EXECUTIVE SUMMARY <br />WINDY GAP FIRMING PROJECT DRAFT ENVIRONMENTAL IMPACT STATEMENT <br />• Alternative 2 (Proposed Action): Chimney Hollow Reservoir (90,000 AF) with prepositioning. <br />• Alternative 3: Chimney Hollow Reservoir (70,000 AF) and Jasper East Reservoir (20,000 AF). <br />• Alternative 4: Chimney Hollow Reservoir (70,000 AF) and Rockwell/Mueller Creek Reservoir <br />(20,000 AF). <br />• Alternative 5: Dry Creek Reservoir (60,000 AF) and Rockwell/Mueller Creek Reservoir <br />(30,000 AF). <br />Alternative 1 (No Action) <br />The No Action alternative defines what Participants would do if Reclamation does not approve a new <br />connection of WGFP facilities to C -BT facilities as required for the action alternatives. Under this <br />alternative, Participants would maximize delivery of Windy Gap water according to their demand, water <br />rights, availability of storage in Granby Reservoir, and existing Adams Tunnel conveyance constraints. The <br />City of Longmont would enlarge Ralph Price Reservoir by raising the dam and increasing storage capacity by <br />13,000 AF (Figure ES -3). Participants that do not have a currently defined storage option would take delivery <br />of Windy Gap water whenever it is available within the capacity of their existing water systems and delivery <br />points under the terms of the existing contract between Reclamation and the Subdistrict. Windy Gap <br />diversions will increase in the future regardless of whether one of the action alternatives is implemented <br />because of increased demand. <br />Figure ES -3.
