E <br /> <br />CHAPTER 1 <br />1 INTRODUCTION AND PURPOSE <br />1.1 PURPOSE <br />The purpose of this investigation is to summarize the results of a feasibility investigation of <br />19 alternatives to supply 20,000 acre-feet of water to the head of the 15-1\1ile Reach for purposes of <br />recovering four species of endangered fish in the Colorado River in Colorado. This investigation is in <br />response to the findings, conclusions and of recommendations of the Phase 1 report for this project, <br />' Phase 7 Coordinated Facilities WaterAvailability Study for the Endangered Fishes of the Upper Colorado River <br />(Colorado Water Conservation Board, September 2000). These 19 alternatives include: <br />' 1. Expanded Coordinated Reservoir Operations <br />¦ Alternative 1a: Green Mountain Reservoir reduced winter power operations. <br />¦ Alternative 1a: Green Mountain Reservoir conjunctive pool operations. <br />¦ Alternative 1 a: Preemptive release and water carried over in Green Mountain <br />Reservoir. <br />¦ Alternative 1b: Ruedi Reservoir modified operations. <br />¦ Alternative 1d: Modify Colorado-Big Thompson (CBI) west slope facilities <br />operations. <br />¦ Alternative 1e: Denver Water system modified operations. <br />' Alternative 1 f: Bypass diversions to storage. <br />¦ Alternative 1g. Reduce constraints on Coordinated Reservoir Operations <br />' (CROPS). <br />2. Efficiencies of Conveyance and Distribution Facilities <br />¦ Alternatives 3d and 3e investigated as components of 1a: Re-analysis of Grand <br />Valley Project (GVP) and analysis of Grand Valley Irrigation Company <br />' (GVIC) water management for additional efficiency as a component of <br />Alternative 1a, Green Mountain Reservoir operations. <br />3. New Storage Projects <br />¦ Alternatives 4f, 4g, 4k, 4n, and 4o: New tributary storage facilities below <br />Shoshone Power Plant. <br />' ¦ Alternative 4m: New mainstem storage facility. <br />4. Power Plant Operations and Scheduling <br />¦ Alternative 5a: East slope power operations and scheduling, investigated as a <br />component of Alternative 1d: CBT west slope facilities operations. <br />1 <br />PAData\GEN\CWCB\19665\Report Phase 2\FinalRepon9.03\Final_CFOPS_Report(9-03).doc 10
