… Reclamation plans to operate the Aspinall Unit to meet both the water right and ROD recommendations,” said Davidson.

The Colorado pike minnow, bonytail chub, humpback chub and razorback sucker are the fish that stand to benefit. The big flows are expected to improve the fishes’ critical habitat, at a time when the fish will be looking to spawn. Water will inundate otherwise shallow or dry riverbank areas, creating calm, sheltered spots for hatchlings, and heavy flows will wash the larvae into those areas.

The Gunnison River, said Crocket, was “mostly omitted” from the EIS as critical habitat. However, he said, “Historically, it was home to at least a couple of these species.”

“It’s a highly migratory fish,” Crocket said of the Colorado pike minnow. “It’s adapted to this big river system.”

It’s a system irrefutably changed by humans. Critical habitat for the Colorado pike minnow includes 1,123.6 miles of river, to include stretches of the Green, Yampa and White rivers, from Rifle to Glen Canyon, and the Yampa River to its confluence with the Colorado River.

“They [US Fish and Wildlife] did designate critical habitat [from the mouth of the Gunnison] to the Uncompahgre confluence [at Delta],” Crocket said.

The Colorado pike minnow called the Gunnison River home through the 1960s. “After that,” said Crocket, “it blinked out. It’s not been possible for it to be re-colonized.” A new fish passage at the Redlands structure, two miles upriver from the Gunnison-Colorado River confluence at Grand Junction, allows fish to make their way around the barrier and upstream, marking the first time in more than 100 years for those downstream fish to gain passage to the Gunnison.

Meanwhile, upstream, a form of collateral damage resulting from the big water releases at Blue Mesa worries Fish and Wildlife personnel. The number of fish sucked into and blown out through the dam is staggering. The technical term for this is entrainment.
“Bigger water years mean more water through the dam, and more fish entrained,” said Gunnison area Colorado Fish and Wildlife aquatic biologist Dan Brauch. “Certainly, loss of kokanee with those releases is a concern.”

From the Vail Daily (Randy Wyrick):

Water levels and snowpack are 121 percent of normal, with as much as 40 percent yet to melt at some higher elevation areas, according to Snotel data…

Snow water equivalent at the Fremont Pass Snotel site, the headwaters of the Eagle River, had 15.1 inches of snow water equivalent on Friday morning still to melt and run into the river. It hit 17 inches on March 18 and kept piling up until May 17 when it peaked at 25.6 inches. It usually doesn’t melt out until June 18, Johnson said.

Streamflow on the Eagle River in Avon may have peaked on May 30, when the daily mean discharge was 4,110 cubic feet per second, which was 249 percent of median for that date. Thursday’s daily mean discharge was 3,650 cfs, 197 percent of normal for Wednesday.

Gore Creek in Lionshead may have peaked June 4.

“Having 20 to 40 percent of the total snowpack remaining in higher elevations in the Colorado Basin is good overall. It should help sustain streamflows through the month,” [Diane Johnson] said…

Copper Mountain still has 4.1 inches of snow water equivalent. That would normally be melted out by now, Johnson said…

Reservoir storage in the state is running 95 percent of normal and 62 percent of capacity. That, however, depends on where you are.


Video: Ridgway Dam hydro project commissioned — Telluride Daily Planet

Ridgway Dam

Ridgway Dam


From the Telluride Daily Planet (Heather Sackett):

On Friday, the Tri-County Water Conservancy District officially commissioned a new hydropower project at the Ridgway Dam.

The celebratory event included refreshments, tours of the powerhouse and a history of the project. The 8-megawatt, two-turbine, two-generator plant will produce about 24,000 megawatt-hours of electricity in an average water year, enough to power 2,500 homes a year with all their electricity needs. Construction on the Uncompahgre River project began in November 2012.

The City of Aspen and Tri-State Generation and Transmission are purchasing the power and Aspen is also buying the Renewable Energy Credits created by the project during the winter months. The Town of Telluride won a bid to purchase the RECs for June through September for $48,000. RECs are market-based instruments that convey the environmental value of renewable energy between buyers and sellers. Each REC provides proof that 1 megawatt-hour of renewable energy has been generated.

Buying the RECs was a step toward achieving the Telluride Renewed Challenge, an attempt to reduce greenhouse gas emissions to 20 percent below 2005 levels by 2020 and for 100 percent of the community’s electricity to come from renewable sources by 2020. Telluride Mayor Stu Fraser says though those aims might now prove too lofty, the town still likes to lead by example…

According to a press release from the Colorado Small Hydro Association, the emissions reduction benefit from the new plant is equivalent to removing approximately 50 million pounds of carbon dioxide from the atmosphere or about 4,400 cars from the road each year. Colorado Small Hydro Association President Kurt Johnson, of Ophir, said the Ridgway Dam hydro project is a great example of new hydro power on an existing dam.

“Only about 3 percent of the nation’s dams currently include hydropower,” Johnson said in a press release. “There is an enormous untapped opportunity to generate new clean energy using existing infrastructure.”

General Manager of the Tri-County Water Conservancy District Mike Berry said he is excited the project is complete and that it provided many local jobs during its construction.

“I’m glad we are coming to the end of it and the generator will be spinning for the rest of my life I hope,” Berry said.

Aspinall Unit update: The Uncompahgre Water Users are calling for water #ColoradoRiver

April 8, 2014
Gunnison Tunnel via the National Park Service

Gunnison Tunnel via the National Park Service

From email from Reclamation (Erik Knight):

The Uncompahgre Valley Water Users Association (UVWUA) will be diverting an additional 100 cfs through the Gunnison Tunnel tomorrow morning Tuesday, April 8th. At the same time, releases from Crystal Dam will also be increased by 100 cfs, from 750 cfs to 850 cfs. After this change, the total flow through the Gunnison Tunnel should be about 400 cfs, which should leave about 450 to 500 cfs in the Gunnison River downstream of the tunnel.


The Tri-County Water Conservation District is bringing on two hydroelectric generation stations at Ridgway Dam

February 24, 2014
Ridgway Dam via the USBR

Ridgway Dam via the USBR

From The Watch (Samantha Wright):

Over the past year and a half, two hydropower generators have sprung up at the foot of the dam: a smaller, 800kV generator that should run efficiently on the low, 30-60 cubic-feet-per-second flows in winter, and a larger, 7.2 megawatt generator to run on summertime release levels.

Next week, on Feb. 24 or 25, the smaller of these two units will be turned on and start producing a steady stream of green electricity, said Mike Berry of Tri-County Water Conservation District, the entity that manages the Ridgway dam and is building the power-generating facility at its base.

The big generator should be ready for testing by April or so, Berry said. When the project goes fully online later this spring or early summer, it will have a total plant capacity of 8 Megawatts – enough renewable power to run 2,250 homes and take the equivalent, in greenhouse gases, of 4,400 cars off the road.

Both units will operate during high reservoir releases in the summer, and only the smaller unit will operate during lower wintertime releases.

Tri-State Generation and Transmission, the wholesale electric supplier for San Miguel Power Association and the Delta-Montrose Electric Association, has built two short transmission lines at the hydropower plant. One will connect to the existing 115kV line running alongside the highway, and another will connect with the generating station.

Power generation will have to be carefully calibrated in order to maintain historic release patterns at the dam – one of the requirements of the Bureau of Reclamation’s final Environmental Assessment of the project – while maintaining healthy lake levels and maximizing power production.

In times of drought, the water rights of downstream irrigators, industries and municipalities will trump power generation…

Power generated at the hydro plant will be sold to two entities: Tri-State, and the City of Aspen. Tri-County WCD first started discussing a partnership with the City of Aspen in 2002. Eventually, this partnership evolved into a Power Purchase Agreement, or PPA.

In an agreement inked in 2010, Aspen agreed to purchase the wintertime output from the hydropower project, from Oct. 1 through May 31, for 20 years, to help further its goal of powering the city with purely renewable energy. Tri-State has agreed to purchase, for 10 years, the higher summertime output.

If projections hold up, about 10,000 MWh worth of energy will be “transferred” to the City of Aspen through the PPA annually (although it is doubtful that any of the actual electrons flowing into the grid from the new hydropower plant will travel that far). This amount is not set in concrete – Berry emphasized that there will be annual fluctuations in the amount of power that is delivered to Aspen, depending on a number of factors including whether it is a wet or a dry year, the timing of the spring runoff, and the demands of downstream water rights holders.

Tri-County WCD has secured $15 million in financing for the project – including a $13 million loan from the Colorado Water Conservation Board, and a $2 million loan from Colorado Water Resources and Power Development Authority – and has sunk an additional $3 million of its own money into the project…

As the new hydropower plant at Ridgway Reservoir prepares to go online, legislation has been introduced at the state capitol to help streamline development of smaller hydropower projects throughout Colorado.

Last week, the Colorado House of Representatives overwhelmingly passed HB14-1030 by a vote of 62-3. The bipartisan legislation complements the recent streamlining of federal permitting requirements for small hydro through the Hydropower Regulatory Efficiency Act.

HB14-1030 was introduced in the House by Reps. Mitsch, Bush and Coram. Senator sponsorship includes Senators Schwartz and Roberts as well as Hodge.

In essence, the bill “makes it possible to simultaneously complete federal and state review at the same time,” said Kurt Johnson, the president of the Colorado Small Hydro Association. It also seeks to streamline the electrical inspection process for small hydro, using precedents set in the small wind industry decades ago.

The Senate Agriculture, Natural Resources and Energy Committee will hold a hearing on the pending legislation on Feb. 27.

The Ridgway Town Council approves bumping storage in Lake Otonowanda to 600 acre-feet

February 19, 2014

From The Watch (Samantha Wright):

Located in Ouray County, about three miles south of Ridgway off of County Road 5, Lake O has been the Town of Ridgway’s primary municipal water source for nearly 100 years. The man-made lake is filled with water diverted into a natural basin via the Ridgway Ditch.

The Lake Otonowanda Rehabilitation Project will allow the town to exercise its full decreed storage right there by improving the lake’s capacity sixfold, from 100 to 600 acre feet, while restoring historic tunnel outlet works, which collapsed decades ago, to allow water to flow from the lake to town without having to be pumped.

The project is split into two phases, addressing tunnel restoration and lake excavation. Town officials had hoped to get started on the tunnel restoration phase last fall, but received only one response to a Request for Proposals issued in September 2013.

Hoping to attract more bidders, council and town staff agreed to broaden the scope of the contract to encompass both the tunnel restoration phase and lake excavation phase in a single package, and put the project out to bid in January.

This time around, there was a healthy response from contractors, with Town Manager Jen Coates reporting that over 30 people attended the project’s pre-bid meeting on Jan. 30; five of those companies went on to actually bid on the contract, with bids ranging from $1.4 to $1.9 million. The town budgeted up to $2 million for the construction project (bonding requirements put many smaller-scale local contractors out of the running, Coates said).

The Colorado Water Conservation Board awarded a $1.2 million grant/loan package to the Town of Ridgway last fall to help finance the Lake O project. In late January, the town applied to the Colorado River District for additional grant funds to cover a portion of the project construction.

Ridgway is embarking on a rehabilitation project for Lake Otonowanda

September 26, 2013

Lake Otonowanda — photo / Applegate Group

From The Watch (Samantha Wright):

The $2.4 million Lake Otonowanda Rehabilitation Project will allow the town to exercise its full decreed storage right by improving the lake’s capacity from 100 to 600 acre feet, while restoring the tunnel outlet near the reservoir to make the delivery system more efficient.

The town’s municipal water right on Lake O predates the Colorado River Compact, a 1922 deal made by seven U.S. states in the basin of the Colorado River in the American Southwest, which to this day governs the allocation of the water rights to the river’s water.

Currently, due to Lake O’s modest size and declining condition, the Ridgway stores only a fraction of the water to which it is legally entitled; the renovation will allow the town to maximize Lake O’s historic adjudicated capacity. Stored water will supply the town when its flow rights are out of priority, ensuring enough water for most anticipated situations, even during drought years, and accommodating growth well into the future.

When the renovation is complete, the town will be able to supply water to the community for a minimum four-month period in a drought event, compared to its current storage capacity of only 10‐14 days’ worth of water.

The rehabilitation project got the big green light earlier this month, when the Town of Ridgway finalized a $1.2 million grant/loan package with the Colorado Water Conservation Board that will contribute significantly toward financing the project…

Arguably among the most scenic municipal reservoirs in the nation, Lake O is located about three miles south of Ridgway off of County Road 5, in an alpine meadow encircled by ponderosa forests and pristine views of the Cimarrons and Sneffels mountain ranges. It is the town’s primary municipal water source; the town also holds junior flow rights on Beaver Creek and Cottonwood Creek/Happy Hollow that are more vulnerable to calls. Generally, the lake provides enough water for the town’s needs (with an average of 280 acre feet diverted each year), but in the drought of 2002, all of Ridgway’s water rights were called by downstream senior water rights holders. The state water engineer subsequently put the town on notice to shore up water rights and storage strategies to prevent this situation from happening again.

New federal hydroelectric permitting laws would have helped Ouray with their project

September 7, 2013

ouray

Here’s a report from Allen Best writing for The Mountain Town News. Click through and read the whole thing. Here’s an excerpt:

[Ouray] Mayor Bob Risch wishes that the two new federal laws signed by President Barack Obama in August had been adopted before he set out to get his project approved.

Those two new laws simplify the federal government’s process for small hydroelectric projects involving pre-existing infrastructure. Promoters say the laws will make it easier to harness the power of flowing water in existing irrigation canals, small dams, and even municipal water lines. Neither of the new laws will result in new dams or diversions. They apply only to existing infrastructure and to installations of 5 megawatts or less.

The previous process was cumbersome. “It was unbelievable,” says Risch, of requirements for the Federal Energy Regulatory Commission permit. “They sent you a list of all the steps you have to go through. For example, it included a list of 55 organizations to which we had to send letters, informing them that we were going to start this process and invite comment from them.”

Aspinall Unit operations update: 550 cfs in Black Canyon

August 3, 2013

fogfilledblackcanyonofthegunnisonnps.jpg

From email from Reclamation (Erik Knight):

Due to the continuance of precipitation throughout the Gunnison River basin, flows in the lower Gunnison River, as measured at the Whitewater gage, have remained above the Aspinall Unit ROD baseflow target of 890 cfs. Scattered rainfall is forecast to occur over the basin during the next week, which will hopefully keep streamflows at or above their current levels.

Therefore, in order to conserve some storage in the Aspinall Unit, releases from Crystal Dam shall be decreased by 50 cfs (from 1,600 cfs to 1,550 cfs) at 8:00 am, Saturday, August 3rd. This will bring flows in the Gunnison River through the Black Canyon down to around 550 cfs.


Ouray: The city is trying to bolster its water rights to protect against a downstream call

June 27, 2013

ouray.jpg

From The Watch (Samantha Wright):

Thus the City of Ouray has been forever saddled with junior water rights compared to thirsty downstream irrigators, who are more and more likely to place a call on the city’s water supply as that water becomes ever scarcer in future years. This is the basic problem which the city seeks to resolve.

CDWR conducts tabulations of water rights throughout its various districts every two years. Water rights holders have one year from the time of the tabulation to object to a particular determination. The last tabulation of water rights affecting the City of Ouray took place in 2012, and the next one occurs in 2014.

The City of Ouray, through [City Attorney Kathryn Sellars], intends to file an official objection to the CDWR’s 2012 tabulation which enabled the M&D Canal to make a call on the city’s water supply last year.

In a position paper sent to to Division 4 Water Engineer Bob Hurford on June 13 outlining this objection, Sellars related the complicated history of water adjudication in Colorado and exposed special circumstances which, she argued, underline several flaws in the system when applied to Ouray.

Central to her argument is the so-called “subordination clause” in the first general adjudication decree in Division 4 in 1888 which “subordinates” agricultural water uses to so-called domestic water use but has been interpreted narrowly so as not to equate “domestic” with modern-day municipal water use…

“We don’t have the authority to tabulate a water right in the way the City of Ouray is asking,” [Jason Ullman, Assistant Division Engineer for CDWR’s Division 4] argued. “We have told them we would not oppose them if they filed with the water court to request that the seniority of water rights be clarified, and see what the water court judge says. They really need to take the matter to someone who has the authority to direct us to retabulate.”

CDWR’s research has not produced any other examples of other Colorado municipalities in the same situation as Ouray.

“It’s just the way the priority system was developed in Colorado,” Ullman said. “They couldn’t foresee this problem back then. It’s worked well for over 100 years, but there are some quirks in the system. The point is, we would not file an opposition to their request for retabulation, but the court needs to give its blessing to that. Because there is no other municipality in this situation.”

Aspinall Unit operations update: 700 cfs in the Black Canyon

June 25, 2013

crystaldamspill052009.jpg

Even with the recent increase in releases from the Aspinall Unit, the forecast for flows on the lower Gunnison River continues to decline. Without additional water, flows at the Whitewater gage are again expected to approach the 900 cfs baseflow target by this weekend.

In order to meet the environmental commitments set forth in the Aspinall ROD, releases from Crystal Dam shall be increased again, starting at 8:00 am on Wednesday, June 26, by 100 cfs (from 1,600 cfs to 1,700 cfs). This will increase flows in the Gunnison River through the Black Canyon to around 700 cfs. At this level, flows in the canyon will be above the Black Canyon Water Right peak flow target of 685 cfs. Flows through the canyon are expected to remain at this level for the foreseeable future.

From email from Reclamation (Erik Knight):

The forecast for flows on the lower Gunnison River continues to decline as the last remaining snow melts away. Even with the additional water released from the Aspinall Unit yesterday, it appears that flows on the Gunnison River as measured at the Whitewater gage will again recede towards the 900 cfs baseflow target by next week.

In order to meet the environmental commitments set forth in the Aspinall ROD, releases from Crystal Dam shall be increased again, starting at 8:00 am on Sunday, June 23, by 100 cfs (from 1,500 cfs to 1,600 cfs). This will increase flows in the Gunnison River through the Black Canyon to around 600 cfs

Aspinall Unit operations update: The Black Canyon Water Right one day peak flow target is 685 cfs #COdrought

May 31, 2013

aspinallunit.jpg

From email from Reclamation (Dan Crabtree)

Based on the May 1st April-through-July runoff forecast of 335,000 ac-ft for Blue Mesa Reservoir, the Black Canyon Water Right one day peak flow target is 685 cfs. Today’s flow through the Black Canyon is 300 cfs.

Due to the dry conditions and low Blue Mesa Reservoir content, the Whitewater baseflow target for June and July is 900 cfs. Current flows at Whitewater are around 1600 cfs. As tributary flows to the Gunnison diminish, and Whitewater flows approach 900 cfs, Reclamation will increase releases to attempt to maintain the target at Whitewater. We will provide as much advanced notice as possible regarding these release changes. We anticipate this operation will allow the Black Canyon one day peak target to be met sometime in the latter part of June, however, if insufficient, we intend to supplement releases with additional power releases as necessary to meet the target. We will keep you updated as things progress.

Say hello to the Ouray County Water Users Association

May 17, 2013

ouray.jpg

From The Watch (Samantha Wright):

Irrigators and other upper Uncompahgre River water users took preliminary steps last week to form a new organization which can act as a unified voice for various Ouray County water users in local, regional and statewide water use negotiations.

Ridgway attorney Andy Mueller, a senior partner at the Tisdel Law Firm in Ouray, led the discussion, which occurred last Thursday, May 9 at the Ouray County Land Use building, with about 30 water users and other interested parties in attendance.

Mueller is a member of the Colorado River District Board of Directors representing Ouray County, and has extensive water law experience. He expressed growing concern that as water becomes ever scarcer throughout the West, Ouray County water users still do not have an organized entity through which to assert their collective interest.

This puts them at a distinct disadvantage compared to entities such as the Uncompahgre Valley Water Users Association, Tri-County Water and the Upper Gunnison Water Conservancy District, “all of whom are very organized and very well versed in water administration and protecting their own rights and how they can best be served,” Mueller observed. “I wouldn’t suggest by any means that these folks are enemies, but just like anybody else, they are not necessarily there to look out for us. I think that’s our job as water users.”[...]

The association would take the form of a nonprofit corporation whose members use water from the Upper Uncompahgre River for any number of beneficial uses that are recognized by the state constitution. The entity would be self-governed and independent of county government. And, Mueller stressed, the organization first and foremost would respect the ownership and control of water rights as utilized within Colorado’s prior appropriation system – the “first in time, first in right” doctrine which in times of water shortage, permits a senior right to place a “call” on a stream to obtain a full supply. “This is not an effort to subvert water appropriation,” Mueller said. “It’s more to understand it and work within that system to the benefit of the water users.”[...]

The group could also focus on flushing out the “big picture” of water usage in the county, studying when and where shortages occur, and focusing on various solutions to address those shortages. Ultimately, the association could propose the formation of a new Water Conservancy District, the formation and funding of which would need to be put to a vote in Ouray County. Such an entity would have the authority to construct and acquire upstream reservoirs for county-wide water rights augmentation purposes that could be operated for the benefit of the county’s municipalities and irrigators alike, as well as for other water users, Mueller said…

A stakeholders group comprised of local ranchers Daris Jutten, Ken Lipton, Jack Flowers and Ken Orvis, and representatives from the Town of Ridgway and the City of Ouray, agreed to meet again in the near future to further explore the concept of forming a Ouray County Water Users Association. The next community-wide meeting on the topic is tentatively scheduled for Thursday, June 13 at 7 p.m. at the County Land Use building north of Ridgway.

Aspinall Unit operations update: Diversions through the Gunnison Tunnel bumped to 600 cfs #ColoradoRiver

April 11, 2013

fogfilledblackcanyonofthegunnisonnps.jpg

From email from Reclamation (Erik Knight):

A recent flow measurement by the USGS has shown us that the Gunnison River below the Gunnison Tunnel is currently running around 375 cfs. The Uncompahgre Valley Water Users could use more water to keep up with irrigation demands. Therefore, tomorrow morning, April 11th, diversions to the Gunnison Tunnel will increase by 75 cfs or so, leaving 300 cfs in the Gunnison River below the Gunnison Tunnel. There will be no change to Crystal releases. After this increase in diversion, flow in the Gunnison Tunnel should be around 600 cfs.

Grand Junction: Aspinall Unit operations meeting April 25

April 8, 2013

gunnisontunnelnps.jpg

From email from Reclamation (Dan Crabtree):

The Uncompahgre Valley Water Users began diversions through the Gunnison Tunnel [last] week. Consequently, releases from Crystal Dam are about 750 cfs, the Tunnel is currently diverting about 400 cfs, with the balance through the Canyon/Gorge. Reclamation plans to continue to operate in accordance with the Aspinall Operations Record of Decision and to allow the Black Canyon Water Right to be met. As the Tunnel increases diversions over the next few weeks, mild fluctuations in the Gunnison River in the Canyon/Gorge may occur.

The April 1 Blue Mesa forecast for unregulated April through July runoff is 315,000 ac-ft which is 47% of average. The April Operations Meeting will be held on April 25th in Reclamation’s Western Colorado Area Office, 2764 Compass Drive Suite 106, beginning at 1:00 p.m.

San Juans: Just two dust on snow events so far this winter #codrought

March 11, 2013

dustonsnowsanjuans.jpg

From The Telluride Daily Planet (Collin McRann):

One of the leading local climate research entities in the state is the Silverton Center for Snow and Avalanche Studies, which has been conducting research on local precipitation and snowpack for more than a decade. Over the years, the center has accumulated reams of data about the snowpack, and on Friday a researcher presented some of the center’s findings at the monthly EcoAction Roundtable at the Wilkinson Public Library to a crowd of more than 15 people…

Though a lot of climate change research is focused on increasing temperatures, there are many side effects of warmer temperatures that could have a profound impact locally. One of those is dust on snow, which the center has been studying for years. Since 2004, the center has been gathering data on the amount of sunlight radiation reflected from the snowpack at sites in Beck Basin. When the snow is clean it reflects more heat and melts slower, but when covered in dust it melts faster. [Researcher Kim Buck] said almost all of the dust on snow in Colorado comes off of the Colorado Plateau. She said once the dust blows in and gets on the snow, it can speed up the melt dramatically — by an entire month in the spring…

Locally, there have been two dust blow-ins this winter, but they were mild compared with dust storms of the past few years, notably 2009, Buck said…

The center’s and NOAA’s snowpack data shows that this year’s snowpack is lower than last year at this time. According to NOAA information, the snowpack in the San Miguel, Dolores, Animas and San Juan River Basin is around 85 percent of normal. Last year it was slightly higher. Buck said it could be bad news this summer.

“It is extremely unlikely that we’re going to catch up on precipitation,” Buck said “Last year the state was just coming off of that great big water year, so reservoirs were full. This year reservoirs are low and then we’re getting another low snow year back to back. So I think the cities in the Front Range will have a pretty hard time in the summer.”


Ridgway Reservoir: Tri-State hopes to start on the hydropower generation facilities in June

March 10, 2013

ridgwaydamusbr.jpg

From The Watch (Peter Shelton):

On the heels of a new Draft Supplemental Environmental Assessment released Feb. 25 by the Bureau of Reclamation, Mike Berry came before the Ouray Board of County Commissioners Tuesday with an update. Berry is general manager of Tri-County Water Conservancy District, which manages the dam and is building the power-generating facility at the base of the dam. Power wholesaler Tri-State Generation and Transmission will receive its permit to begin construction of the interconnection station and transmission lines when BuRec’s final EA is approved. Berry reported that Tri-State hopes to begin construction in June and finish the substation by November or December of this year.

“We hope to have the small generator up and running for this next winter,” Berry told the board. “It should be ready for Aspen’s PPA [Power Purchase Agreement].” The City of Aspen has contracted to purchase the wintertime output from the dam over 20 years. Tri-State, the wholesale electric supplier for San Miguel Power Association and the Delta-Montrose Electric Association, has agreed to purchase, for 10 years, the higher summertime output.

“Aspen probably won’t see any of those actual electrons,” Berry said. “They will most likely go to [the City of] Delta, which shares the same wholesaler, an outfit with the acronym MEAN out of Nebraska.”

Tri-County WCD is installing two generators, a smaller 800kV one that should run efficiently on the low, 30-60 cubic-feet-per-second flows in winter, and a bigger 7.2 megawatt one to run on summertime release levels. Together, they will provide enough juice to run 2,000 homes and take the equivalent, in greenhouse gases, of more than 4,000 cars off the road. The big generator should be ready for testing by April 2014, Berry said.

Water meters may be on the horizon for Ouray

February 10, 2013

ouray.jpg

From the Watch (Samantha Wright):

Council unanimously approved a resolution supporting a $35,000 water efficiency grant application to the Colorado Water Conservation Board to help pay for the development and implementation of a Water Efficiency Plan. The plan was mandated by the Colorado Division of Water Resources last summer, when Ouray’s water supply was called by downstream senior water users.

The ultimate purpose of the Water Efficiency Plan, according to the grant application authored by the city’s water consultant Wright Water Engineers, is to develop a program to better meter water usage and reduce future water demand through multiple steps including leak detection and repair programs; landscape irrigation programs; educational programs on water use; plumbing fixture ordinances and programs and a commitment to track and report progress and make adjustments as needed.

A recent study conducted by Wright Water Engineers showed that residential use accounts for 71 percent of Ouray’s water demand, and that residents use more water than the national average. In implementing the Water Efficiency Plan, the goal is to lower per capita water demands by at least 10 percent over the next decade.

Aspinall Unit operations meeting recap: Forecasted April-July inflow to Blue Mesa is 370,000 acre-feet #coriver

January 28, 2013

aspinallunitdescription.jpg

From email from Reclamation (Dan Crabtree):

Participation: This meeting was held at the Holiday Inn Express in Montrose. Attendees are noted on the distribution list located at the end of these notes. Handouts and presentations are available for review at:

http://www.usbr.gov/uc/wcao/water/rsvrs/mtgs/amcurrnt.html

Purpose of Meeting: The purpose of operation meetings which are held in January, April, and August is to gather input for determining upcoming operations of the Aspinall Unit (Blue Mesa, Morrow Point, and Crystal Reservoirs). This input is used in Reclamation’s development of specific operations for the Aspinall Unit and for the overall 24-month study (www.usbr.gov/uc/water/crsp/studies/index.html) for operation of Reclamation projects in the Upper Colorado River Basin, which includes plans for Glen Canyon, Flaming Gorge, and Navajo Units, as well as the Aspinall Unit. Operation of the Aspinall Unit considers forecasted inflows to the reservoirs, hydropower and flood control needs, existing water rights, minimum instream flows, target elevations for reservoirs; flow needs and flow recommendations for endangered fish and other resources; recreation; and other factors. In addition, the meetings are used to coordinate activities and exchange information among agencies, water users, and other interested parties concerning the Gunnison River.

Handouts provided included data on 2012 operations; inflows to the reservoirs for 2012; and projected most probable, minimum, and maximum inflow forecasts for 2013; and potential operations for 2013.

The Fish and Wildlife Service flow recommendations for endangered fish were completed in 2003 and a final Aspinall Operations EIS and Record of Decision have been completed. Therefore operations to meet the flow recommendations have begun. In addition, the water right for the Black Canyon of the Gunnison National Park has been quantified and adjudicated. These operation meetings are used to discuss proposals for long-term operation plans to address these and related resource management issues.

Operations:

General: Blue Mesa Reservoir capacities are described in meetings as follows: The reservoir holds 940,700 acre-feet (af). Active capacity is 748,400 af; inactive capacity is 81,100af; and dead storage is 111,200. Live capacity is the active plus inactive, which totals 829,500af. Discussions during operation meetings use live capacity.

Gunnison Basin Reservoirs: In 2012, Paonia and Silver Jack were the only Reclamation reservoirs to fill because of the limited runoff; and similar conditions are predicted to occur in 2013. Presently Taylor Park is 53% full; Ridgway 66%; Paonia 7%; and Silver Jack 19%. Inflow forecasts for 2013 are 63% of average to Ridgway; 60-65% to Taylor Park and 65% in the North Fork basin.

2012 Operations: The actual April through July inflow to Blue Mesa Reservoir was 206,000 af, the third lowest since 1937. The years 1977 and 2002 were lower. The April-July runoff at the Whitewater gage near Grand Junction was only 18 percent of average. Maximum content of Blue Mesa in 2012 was 543,000 af in April. Based on the May 1, 2012 inflow forecast to Blue Mesa, the Black Canyon National Park water right called for a 1-day peak of 814 cfs, which was met by an 845 cfs peak at the end of June. Flow Recommendations for endangered fish called for a 900 cfs peak in 2012 at Whitewater and this corresponded to the 900 cfs baseflow target for June and July which was met.

Black Canyon flows from August-September, 2012 were in the 600 cfs range and lowered to 320 cfs in October and remained there for the rest of the calendar year.

Flows at Whitewater Gage held up well through the fall eventually dropping to around 750 cfs in late December.

2013 Operations: Precipitation in the Gunnison Basin in October and November, 2012 was well below 50% of normal; December precipitation was near normal.

As of January 23rd, snowpack in the Gunnison Basin is only 62 % of the long-term average. (We would need 138% of average for the next 5 months to reach an average year). The inflow forecast to Blue Mesa is now 55% of the long-term average.

Blue Mesa content is now 327,000 af and has gained only 2,000 af through the winter.

As of January 15th, the forecasted April-July inflow to Blue Mesa is 370,000 af which is considered a Dry Year category and would be expected to be exceeded in 92 % of years.

If this inflow forecast holds true, it would represent the 5th lowest inflow since Blue Mesa was constructed (1977, 1981, 2002, and 2012 were lower).

Black Canyon National Park peak flow will be based on May 1 forecast; if the present forecast is maintained the peak would be 1016 cfs. However, a drought provision in the water right (based on the previous dry year and low Blue Mesa content) reduces this peak to 768 cfs.

Flow Recommendations call for a 900 cfs peak at Whitewater in a Dry Year based on the present forecasted inflow. This again, is equal to the baseflow target of 900 cfs for June and July.

Under most probable conditions, Blue Mesa is expected to reach 7476 feet in elevation (480,000 af content) which is 43 feet short of filling.

Average monthly Black Canyon flows during January through April are expected to be around 300 cfs and then increase to 500-650 cfs in the spring and summer.

It should be noted that snowpack conditions can change significantly after January and projected operations should be considered preliminary at this time.

Weather Forecasts: The National Weather Service projected some precipitation in the short-term but below average in the 8-14 day period. Last fall El Nino conditions were projected but did not materialize. Conditions are now near neutral and historically such conditions have resulted in a wide range of precipitation conditions; however, below average precipitation for the remainder of the winter is possible.

Above average temperature conditions are projected for the basin for the remainder of the winter (however, valley inversions may make you think otherwise).

Drought conditions in the Gunnison Basin are expected to persist.

Special Flow Requests: None.

Reports:

State Engineer: In 2012 the Uncompahgre River was under call upstream from the M&D Canal beginning May 2. The Gunnison River gage at Gunnison reached record low flows. The North Fork basin and Grand Mesa water conditions were very low and carryover in private reservoirs is very low.

CRWCD: Discussing possible drought response with some of the large senior water right holders. State of the Gunnison River meetings will be held again this year: June 3 in Montrose and May 13 at Colorado Mesa University.

Upper Gunnison District: Lake San Cristobal work has been completed which increases available storage by 950 af.

National Park Service: Despite projected low reservoir levels, should still be good recreation opportunities at Blue Mesa.

Trout Unlimited: Relief Ditch Diversion restoration work is 35% complete and should be done by end of March. Will provide safer boat passage and improved diversion operations.

Delta County: Because of 2012 and 2013 dry conditions, very concerned with fire conditions this year. Noted that Larimer County was under Red Flag condition today.

Colorado Parks and Wildlife: Dan Kowalski has accepted a research position with CPW and his replacement has been selected.

Power Office: Normal maintenance of Aspinall dams and powerplants underway. No special projects.

UVWUA: South Canal hydropower project is under construction and some power may be produced this summer. Fish deterrent at the Gunnison Tunnel entrance has been completed and will be operated in 2013.

Western: Generation limited to 6 hours per day at Morrow Point and Blue Mesa. Crystal is generating using the 300 cfs release. Anticipates purchasing lots of energy this year due to dry conditions; prices are not too high this year. Had a high flow event at Glen Canyon; the high releases will be compensated with lower releases. Requested that National Park and endangered fish peaks be coordinated into one peak operation.

FWS: In January, the FWS proposed the Gunnison Sage Grouse as endangered under the Endangered Species Act. Comments on Federal Register notice are due March 12. Holding public meetings.

Tri-County: Ridgway is 15,000 af lower than January average. Releasing 30 cfs to preserve storage and will remain at 30 cfs until Uncompahgre Project needs water. Hydropower project is under construction and may produce some power by end of year.

BLM: 2012 was fairly slow year in the Gunnison Gorge…low flows make rafting very technical. Noted increase in fishing and recreation downstream from the North Fork confluence.

USGS: Gunnison River at Gunnison will now record water temperature.

Snow and Avalanche Center: One dust event last November 9th. Snowpack very low on study sites.

Next Meeting: April 25th at Reclamation’s Office in Grand Junction.

Montrose County ponies up $50,000 for whitewater park engineering

January 22, 2013

uncompahgrevalleylookingsouthtowardsneffels.jpg

From the Montrose Daily Press (Will Hearst):

The greater Montrose community came one step closer to a collaborative application for a Great Outdoors Colorado grant Tuesday, after the city locked in an agreement with Montrose County for $50,000 toward the engineering of the whitewater park project.

All five city council members voted to accept the $50,000 offered, which will not only help cover the upfront design costs, but make for a much stronger application to GOCO because of the multi-agency participation. In exchange, the county asked that the city contribute an equal amount to an improvement project in the future to the fairgrounds or other county asset.

Councilor Bob Nicholson, while on board with the plan, hesitated at the way a letter worded the county’s agreement. Nicholson said he was more than willing to keep the city’s side of the bargain, but had assumed the county would ask for repayment only for fairgrounds improvements.

Ridgway Reservoir: The Tri-County Water Conservancy District hopes to start turning dirt on hydro facility this fall

October 4, 2012

ridgwaydamusbr.jpg

From The Watch (Kati O’Hare):

In about a month, district officials are hopeful they it will be able to break ground on the project, which, upon completion, will create about $1 million annually in revenues and produce enough electricity for 3,000 houses each year.

The 8-megawatt project will contain two turbines and two generators — a 1.8-mw system that will operate in the winter months during lower flows, and a 7.2-mw system for the higher-flow irrigation months.

“Winter flows are significantly less than our summer flows, and we can’t get a generator that would operate efficiently for that wide range,” Tri-County Water General Manager Mike Berry said.

The two different systems, both of which can operate during peak flows, is the most efficient method of capturing energy from the dam, he said.

Tri-County Water has gone through the necessary steps to get the project underway, and is now waiting for the completion of just two items before construction begins: the design plans need final approval from the Bureau of Reclamation, and interconnection agreement — to allow the power that’s captured to be transferred onto the grid — must be reached between Tri-County Water and Tri-State Generation and Transmission.

Aspinall Unit update: 400 cfs in the Black Canyon

September 29, 2012

blackcanyoninnercanyonnps.jpg

From email from Reclamation (Erik Knight):

With the recent rains, flows in the Gunnison River at the Whitewater gage are well above the September baseflow target of 890 cfs. Short term forecasts predict flows will stay above 1000 cfs while the baseflow target for October drops down to 790 cfs. Considering all this, releases from Crystal Dam will be reduced on Saturday, September 29th, with the intention of maintaining 400 cfs in the Gunnison River through the Black Canyon (down from the current flow of 480 cfs).

In the next couple weeks, decreasing irrigation demands will result in less diversion into the Gunnison Tunnel which may necessitate changes at Crystal Dam. Releases may be reduced further in light of the lower Whitewater gage baseflow target for October if rainfall and tributary flows continue to support flows in the lower mainstem of the Gunnison River.

The Water Center at CMU is hosting a water law seminar and a tour of the Uncompahgre Valley

September 14, 2012

gunnisontunnelnps.jpg

From Colorado Mesa University (Hannah Holm) via the Grand Junction Free Press:

The Water Center at Colorado Mesa University is pleased to announce two exciting opportunities to learn about water in our region: An eight-hour “Water Law in a Nutshell” class Sept. 21, and a water tour of the Uncompahgre Valley Sept. 25. Both events are open to the general public.

• “Water Law in a Nutshell” – Friday, Sept. 21, 8 a.m.-5 p.m.

Do you have some understanding that senior water rights have priority over junior water rights in Colorado, but get a bit confused when people start talking about augmentation plans and conditional water rights? Are you a little fuzzy on the difference between a ditch share and a water right? And would you like to understand all of this a whole lot better? If so, then this course is for you.

The Water Center at CMU will host “Water Law in a Nutshell,” presented by Aaron Clay, attorney at law and former 26-year Water Referee for the Colorado Water Court, Division 4. This seminar will cover all aspects of the law related to water rights and ditch rights as applied in Colorado. Subject matter includes the appropriation, perfection, use, limitations, attributes, abandonment and enforcement of various types of water rights. Additional subject matter will include special rules for groundwater, public rights in appropriated water, federal and interstate compacts and more.

This seminar is open to all interested persons. Fee is $89; $113 for .5 graduate in-service credit. The course has also been pre-approved for eight hours of Continuing Legal Education credit. For more information or to register, see http://www.coloradomesa.edu/eso/WaterLaw.html or call the Water Center at 970-248-1968.

• Uncompahgre Valley Water Tour – Tuesday, Sept. 25, 7:30 a.m.-5 p.m.

Over 100 years ago, a tunnel was drilled from the Black Canyon of the Gunnison to carry water from the Gunnison River to the Uncompahgre Valley. The water flowed, and a rich diversity of farms flourished.

In an all-day tour Sept. 25, you can learn about this fascinating history and see how the valley is responding to newer challenges: The opportunity to develop hydropower from canals, the need to control the levels of salt and selenium leaching from farmland into the Uncompahgre and Gunnison rivers, and the need to get more precise with irrigation when water supplies dwindle.

The tour will start and finish at the Bill Heddles Recreation Center at Confluence Park in Delta, and is being co-hosted by the Uncompahgre Valley Water Users Association, the Delta-Montrose Electric Association, and the Water Center at CMU.

The tour will begin with a presentation on the history of water development in the Uncompahgre Valley by Steve Fletcher, manager of the Uncompahgre Valley Water Users Association. Stops will include the South Canal hydropower project, which is currently under construction; the Ironstone diversion on the Uncompahgre River; a ditch lining project on the EC lateral; Randy Meeker’s farm; and David Harold’s farm. Meeker employs sprinkler irrigation, and Harold uses a drip system.

The tour is open to anyone who is interested. The $40 fee includes transportation, breakfast and a picnic lunch at the Mountain View Winery near Olathe. For more information or to register, see http://www.coloradomesa.edu/watercenter/UncompahgreTour.html or call the Water Center at 970-248-1968.

Uncompahgre River Watershed: ‘Good Samaritan’ clean up of Red Mountain Creek in the offing?

August 3, 2012

redmountaincreekacidminedrainage.jpg

From The Telluride Watch (Samantha Wright):

The Uncompahgre Watershed Partnership, a grassroots coalition of citizens, nonprofits, local and regional governments, and federal and state agencies dedicated to understanding the Uncompahgre Watershed, would like to do something about this caustic problem child. Red Mountain Creek is, after all, a tributary of the Uncompahgre River, and one of the main reasons why the southernmost portion of the river is deemed “impaired” – or, as some would say, dead, because it cannot support aquatic life.

The coalition has recently identified its top priority as improving water quality so as to remove impaired segments of the Uncompahgre River from the State of Colorado’s list of impaired streams.

Thus, Przeszlowska is watching with interest current efforts headed up by U.S. Senator Mark Udall (D-Colo.) to find a way to allow so-called Good Samaritans (ranging from individuals to citizen groups like UWP to governmental and nongovernmental agencies) to take on projects to improve water quality in areas where there are abandoned mines, without fear of incurring liability under the Clean Water Act.

Reclamation experts have found plenty of ways to shore up leaky old mines and reduce acid mine drainage flowing into impaired watersheds. These range from simple fixes, like reducing the amount of water entering into the mine by building plugs or diverting the water around old workings, to treating drainage with settling ponds, wetlands, limestone drains, or some other form of passive or active treatment.

But certain provisions in the federal Clean Water Act create major stumbling blocks to such efforts. The Clean Water Act likes big, perfect fixes – like permanent water treatment pants that cost millions to build and millions more annually to operate, and which convert toxic water into potable stuff that fish can cruise around in.

So-called Good Samaritans have had to walk away from more modest mine cleanup projects for fear that if they don’t bring the discharge water all the way up to CWA standards, they may be sued by a third-party citizen or even another environmental group.

Pat Willits, the executive director of the Ridgway-based Trust for Land Restoration, which helps communities deal with a myriad of issues related to abandoned mining, explains the liability problem like this: “Good Samaritans are spooked by the ‘citizen suit’ provision of the Clean Water Act, which says that if someone suspects a violation of the Clean Water Act, a citizen may begin a legal action and if successful, the defending party will have to pay all of the legal expenses of the citizen’s group. If they are unsuccessful, the defendant does not have recourse to countersue.”[...]

Two decades’ worth of efforts to shield would-be Good Samaritans legislatively by creating a new provision in the Clean Water Act (including, most recently, U.S. Senator Mark Udall’s Good Samaritan Cleanup of Abandoned Hardrock Mines Act of 2009), have floundered in Congress, due to fears from environmentalists about opening up the Clean Water Act, even for such benign and altruistic purposes as protecting Good Samaritans…

Fed up with past efforts, Udall is now taking a new approach. He believes that updating, or even simply clarifying, Environmental Protection Agency policy may accomplish pretty much the same thing as legislation in terms of affording legal protection to Good Samaritans.

The agency already has some existing guidance that encourages potential Good Samaritans to enter into voluntary agreements with EPA or federal land management agencies that helps to facilitate certain kinds of Good Samaritan cleanups.

As they stand, these protections are considered good enough protection for Good Samaritans to undertake reclamation projects that do not include direct attempts to improve water quality beyond, for example, rerouting a stream so it does not flow through a mining waste dump, or preventing water from flowing into old mine workings.

Montrose: The Montrose County Commissioners endorse the the town’s whitewater park application

August 3, 2012

uncompahgreriver.jpg

From The Telluride Watch (Katie O’Hare):

City Councilors and the Montrose Recreation District board asked county commissioners to the table on July 31 to discuss if the county was willing – and at what cost – to support a project that would include creating a whitewater park along the Uncompaghre River at Riverbottom Park.

The city teamed up with MRD hoping to submit a Great Outdoors Colorado grant application by Aug. 29 that could provide $350,000 toward the project, which includes improvements to the MRD’s ball fields and surrounding areas, also in Riverbottom Park.

“In principal, it’s all about improving the community for all of us,” said Kerwin Jensen, City of Montrose community development director.

After a two-hour meeting, commissioners David White and Gary Ellis – who did most of the talking for the county – agreed to put the request for funding help on their regular commissioner meeting agenda for Monday, Aug. 6…

The city staff stressed the economic benefits the county could see from having a whitewater park in Montrose, which included increased tourism and new businesses to cater to those visitors, as well as the recreational opportunity it would provide county residents.

“Economic development is number one in our strategic plan, and things like this contribute to that,” Commissioner David White said.


Aspinall Unit operations update: Black Canyon streamflow between 500 and 600 cfs

July 26, 2012

aspinallunit.jpg

From email from Reclamation (Erik Knight):

Flows in the Gunnison River at the Whitewater gage continue to fluctuate with the periodic rainfall. Reclamation intends to meet the flow target of 900 cfs at the Whitewater gage through the end of July. The target will drop to 890 cfs starting August 1st. Releases from Crystal Dam will continue to cause flows in the Gunnison River through the Black Canyon to fluctuate between 500 cfs and 600 cfs.

Aspinall Unit update: Monsoon moisture helps streamflow in the Gunnison River #CODrought #monsoon

July 16, 2012

aspinallunitdescription.jpg

From email from Reclamation (Dan Crabtree):

The rain came through this weekend and flows at the Whitewater gage have now reached 1400 cfs. Rain is expected to continue today and then taper off by Wednesday. Diversions at the Gunnison Tunnel are also decreasing by 50 cfs this morning. In order to further water conservation in the Aspinall Unit reservoirs, we will match the tunnel decrease from Crystal Dam plus an additional decrease of 100 cfs because of the higher flows at the Whitewater gage. After this change, flows in the Gunnison River through the Black Canyon should drop to about 520 cfs.

More Aspinall Unit coverage here.


Aspinall Unit update: 620 cfs in the Gunnison River through Black Canyon #CODrought

July 15, 2012

gunnisonblackcanyon.jpg

From email from Reclamation (Erik Knight):

Even with the last couple release increases at Crystal, flows in the Gunnison River at the Whitewater gage are still below the 900 cfs target. Therefore releases at Crystal Dam will be increased by another 50 cfs today, July 13th. Hopefully with some help from rainfall over the weekend, this will be enough to push flows back up to the target level. This operation should cause flows in the Gunnison River through the Black Canyon to increase to about 620 cfs.

Aspinall Unit operations update: 500 cfs in Black Canyon

July 6, 2012

blackcanyoninnercanyonnps.jpg

From email from Reclamation (Dan Crabtree):

The Gunnison Basin is finally receiving some measurable precipitation from the monsoonal conditions. In order to take advantage of it and conserve storage in the Aspinall Unit, Reclamation will be decreasing releases from Crystal Reservoir by 100 cfs this afternoon. Following the change, flows in the Black Canyon and Gunnison Gorge will be about 500 cfs. With the current flow forecast, the target flow of 900 cfs at the Whitewater gage should be maintained or exceeded through this weekend and beginning of next week. However, releases will likely increase again next week as the monsoonal flow dissipates.

Colorado Water 2012: The Gunnison River Basin is home to Colorado’s largest reservoir — Blue Mesa

July 3, 2012

gunnisonriverbasin.jpg

Here’s the latest installment of the Valley Courier’s Colorado Water 2012 series. Frank Kugel details water operations and facilities in the Gunnison Basin. Here’s an excerpt:

The Gunnison Basin is home to the largest body of water entirely within the state of Colorado, Blue Mesa Reservoir, which has a capacity of 940,000 acre-feet (830,000 acre-feet active capacity). It is the primary storage component of the three reservoirs comprising the Aspinall Unit. Morrow Point Dam is the middle structure and its primary purpose is production of hydropower. Crystal Dam creates a stabilizing reservoir for the variable flows produced by Morrow Point Dam releases. Below Crystal lies the Black Canyon of the Gunnison River National Park…

The Bureau of Reclamation has a number of other storage projects in the basin, in addition to the Aspinall Unit reservoirs, including Taylor Park on the Taylor River, Ridgway on the Uncompahgre River, Silver Jack on the Cimarron River, Crawford on the Smith Fork of the Gunnison, fruit growers on Current Creek and Paonia on Muddy Creek, tributary to the North Fork of the Gunnison River.

One of the first projects developed by the Bureau of Reclamation was the Uncompahgre Project, which provides irrigation water for a variety of crops in the Uncompahgre Valley between Colona and Delta. A key component of the project is the Gunnison Tunnel, a 5.7 mile long tunnel that diverts water from the Black Canyon of the Gunnison and discharges it into a series of canals in the Uncompahgre Valley. The tunnel has a 1913 water right for 1300 cfs and supplies some 60% of the irrigation water for the 76,000 acres under the project.

Taylor Park Dam was constructed in 1937 to provide supplemental irrigation for the Uncompahgre Valley. Taylor Park Reservoir has a capacity of 106,230 acre feet. The 1975 Taylor Park Exchange Agreement allows for transfer of storage downstream to Blue Mesa Reservoir to provide the Gunnison Tunnel with a more readily available source of irrigation water. An additional benefit of this exchange was the flexibility to make releases in time and amount that would benefit recreational and agricultural users in the Upper Gunnison basin.

Aspinall Unit operations update: 700 CFS in Black Canyon

June 13, 2012

aspinallunitdescription.jpg

From email from Reclamation (Erik Knight):

Tributary contributions to the Gunnison River have continued to decline and it appears the last gasps of snowmelt have reached the rivers. Once again, the gage at Whitewater is forecast to drop below 900 cfs before this weekend. Therefore flows in the Gunnison River through the Black Canyon have been increased to 700 cfs as of late this morning, Wednesday, June 13th.

Current forecasts suggest this will be enough water to keep the Whitewater gage above the 900 cfs target described in the Aspinall Unit Operations Record of Decision (ROD) for a period that is hopefully longer than one week. River flows are projected to taper off more slowly as we exit the runoff period and enter into summertime baseflows.

More Aspinall Unit coverage here.


Aspinall Unit operations update: 600 cfs in Black Canyon

June 9, 2012

gunnisonblackcanyon.jpg

From email from Reclamation (Erik Knight):

Warm and windy conditions have continued to contribute to declining flows in the lower Gunnison River. Model forecasts show river flows at the Whitewater gage dropping around 100 cfs over this weekend, and this accounts for the 100 cfs increase from the Aspinall Unit yesterday afternoon. Therefore flows in the Gunnison River through the Black Canyon will be increasing to 600 cfs late this afternoon, Thursday, June 7th.

Current forecasts suggest this will be enough water to keep the Whitewater gage above the 900 cfs target described in the Aspinall Unit Operations Record of Decision (ROD) through the end of next week. River flows are projected to continue their decline however, so additional releases may be necessary to maintain flows in the lower Gunnison River as dry conditions continue.


Aspinall Unit operations update: Releases from Crystal Dam to bolster streamflow in Black Canyon of the Gunnison River

June 6, 2012

blackcanyoninnercanyonnps.jpg

From email from Reclamation (Erik Knight):

Flows in the Gunnison River through the Black Canyon will be increasing to 500 cfs tomorrow, Wednesday, June 6th , in response to decreasing flows in the lower Gunnison River. Pursuant to the Aspinall Unit Operations Record of Decision (ROD), the flow target in the lower Gunnison River, as measured at the Whitewater gage, is 900 cfs for June and July. Flows are forecasted to drop below this level by the end of the week without additional releases from the Aspinall Unit. Therefore releases from Crystal Dam will be increased by 100 cfs late afternoon on Wednesday, June 6th.

Uncompahgre River: Work begins on $22 million South Canal hydroelectric generation project

May 28, 2012

southcanalhydroelectricsitethetelluridewatch1.jpg

From the Montrose Daily Press (Will Hearst):

Ground was officially and symbolically broken Friday along Montrose’s South Canal just below the outflow of the Gunnison Tunnel for a $22 million hydroelectric project…The project will actually consist of two sites separated by a little more than a mile. The sites were selected from five identified more than 20 years ago as having a gradient steep enough to efficiently generate power without requiring a dam. From those two sites, DMEA will produce more than 6,000 kilowatts of power, which converts to 27 million kilowatt hours of electricity — enough to power more than 3,000 homes.

Ouray: Crystal Lake Dam to get new outlook works over the summer

May 2, 2012

crosssectionearthdam.jpg

From the Montrose Daily Press (Katharhynn Heidelberg):

A massive repair project is expected to interrupt summer fishing at Crystal Lake Dam above Ouray — there is no other way to make the critical safety augmentations but to close the structure for a few months, starting in early July. “Probably about 50 percent of the dam will be removed and taken off-site. They’ll install a new outlet works,” said Tom Condos, engineering and minerals staff officer with the U.S. Forest Service. The dam provides water storage for the Uncompahgre River headwaters. During an inspection two years ago, officials noticed a problem.

From Colorado Radio (James MacDonald):

The Crystal Lake Dam near Ouray is going to be getting some major repairs. The dam will be closed this summer and partially removed to make the proper repairs and upgrades. The $300,000 project will also include the installation of an emergency spillway for the dam. The closure is slated for July and the repairs will force fishermen to look elsewhere until the project is completed in October.

Aspen: City council okays purchase of power from new hydropower facility planned for Ridgway Dam

April 26, 2012

ridgwaydamusbr.jpg

From the Aspen Daily News (Curtis Wackerle):

Aspen electric utility officials presented details of the proposal to City Council at a work session Tuesday. Nearly a decade ago, city officials began discussions with Tri County Water Conservancy District (TCWCD) officials about plans to retrofit the existing Ridgway Reservoir dam with two turbines to generate hydropower. The new facilities are expected to come online in 2015.

The city has worked out a deal with TCWCD and the Municipal Energy Agency of Nebraska (MEAN), which supplies Aspen with wind and coal power to supplement locally generated hydropower. Under the deal, Aspen will essentially swap coal-fired power from MEAN with power from the Ridgway dam during the winter months. The city will pay the same rate for the Ridgway power that it pays the Nebraska provider, which is 5.9 cents per kilowatt hour. The initial contract is for a 20-year agreement with MEAN and the Ridgway facility operators.

The city will only buy the Ridgway power during the winter months, as that is when Aspen’s demand peaks, but also when the supply of local hydropower is at its lowest.

“It fits our energy requirements like a well-tailored glove,” city utilities director David Hornbacher said of the Ridgway facility.

Aspinall Unit update: Inflows to Blue Mesa revised to 330,000 acre-feet, 49% of average

April 4, 2012

aspinallunit.jpg

From email from Reclamation (Erik Knight):

The April 1st forecast for spring runoff to Blue Mesa Reservoir has been issued and the numbers keep dropping. This forecast now predicts 330,000 acre-feet of runoff between April and July, which is 49% of average. Warm and dry conditions have caused the forecast to drop 90,000 acre-feet since the mid-March forecast. The monthly runoff distribution also shows an increase in the April runoff volume while all other months decrease, indicating an early runoff. For comparison, this forecasted runoff volume is lower than every year’s runoff volume since 2000 except for 2002.

Given this information, flows in the Gunnison River through the Black Canyon will be dropping to 400 cfs today, Wednesday, April 4th, as diversions through the Gunnison Tunnel increase.

Reclamation plans to operate the Aspinall Unit to allow the Black Canyon of the Gunnison River one day peak flow target to be met. Under the current forecast this target is approximately 960 cfs. The final determination of the spring peak target will be made upon issuance of the May 1st forecast by CBRFC.

Using the current forecast the peak flow target at the Whitewater gage is 900 cfs. Reclamation expects this flow target to be met in conjunction with the spring peak flows in the Black Canyon of the Gunnison River.

As a reminder, the April Aspinall Operations Meeting will be held in Reclamation’s Western Colorado Area Office, Grand Junction location, on April 26th beginning at 1:00 p.m.

Aspinall Unit update: Deliveries through the Gunnison Tunnel to start on Monday, spring has sprung

March 16, 2012

gunnisontunnelnps.jpg

From email from Reclamation (Dan Crabtree):

For those that work in an office all day and haven’t noticed, it has become quite warm outside. It appears spring has arrived and with that, it is time for the Gunnison Tunnel to start diverting water. The Uncompahgre Valley Water Users Association (UVWUA) plans to start tunnel diversions on Monday, March 19th. Initially diversions will start at 200 cfs. At this same time the UVWUA will need to complete some repair work on the apron of the diversion dam. This will require flows in the Gunnison River be reduced to approximately 400 cfs so that no water is spilling over the diversion dam. Work on the dam apron will be completed by the end of Tuesday, March 20th. At this time, Crystal Dam will increase releases by 100 cfs while the Gunnison Tunnel continues diverting 200 cfs. The resulting flow in the Gunnison River through the Black Canyon will be around 500 cfs.

Gunnison Tunnel diversions may increase later in the week of the 19th and releases at Crystal will be increased accordingly to maintain the 500 cfs flow in the Gunnison River.

Under the current forecast, Reclamation plans to operate the Aspinall Unit to allow the Black Canyon of the Gunnison one day peak flow target of approximately 2,200 cfs to be met; the timing of which is unknown at this time.

As a reminder, the April Aspinall Operations Meeting will be held in Reclamation’s Western Colorado Area Office, Grand Junction location, on April 26th beginning at 1:00 p.m.

Please contact Dan Crabtree or Erik Knight at the Bureau of Reclamation with questions regarding this operation.

Reclamation Releases Final Aspinall Unit Operations Environmental Impact Statement

March 7, 2012

aspinallunitdescription.jpg

Here’s the release from the U.S. Bureau of Reclamation (Steve McCall/Justyn Hock):

Reclamation’s Western Colorado Area Office announced today the release of the final Aspinall Unit Operations Environmental Impact Statement. The purpose of the EIS is to outline Aspinall Unit operations to avoid jeopardy to downstream endangered fish species while continuing to meet the congressionally authorized unit purposes. In general, new operations will provide higher spring flows and protect base flows in the Gunnison River. Reclamation will not make a decision on the proposed action until at least 30 days after release of the FEIS. After the 30-day public review period, Reclamation will complete a record of decision which will state the action to be implemented and discuss all factors leading to that decision.

If you have questions or need additional copies of the final EIS, please contact Steve McCall at 970-248-0638 or Terry Stroh at 970-248-0608. The final EIS is also available on Reclamation’s web site.

Reclamation To Issue a Lease of Power Privilege Permit for a Proposed Hydropower Project on the South Canal Near Montrose

March 3, 2012

southcanalhydroelectricsitethetelluridewatch1

Here’s the release from the U.S. Bureau of Reclamation (Steve McCall/Justyn Hock):

Reclamation announced today that it will issue a Lease of Power Privilege to the Delta-Montrose Electric Association and the Uncompahgre Valley Water Users Association to develop hydropower resources on the South Canal, a feature of Reclamation’s Uncompahgre Irrigation Project.

Reclamation will issue the LOPP based on the final environmental assessment and Finding of No Significant Impact for the proposal. These documents have been completed in compliance with the National Environmental Policy Act to address the effects of the construction and operation of hydropower facilities.

Federal policy encourages non-federal development of environmentally sustainable hydropower potential on federal water resource projects. The LOPP will ensure that the development of hydropower is consistent and compatible with existing operations and purposes of the Uncompahgre Project.

The final EA and FONSI are available on Reclamation’s web site or a copy can be obtained by contacting Steve McCall at (970)248-0638.

More coverage from Katharhynn Heidelberg writing for the Montrose Daily Press. From the article:

“It’s big news for us and big news for the Western Slope,” said Tom Polikalis, DMEA spokesman. “This will be the first utility scale project undertaken” by DMEA…

Plans are to construct two power houses on the South Canal, starting with a location at the far eastern end of Miguel Road. A second power house is to be built about 1.5 miles downstream on the canal’s “third” drop. When the project is complete, and depending on canal flows, DMEA expects to generate 6.5 to 7 megawatts — enough for 3,000 homes. (A megawatt is 1,000 kilowatts.)

Montrose: Ag energy/water workshop March 1

February 27, 2012

nolandoesken1

Here’s the release from the Delta-Montrose Electric Association and Colorado State University via the Delta County Independent:

Are you looking for ways to improve energy efficiency on your farm, ranch, or small acreage? Are you looking to enhance your soil health with a new tool for your irrigation management toolbox?
If so, then you might want to register for a free workshop focused on ag energy and the local agricultural weather station network.

The workshop is from 9 a.m. to 3:30 p.m. on Thursday, March 1, in Montrose with a complimentary lunch from Camp Robber for all who register by Monday, Feb. 27.

The workshop — co-hosted by Delta-Montrose Electric Association (DMEA) and Colorado State University (CSU) — will be held in the DMEA’s classroom at 11925 6300 Rd, near the airport just north of Montrose. Staff of both DMEA and CSU will outline local and statewide programs that can improve efficiencies with energy and water use, and provide a foundation for a more profitable and sustainable agricultural operation.

Included in the program is a visit from state climatologist Nolan Doesken, whose enthusiasm for all things weather has helped raise the profile of water — particularly in the form of rain, snow, sleet, or hail — on both sides of the divide.

Recently Doesken was in western Colorado advancing his campaign to place a rain gauge in every school around Colorado. Now he’s back to engage with local producers and promote CSU’s imminent upgrades to the Colorado Agricultural Meteorological (CoAgMet) network. CoAgMet is a network of about 65 weather stations around the state that provide accurate crop water use and disease pressure data for farmers and ranchers. Doesken describes CoAgMet’s importance to the irrigation community as “the primary source of local and accurate crop water use information.”

Troy Bauder, the state water quality specialist at CSU, adds, “This information is one tool we’d like to get in the hands of irrigators that are interested in more precise irrigation scheduling, particularly those who might have a newer system and want to fully utilize its capabilities to deliver water according to crop needs.”

Indeed the entire afternoon session of the workshop will provide local irrigators a golden opportunity to become more familiar with CoAgMet, learn how CSU intends to make it work better, and to provide much needed feedback to Doesken, Bauder, and CSU staff on the upcoming improvements.

Jim Heneghan of DMEA and Abbie Brewer with the Governors Energy Office at DMEA (Fore Alliance), along with Cary Weiner, clean energy specialist with CSU Extension, will be hosting the morning session. Weiner will be discussing the benefits of on-farm energy audits, while Heneghan and Brewer will outline DMEA initiatives such as progress with the South Canal micro-hydro feasibility study, and the Business Energy Assessment Team (BEAT) program available to business owners and managers in the Delta-Montrose area. Heneghan — who also farms near Olathe — explains his support for the workshop, “DMEA is very interested in smart energy products for its service area. We believe that helping local residents understand where the opportunities lie for energy savings can help them be more successful with their agricultural operations, businesses, and home maintenance.”

From email from Reclamation (Erik Knight):

The February 1st forecast is out and the prediction is still for 450,000 acre-feet of inflow to Blue Mesa Reservoir during the April-July runoff period. This represents 67% of the current 30 year average. In response to the continuing dry conditions, releases at Crystal Dam will be reduced by 200 cfs on Wednesday, February 8th. This will bring releases down to 600 cfs and with no Gunnison Tunnel diversions, flows in the Gunnison River through the Black Canyon should also be around 600 cfs.
