Ridges Basin Dam

The Animas-La Plata Project located in La Plata and Montezuma Counties in southwestern Colorado and in San Juan County in northwestern New Mexico, was authorized by the Colorado River Basin Project Act of September 30, 1968 (Public Law 84-485).In 1988, it was incorporated into the Colorado Ute Indian Water Rights Settlement Act. The Colorado Ute Settlement Act Amendments of 2000 provide for implementation and completion of the project. Approval to begin construction was granted in October 2001 and initial site work began in April 2002.

Lake Nighthorse began filling on May 4, 2009, and filled for the first time on June 29, 2011. The maximum water surface elevation of 6,882 feet equates to 123,541 acre-feet in storage. The Colorado project features were transferred from construction status to operation and maintenance status in March 2013. Work on completion of the transfer stipulations is continuing. An operation and maintenance contract has been signed with the Animas-La Plata Operations, Maintenance and Replacement Association that allows project sponsors to operate Colorado project features.

Lake Nighthorse Recreation

Reclamation's Western Colorado Area Office is working with all Animas-La Plata Project partners and stakeholders to reach consensus regarding development and management of recreation at Lake Nighthorse. We believe we are nearing an agreement to integrate recreation into the project, while ensuring compatibility with the primary purposes of the project for municipal and industrial water supply. We are conducting regular meetings with partners and stakeholders to discuss and resolve a broad range of issues concerning water quality, environmental protection, and tribal trust responsibilities of the United States government. Many issues have been resolved and Reclamation continues to work on remaining issues, including working closely with Animas-La Plata Operation, Maintenance, and Replacement Association members to ensure protection of cultural resources and annexation of project lands by the city of Durango for administration of recreation and law enforcement purposes.
