Williams Fork Reservoir

A peaceful, secluded place to play

Completed in 1959, Williams Fork Dam and its power plant send water and electricity to the West Slope when Denver diverts water. Standing 217 feet above the Williams Fork River streambed, the dam backs up a reservoir of nearly 97,000 acre-feet of water, and the power plant contains a 3,158-kilowatt generator.
