The lake has a total capacity of 3,100 acre-feet and controls the discharge <br />of Estes Powerplant, river inflow, river outflow, and releases of water to the Foothills Power <br />System via Olympus Tunnel (550 ft'/s capacity). The Estes Powerplant contains three units <br />with a total installed capacity of 45 megawatts, with combined release capability of 1,300 ft'/s. <br />The spillway, located on the right abutment, has five radial gates with a total release capability <br />of2l,200 ft'/s. The center gate has been automated and is controllable from the Loveland <br />Control Center. <br /> <br />During the winter, project water is diverted through Adams and Olympus Tunnels and routed <br />through the Foothills Power System on its joumey to terminal storage in Carter Lake and <br />Horsetooth Reservoir. <br /> <br />The October-January precipitation for the Big Thompson River Basin above Lake Estes was <br />, elJ ..et!lt 242 percent of average, with January precipitation ~ percent of average.
