The Uinta Basin Replacement Project, which was authorized by the Central Utah Project Completion Act, is located within Duchesne County near the towns of Altamont, Upalco, and Roosevelt, within the Uinta Basin of northeastern Utah. The Central Utah Water Conservancy District (District) is implementing the project. The Mitigation Commission is responsible for mitigating project impacts to fish, wildlife and wetland habitats. Funding for mitigation measures is provided under Title II of CUPCA through the U.S. Department of the Interior. The final Environmental Assessment was signed in October 2001 and project construction began in 2003.

The Projectís purpose is to provide additional early and late season irrigation water, provide municipal and industrial water supplies, and to modify and operate water management facilities for environmental purposes. This involves stabilizing thirteen high mountain lakes within the High Uintas Wilderness Area, constructing the new Big Sand Wash Feeder Diversion Structure and Pipeline, enlarging Big Sand Wash Reservoir, constructing a new Big Sand Wash-to-Roosevelt Pipeline, modifying the Moon Lake outlet works, and fish and wildlife mitigation and enhancement. Environmental needs include fishery resources that are depressed by widely fluctuating streamflows, dry damming, and recurring instream activities such as rebuilding irrigation diversions, channelization, and bank stabilization.

The Mitigation Commission issued a Decision Notice and Finding of No Significant Impact in February 2004 for implementing the fish and wildlife mitigation features of the Uinta Basin Replacement Project. The mitigation features are as follows:

  • Moon Lake Outlet Works Modifications. Minor modifications were made to the Moon Lake Dam outlet works to facilitate release of instream flows. (Under the previous operation, no water was released from Moon Lake Dam from October to April.)
  • Habitat Mitigation and Monitoring. The Mitigation Commission is responsible for wetlands mitigation and long-term maintenance and monitoring of the mitigation site. Wetlands mitigation for the project was implemented at the Montes Creek Wildlife Management Area through riparian wetland enhancement by Russian olive tree removal and controlling noxious and invasive weeds; wetland restoration by filling drainage ditches; and, new emergent wetland development by converting existing upland to emergent wetland. Montes Creek Mitigation Site As-Built Report, August 2010 summarizes activities completed at the mitigation site.
