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.”

#Colorado Springs: “Sustainable stormwater funding and management is not optional” — John Suthers

coloradospringsstormwaterimplementationplan072016cover

Click here to read the plan.

Here’s the release from the City of Colorado Springs:

The City of Colorado Springs today released the draft Stormwater Program Improvement Plan designed to dramatically improve the city’s infrastructure and meet federal requirements.

City Public Works Director Travis Easton provided this statement.

“Today the City of Colorado Springs has released a draft Stormwater Improvement Plan. This is significant for our stormwater program, our citizens, and our City. The draft Stormwater Program Improvement Plan reflects strong leadership by the Mayor and City Council. We began this effort last fall and we reached a preliminary draft in January. Today’s release includes updates through July 2016.

“The City’s Public Works Department would appreciate the public’s comments and suggestions for improvement of the plan over the next 60 days. We will take public input into account and release the Plan in final form shortly thereafter.

“Thank you in advance for helping to shape this plan, and being a part of the process.”

Individuals wishing to provide feedback on the plan can contact Richard Mulledy, the City’s Stormwater Division Manager at stormwater@springsgov.com or by mail to: Richard Mulledy, Stormwater Division Manager, City of Colorado Springs, 30 S. Nevada Avenue, Suite 401, Colorado Springs, CO 80901.

The City of Colorado Springs and Colorado Springs Utilities have committed to investing a total of $460 million over 20 years, beginning this year. The commitments essentially replace the city Stormwater Enterprise that was defunded in 2009.

“Fixing the stormwater issues that we inherited stemming from the dissolution of the stormwater enterprise has been a top priority for me and the City Council,” said Colorado Springs Mayor John Suthers. “Sustainable stormwater funding and management is not optional – it is something that we must do to protect our waterways, serve our downstream neighbors, and meet the legal requirements of a federal permit.”

From The Pueblo Chieftain (Chris Woodka):

Colorado Springs this week released its draft stormwater plan, which was spurred earlier this year by negotiations with Pueblo County commissioners over permits for the Southern Delivery System.

The 305-page implementation plan mirrors the terms of an intergovernmental agreement, outlining at least $460 million in expenditures over the next 20 years and restructuring the city’s stormwater department. It was released Wednesday on the city’s website (http://coloradosprings.gov).

It’s important to Pueblo because work within Colorado Springs is expected to reduce damage along Fountain Creek.
Work already has started on some of the projects that are expected to benefit Pueblo County as well as Colorado Springs. A total of 61 of the 71 critical projects have downstream benefits to Pueblo and other communities, in a March assessment that included input from Wright Water Engineers, which has been hired by Pueblo County as consultant for Fountain Creek issues.

That list can change, depending on annual reviews of which work is needed, according to the IGA.

The plan also attempts to satisfy state and federal assessments that the existing stormwater services failed to meet minimum conditions of the city’s stormwater permits. An Environmental Protection Agency audit last year found Colorado Springs had made no progress on improving stormwater control in more than two years.

This year, Colorado Springs formed a new stormwater division and plans on doubling the size of its stormwater staff.

The plan includes a funding commitment of $20 million annually by the city and $3 million per year by Colorado Springs Utilities to upgrade creek crossings of utility lines.

The plan acknowledges that Colorado Springs significantly cut staff and failed to maintain adequate staffing levels after City Council eliminated the city’s stormwater enterprise in 2009. Pueblo County suffered significant damage, including the washout of part of Overton Road and excess debris in the Fountain Creek channel through Pueblo, during prolonged flows last May.

Other parts of the Pueblo County IGA expedited funding for flood control studies and projects by the Fountain Creek Watershed Flood Control and Greenway District, as well as providing an additional $3 million for dredging in Pueblo.

From The Pueblo Chieftain (Chris Woodka):

A hydropower project at Pueblo Dam has been given a green light by the Bureau of Reclamation and is in line for a $17.4 million state loan.

A finding of no significant impact was issued last week for the project being spearheaded by the Southeastern Colorado Water Conservancy District. Other partners in the project are Pueblo Water and Colorado Springs Utilities.

The Southeastern district will seek a $17.4 million loan for the project from the Colorado Water Conservation Board today. The loan would be for 30 years at 2 percent interest.

A 7 megawatt hydropower facility is anticipated at the north outlet works, which was constructed by Utilities as part of the Southern Delivery System.

“A hydropower plant and associated facilities will be constructed at the base of Pueblo Dam, utilize the dam’s north outlet works and immediately return flows to the Arkansas River downstream of the dam,” said Signe Snortland, area manager of Reclamation’s Eastern Colorado Area Office.

The next step will be negotiation of a lease of power privilege contract.

About 1.4 miles of new power and fiber optic lines also will be constructed to connect the hydropower plant to Black Hills Energy’s substation at Lake Pueblo.

Construction is expected to begin later this year, with the first power generation to begin in 2018.
