Owned and operated by the Denver Water Board, the Williams Fork Dam & Power Plant was constructed to provide mitigation to west slope water users whenever Denver diverts water during periods of downstream senior river calls and stores the water in Dillon Reservoir or water is diverted from the Williams Fork and Fraser River collection system for delivery through the Moffat Tunnel. The water stored in Dillon Reservoir is ultimately delivered to the City of Denver through the Roberts Tunnel. The Williams Fork Dam is a concrete arch that stands 27 feet above the Williams Fork River streambed and can store nearly 97,000 acre-feet of water. Williams Fork Reservoir’s surface area is 1,860 acres with a shoreline of 15.8 miles. Releases made from Williams Fork run through a 3.65 mega-watt hydroelectric power plant at the foot of the dam. The dam is located southwest of the town of Parshall, Colorado on the Williams Fork River about three miles above the confluence of the Williams Fork River with the Colorado River.
