Stagecoach Dam

Stagecoach Dam is a gravity dam on the Yampa River in Routt County, Colorado, located about 20 mi south of Steamboat Springs. Built of roller-compacted concrete, the dam is 145 ft high and 360 ft long. The impounded water forms Stagecoach Reservoir, with a storage capacity of 33700 acre feet and a surface area of 780 acre at maximum pool. The dam serves for irrigation, municipal water supply, and flood control, and it also supports a hydroelectric power station with a capacity of 800 kilowatts.

First proposed in 1983, the dam was completed on August 12, 1989, after just 37 days of construction. The dam and reservoir are owned and operated by the Upper Yampa Water Conservancy District.
