Reservoir Storage in Great Shape
Colorado-Big Thompson Project reservoir levels are in great shape. As of July 1, total C-BT Project reservoir storage was approximately 99 percent of capacity. On the West Slope, Lake Granby had 536,061 AF in storage, while on the East Slope, Carter Lake and Horsetooth Reservoir held 108,383 AF and 154,386 AF in storage, respectively.

The relatively high storage volumes in July were partially due to low water deliveries. From the beginning of the water year through July 1, only 39,602 AF was delivered, including quota, carryover and Regional Pool Program water. Deliveries have increased in the past two weeks as a result of agricultural users requesting more water to meet peak irrigating season demands.

From The Denver Post (Danika Worthington):

The auction of family-owned Reynolds Farm outside Mead raked in $12.6 million Thursday, as farmers, developers and five cities bid for land and the attached water and ditch rights.

The auction room was packed with bidders, but only 13 emerged from the Larimer County Fairgrounds with a piece of the Reynolds portfolio. Municipalities, developers and farmers all grabbed some units of Colorado-Big Thompson water, while developers and growers signed deals for land.

The auction was of high interest, given the land’s location in the path of northern Front Range development and the large amount of water attached to it.

Although the numbers are still preliminary, Hall and Hall Auctions partner Scott Shuman said 276 CB-T units brought in the largest chunk of money, about $7.6 million or an average of $27,356 each. The CB-T units, already trading for high sums, were expected to be the most pricey given their scarcity and the ability to use the water for uses such as agriculture, development and industrial processes, including oil and gas extraction.

But on a per-share basis, the 15.75 Highland Ditch shares stole the show, averaging $148,900 each for an estimated total of $2.3 million. All the shares were sold to farmers or investors.

Arkansas River Basin: “Those releases help keep the rafting industry afloat” — Alan Ward

From The Pueblo Chieftain (Chris Woodka):

After a wet spring, summer has been relatively dry, and drought conditions are creeping back into Colorado, particularly over the Rocky Mountains in the center of the state and the Rio Grande basin.

River flows have dropped, so Reclamation and Pueblo Water are running water from accounts in upper reservoirs to Lake Pueblo. This serves two purposes: Creating space for imports next spring and providing water for the voluntary flow program that extends the commercial rafting season.

Finding the additional space in Clear Creek, Twin Lakes and Turquoise reservoirs was problematic this year, because reservoirs still were full from a very wet 2015. Twin Lakes filled early with native water and delayed imports from the Western Slope.

The Fryingpan-Arkansas Project has delivered more than 58,760 acre-feet so far, about 90 percent of what had been expected when allocations were made in May.

The Southeastern District, which determines allocations, will adjust agricultural deliveries, because cities already had requested less water than they were entitled to receive.

Pueblo Water imported about 13,500 acre-feet of water, about 92 percent of normal. Part of the reason was the lack of free space at Twin Lakes, and part was due to maintaining long-term limits since storage space was scarce anyway, said Alan Ward, water resources manager.

Pueblo Water will lease more than 21,700 acre-feet of water this year because of the potential storage crunch earlier this year.

Even so, Pueblo Water had 49,133 acre-feet of water in storage at the end of June, which was down from last year, but 17,600 acre-feet more than was in storage at the end of May. Most of the gain came in the upper reservoirs, and is now being sent to Lake Pueblo, where it is needed for leases and to make space, Ward said.

“Those releases help keep the rafting industry afloat,” Ward said.

@USBR Releases Draft Environmental Assessment for Tri-Districts Long-Term Excess Capacity Contracts

Here’s the release from Reclamation (Buck Feist):

The Bureau of Reclamation has released the Draft Environmental Assessment (EA) for the proposed Tri-Districts Long-Term Excess Capacity Contracts for public review and comment.

The Draft EA evaluates environmental impacts associated with Reclamation’s proposed approval of 40-year excess capacity storage, exchange, and conveyance contracts between Reclamation and East Larimer County Water District, Fort Collins-Loveland Water District, North Weld County Water District (collectively referred to as Tri-Districts).

“Excess capacity contracts are very important,” said Eastern-Colorado Area Manager, Signe Snortland. “These provide a needed benefit of water management flexibility, so Districts are better equipped to address drought, changes in municipal demand, and temporary changes in the watershed affecting water quality.”

Tri-Districts have annually requested annual excess capacity contracts to mitigate poor water quality conditions in the Cache La Poudre River due to increased particulate matter due to the High Park and Hewlett wildfires in 2012. The long-term contracts would allow Tri-Districts to utilize excess capacity in Horsetooth Reservoir for storage, exchange and conveyance of the Tri-Districts’ water supplies for delivery to the Soldier Canyon Water Treatment Plant. Each district would execute a separate contract with combined total exchange and storage contract volumes not to exceed 3,000 acre-feet (af).

The Draft EA is electronically available at http://www.usbr.gov/gp/ecao/nepa/cbt_tridistricts.html.

Comments on the Draft EA can be sent to: tstroh@usbr.gov; Terence Stroh, Bureau of Reclamation, 11056 West County Road 18E, Loveland, CO 80537; or faxed to 970-663-3212. For additional information or to receive a printed copy of the Draft EA, please contact Terence Stroh at 970-962-4369 or tstroh@usbr.gov. Reclamation requests comments on the Draft EA on or before August 5, 2016.

Denver Water digs into Vasquez Canal Project — The Sky-Hi Daily News

From the Sky-Hi Daily News (Lance Maggart):

The Vasquez Canal Project is a multi-year multi-million dollar project that continues efforts by Denver Water to improve existing water diversion infrastructure. Work on the Vasquez Canal Project focuses on removing sections of the existing Vasquez Canal and replacing removed sections with a 114-inch diameter concrete reinforced pipe.

Work on the project has occurred in previous year with Denver Water replacing between 5,000 and 6,000 feet of the Vasquez Canal over the past two decades. Officials from Denver Water say they plan to replace about 2,000 feet of the Vasquez Canal in 2016, leaving roughly 15,000 feet to be replaced in the future.

Officials from Denver Water did not provide an overall projected cost on the project pointing out that, “funding allocation for this project is reassessed annually”. In previous year the project averaged around $750,000 per year in costs. Future projected cost estimates on the Vasquez Canal Project total between two to three million dollars annually.

Monies used for the project come directly from Denver Water which is funding operation, as it does all operational and capital projects, through water rate fees, bond sales, cash reserves, hydropower sales and system development charges for new services.

Work on the Vasquez Canal Project consists primarily of excavation and earth moving to facilitate the canal upgrade. “Crews will demolish the old concrete liner and covers, excavate the area and install the new 114-inch pipe, piece by piece,” stated Denver Water Communication Specialist Jimmy Luthye. Luthye explained Denver Water plans to, “work aggressively to complete this project in the next few years in an effort to replace aging infrastructure and improve the safety and strength of the entire water system.”

Ames Construction is the contractor of record for the project. For the past 20 years though, as previous sections of the Vasquez Canal have been replaced, employees of Denver Water performed the upgrade work. According to Denver Water this is the first year work on the project has been contracted out.

The Arapaho National Forest prepared an environmental assessment of the Vasquez Canal Project. All construction work on the project is being conducted entirely on National Forest System Lands. According to Denver Water that environmental assessment determined, “there would be no significant environmental impacts.” Officials from Denver Water went on to state, “They approved the project along with required best management practices, design criteria and monitoring designed to protect the area during construction.”

The Vasquez Canal is part of Denver Water’s historic water diversion network that brings mountain runoff to the Front Range and Denver Metro area. The original canal was completed in the late 1930s. According to Denver Water, information on the original construction of the canal is fairly limited but officials from the municipal water supplier stated, “we suspect that some of it (Vasquez Canal) was originally dug by hand because the canal had to be cut into the side of a steep mountain… making it difficult for machines to access.”

In the late 1950s Denver Water covered the originally open Vasquez Canal, effectively creating a tunnel. A drought during the early 1950s prompted the action, which was intended to mitigate evaporation as water traveled through the diversion system.

Water utilized by the Denver Water’s diversion system follows a zigzagging path of infrastructure as it descends from snowmelt in the high Rockies to homes along the Front Range.

Diversion structures in the Upper Williams Fork River send water through the Gumlick Tunnel, formerly known as the Jones Pass Tunnel, where the water passes under the Continental Divide. From there water travels through the Vasquez Tunnel, which brings the water back through to the other side of the Continental Divide, where it enters into Grand County and Vasquez Creek. The water is then diverted through the Moffat Tunnel back under the Continental Divide for a final time and into South Boulder Creek, feeding into Gross Reservoir, a major water storage reservoir for Denver Water.

Open house for #Colorado Springs’ new SDS pipeline draws 1,200 — The Colorado Springs Gazette

From The Colorado Springs Gazette (Matt Steiner):

More than 1,200 people endured 90-degree temperatures Saturday in eastern Colorado Springs to learn more about Colorado Springs Utilities’ new Southern Delivery System.

During the SDS Waterfest at the Edward W. Bailey Water Treatment Plant on Marksheffel Road, kids and adults interacted with community volunteers at hands-on educational booths. And most of those on hand were treated to a guided tour of the state-of-the art facility…

David Schara, 42, said he is a Colorado Springs native and has watched as CSU and city officials spent more than 20 years planning the Southern Delivery System which began piping water north out of Pueblo Reservoir in late April.

“It’s much needed,” David Schara said. “As the city grows, they had to do something.”

David Schara said he and others have been skeptical over the years since CSU introduced the SDS in the Colorado Springs Water Plan of 1996. According to Schara, the biggest concern was about the capacity of Pueblo Reservoir, which he said has been “pretty low at times.”

The Southern Delivery System cost $825 million. Forte said that presently the SDS takes care of about 5 percent of the Colorado Springs Utilities customers and produces about 5 million gallons of water each day.

During Saturday’s event, CSU handed out free water bottles and had refill stations throughout the event where visitors could rehydrate with water from the Pueblo Reservoir. The hands-on exhibits allowed kids to make snow, touch a cloud, shoot water from a fire hose, and learn more about how CSU uses water supplied by the SDS…

Forte said the Waterfest was designed to thank customers “for their patience” over the last couple of decades while the SDS became reality.

“Our citizen-owners have come out to see what we’ve been talking about for the last 20 years,” Forte said. “It’s just a fun day.”

The Grand River Ditch has an appropriation date of 1890 for 524.6 c.f.s of water diverted from the Colorado River Basin to irrigate 40,000 acres of land in the Poudre Basin through the Larimer County Ditch. The water flow of the ditch is continuously measured at this gauging station on La Poudre Pass.
