"The proposed project would consist of the following: (1) An upper reservoir formed by a 160-foot-high by 6,750-foot-long, roller- compacted concrete (RCC) dam (an open ``U''--shaped structure varying from grade to roughly 160-foot-high) having a total storage capacity of 5,530 acre-feet and a water surface area of 90 acres at full pool elevation of 6,000 feet above mean-sea-level (msl); (2) a lower reservoir formed by a 200-foot-high by 730-foot-long, RCC dam, having a total storage capacity of 5,530 acre-feet and a water surface area of 110 acres at full pool elevation of 4,200 feet msl; (3) two 8,510-foot- long by 16-foot-diameter penstocks; (4) an underground powerhouse roughly 750-feet-long by 175-feet-high by 70-feet-wide; (5) two 320- foot-long by two 18-foot diameter tailraces; (6) an access tunnel roughly 36-feet-in-diameter and 2,470-feet-long, connecting the project's powerhouse to Grand County Highway 279; (7) the existing trail-road relocated to the south side of the reservoir to an elevation of 4,210 feet msl; and (8) pump-turbines with a capacity of roughly 800 megawatts (MW) (3 units x 267 MW unit). The annual energy output would be approximately 1,077,000 megawatthours. Twin 25--kilovolt (kV) circuit transmission lines would interconnect with an existing Rocky Mountain Power transmission line via a 40-mile-long interconnection."
