<br />Provo River flows through the critical 4.9 mile reach of habitat, conducted three years of study to <br /> <br />define flow needs, and has worked with water users to protect the flows and habitat. Upstream, <br /> <br />Reclamation has secured Provo River winter flows from Deer Creek Dam to protect the "blue- <br /> <br />ribbon" brown trout fishery during critical winter spawning periods. <br /> <br />Aspinal Unit and Gunnison River: An interim contract has been e)(ecuted to provide flows to <br /> <br />study and protect endangered fish species in the lower Gunnison River and to operate a fish <br /> <br />passage constructed in 1995-96 around the Redlands Diversion Dam. Reclamation is working on <br /> <br />long-term agreements to deliver water to the Black Canyon of the Gunnison National Monument <br /> <br />and to deliver water for endangered fish needs. Such a contract is an innovative way to protect <br /> <br />both environmental and water user's interests. Biologists have determined that endangered <br /> <br />Colorado squawfish can spawn successfully in the Gunnison River upstream of Red lands <br /> <br />Diversion Dam, leading to a belief that the combination of changed flows and the fish ladder will <br /> <br />contribute to increased natural reproduction. <br /> <br />McPhee Dam and Dolores River: The construction of McPhee Dam and subsequent reservoir <br /> <br />operation created a "blue-ribbon" trout fishery in a river that seasonally used to run dry. <br /> <br /> <br />Reclamation has worked with the Dolores Water Conservancy District to provide 3,900 acre-feet <br /> <br /> <br />of water for downstream fish and wildlife. Reclamation has leased 3,300 acre feet of unused tribal <br /> <br /> <br />irrigation water for five years or until such time as it is needed from the Ute Mountain Ute Tribe <br /> <br />for downstream fish and wildlife purposes. <br /> <br />Navajo Dam and San Juan River: Reclamation has conducted two low-flow tests of winter <br /> <br />flows from Navajo Dam to simulate historic conditions. These tests are requirements of the <br /> <br /> <br />Reasonable and Prudent Alternative in the Final Biological Opinion for the Animas-La Plata <br /> <br /> <br />Project. The first was a two-week study in 1996, and then a four-month study from November <br />
