Reclamation Signs Record of Decision for Windy Gap Firming Project in North Central Colorado

Here’s the release from Reclamation (Tyler Johnson):

Today, the Bureau of Reclamation’s Great Plains Regional Director Michael J. Ryan signed the Record of Decision, contract and associated documents, for the Windy Gap Firming Project, located southwest of Loveland, Colo.

“The Windy Gap Firming Project is an exceptional example of the federal government working with our partners to get big things done,” said Ryan. “This project represents an immense effort from a diverse group of stakeholders who pulled together and created a workable project that provides benefits to the people of Colorado and the nation.”

The signing of the ROD culminates a years-long effort by multiple water providers to increase the reliability of, or “firm,” the Windy Gap Project water supply, increasing reliable annual yield from zero to approximately 26,000 acre-feet.

“This is an important milestone for the Windy Gap Participants who have worked tirelessly over many years to make today a reality,” said Eric Wilkinson, General Manager for the Northern Colorado Water Conservancy District. “Today the development and construction of the Windy Gap Firming Project is one very significant step closer to reality. Thanks go out to all those who negotiated in good faith over the last several years to develop a number of agreements that form the foundation for the documents being signed today.”

The project potentially entails construction of a 90,000 acre-foot water storage reservoir, Chimney Hollow, south of Flatiron Reservoir on the East Slope, to provide more reliable water deliveries to Colorado’s Front Range communities and industry. The construction of Chimney Hollow Reservoir will also provide additional recreational opportunities that would be developed and managed by Larimer County.

“The process outcome is what all future water projects should be based on,” the Grand County Commissioners said in a statement. “We believe that consultation with Grand County during the 2014 contract negotiations is an indication of Reclamation’s commitment to open decision-making on matters involving operations of the Colorado-Big Thompson Project.”

Reclamation, along with Northern Water Conservancy District and Northern Water’s Municipal Subdistrict, have negotiated a contract allowing the Subdistrict to use excess, or unused, capacity in Reclamation’s Colorado-Big Thompson Project for Windy Gap Project water. New connections between Chimney Hollow Reservoir and C-BT Project facilities would allow water delivery to participants using existing C-BT infrastructure. Colorado-Big Thompson Project water would also be “prepositioned” in the Subdistrict’s Chimney Hollow Reservoir to help improve the reliability of Windy Gap Project water deliveries. Total allowable C-BT Project storage or yield would not change. The estimated total construction cost for Chimney Hollow Reservoir and associated facilities is $223 million (in 2005 dollars) for the dam, reservoir, appurtenances and conveyance facilities. It is estimated that Chimney Hollow could be operational in five to seven years.

Here’s the release from Northern Water (Brian Werner):

The Windy Gap Firming Project received its Record of Decision Dec. 19, 2014, during a signing ceremony at Northern Water’s headquarters in Berthoud. Mike Ryan, Great Plains Regional Director for the U.S. Bureau of Reclamation, signed the firming project’s long- anticipated ROD.

Officials from Northern Water, Northern Water’s Municipal Subdistrict and Reclamation also signed a new Carriage Contract allowing Windy Gap water to be transported from the West Slope to Chimney Hollow Reservoir using existing Colorado-Big Thompson Project facilities.

The ROD identifies and confirms Chimney Hollow Reservoir as the firming project’s preferred alternative. If built as proposed, Chimney Hollow Reservoir would store up to 90,000 acre-feet of water southwest of Loveland and just west of Carter Lake.

“Signing the Record of Decision and new Carriage Contract is a major milestone for the project,” said Jeff Drager, Project Manager for the Windy Gap Firming Project. “With Chimney Hollow Reservoir, the Windy Gap Firming Project will be able to provide 26,000 acre-feet of water year in and year out to growing communities in Northeastern Colorado.”
Dennis Yanchunas, President of Northern Water’s Municipal Subdistrict, applauded the participants’ perseverance. “While this has taken a number of years, it is worth the effort as Chimney Hollow Reservoir is that much closer to reality.”

The Windy Gap Firming Project is a collaboration of 12 Northeastern Colorado water providers and Platte River Power Authority to improve the reliability of their Windy Gap water supplies. Windy Gap began delivering water in 1985.

The participants include 10 municipalities: Broomfield, Erie, Evans, Fort Lupton, Greeley, Lafayette, Longmont, Louisville, Loveland and Superior; two water districts: Central Weld County and Little Thompson; and one power provider: Platte River.

The firming project’s federal permitting process began in 2003 under the National Environmental Policy Act. Reclamation issued a final Environmental Impact Statement in 2011 along with the Colorado Parks and Wildlife Commission’s approval of a fish and wildlife mitigation plan.

Construction of Chimney Hollow Reservoir could begin in 2018.

Northern Water’s Municipal Subdistrict is a separate and independent conservancy district formed by six municipalities in 1970 to build and operate the Windy Gap Project. The Windy Gap Project consists of a diversion dam and pump plant on the Colorado River, and a six-mile pipeline to Lake Granby.

Northern Water is a public agency created in 1937 to contract with Reclamation to build the Colorado-Big Thompson Project, which collects water on the West Slope and delivers it to the East Slope through a 13-mile tunnel beneath Rocky Mountain National Park. Northern Water’s boundaries encompass portions of eight counties, 640,000 irrigated acres and a population of about 880,000 people.
