The Animas-La Plata Project (A-LP) is a water project that was planned and constructed to fulfill the water rights of the two Indian tribes that are federally recognized within Colorado – the Ute Mountain Ute and the Southern Ute tribes.

Completed in 2010, the A-LP is a large water project built by the Bureau of Reclamation south of the town of Durango, Colorado. The water project consists of a pumping plant on the Animas River located just south of the town, a conveyance pipeline and a 120,000 acre-foot reservoir (aka Lake Nighthorse). The CWCB purchased a portion of the water on behalf of the State of Colorado for approximately $35 million and is a member of the Animas La Plata Operations, Maintenance & Replacement Association (ALPOMR) Management Committee. The CWCB conducted a study to explore the water supply, demand and marketability of the water, compact issues, exchange potential, O&M costs, funding options and other applicable issues. The CWCB is currently under contract to sell a portion of the water to the La Plata Archuleta Water District.

The CWCB has partnered with the U.S. Army Corps of Engineers on two reallocation projects; the Chatfield Reallocation Project, and the Bear Creek Lake Reallocation Project. Both projects are in the Metro and South Platte Basins, and provide additional storage for various beneficial uses.

Chatfield Reallocation Project

The Chatfield Reservoir Reallocation Project came about as the result of a growing demand for water in Colorado’s Front Range and on northeast Colorado farms. The U.S. Army Corps of Engineers (Corps) determined Chatfield Reservoir can accommodate an additional 20,600 acre feet of water storage for water supply without compromising its flood control function. This additional storage space will be used by municipal and agricultural water providers to help meet the diverse needs of the state.

Please see the short video for an overview of the project.

Bear Creek Lake Reallocation Project

The Bear Creek Lake Reallocation Project is still in the Feasibility Study Phase. The Army Corps of Engineers approached the CWCB with a Reconnaissance Study in 2015 that showed potential to reallocate 20,000 acre feet of storage space for multiple uses. 

Currently, a scope of work is being developed for the Bear Creek Lake Reallocation Feasibility Study. 

The Army Corps of Engineers is accepting public comment throughout the study process. Please mail or email all public comment to:
