Executive Summary <br />FEIS - Navajo Reservoir Operations <br />Alternatives Retained for Further Consideration <br />The following three alternatives were retained for further consideration. Their ability to <br />meet Flow Recommendations criteria is shown in figure S-4, and flow statistics are shown in <br />tables S-3 and S-4. <br />? No Action Alternative (Historical operation - from 1973 to 1991) <br />? 250/5000 Alternative (minimum release 250 cfs; maximum release 5,000 cfs) <br />? 500/5000 Alternative (minimum release 500 cfs; maximum release 5,000 cfs) <br />No Action Alternative <br />Because it does not address the Flow Recommendations, it is likely that implementing the <br />No Action Alternative would adversely affect downstream endangered fish habitat and <br />existing and future water development. However, this alternative would help maintain or <br />enhance the downstream trout fishery and river rafting by moderating flow fluctuations. <br />If no action is taken by Reclamation to operate Navajo Dam and Reservoir to meet the Flow <br />Recommendations criteria, future Indian water development in the Basin would probably <br />not proceed as planned, and several existing or proposed projects could be affected as well. <br />ESA consultations could be re-initiated on several projects such as the Animas-La Plata <br />Project, NIIP Blocks 7-11, Jicarilla Apache Nation third-party contracts, the Navajo-Gallup <br />Water Supply Project, and the Jicarilla Apache Nation Navajo River Water Supply Project. It <br />is uncertain whether the Service would issue favorable biological opinions on these projects <br />or any other Indian water development projects in the Basin. If the water supply available <br />from Navajo Reservoir is insufficient to meet additional future water uses pursuant to <br />Indian water rights, this could result in negative impacts to Tribal water development <br />projects and Tribal water uses. <br />Wildlife nesting areas on the San Juan River.
