About Stagecoach Reservoir

Stagecoach Dam & Reservoir was conceived in 1983 by the Board of the Upper Yampa Water Conservancy District and designed to provide a reliable source of water for the growing population and economy of Northwest Colorado. This dam was constructed using a “new” (at-that-time) method of construction called Roller Compacted Concrete (RCC). Stagecoach Dam was only the 10th such RCC dam constructed in North America. The dam structure was built in 37 days working around the clock, by ASI-RCC, Inc. of Buena Vista, Colorado. The Stagecoach Dam & Reservoir was dedicated on August 12, 1989.

The reservoir provides stored water for agricultural irrigation, municipal and industrial contracts and environmental releases that help bolster flows in the river during hot and dry summer months. An 800kW hydropower plant located at Stagecoach Dam also generates enough electricity to power approximately 100 homes in the Yampa Valley each year. Stagecoach Reservoir is also a popular recreation spot for locals and visitors alike. The reservoir serves communities throughout the Yampa River Basin as a multi- purpose conservation reservoir. Recreation at Stagecoach Reservoir is managed by the Colorado Division of Parks and Wildlife.
