Facts & Figures


Ruedi Dam and Reservoir are U.S. Dept. of the Interior Bureau of Reclamation facilities. They were constructed 1964-68 by the Bureau as part of the Fryingpan-Arkansas project which developed transbasin diversions to transfer water from Colorado’s west slope to the front range. The Bureau continues to manage the Dam and Reservoir and the US Dept. of Agriculture Forest Service manages the adjacent lands.

The West Slope Collection System, located upstream of Ruedi Reservoir in the upper Fryingpan River and Hunter Creek watersheds, is a series of 16 stream diversion structures and eight tunnels. The system collects spring snowmelt runoff by gravity and directs it to the Boustead Tunnel. The Boustead Tunnel conveys water collected by the West Slope Collection System under the Continental Divide and into Turquoise Lake on the East Slope. The tunnel is five miles long and has a water conveyance capacity of 945 cubic feet per second (ft/s). Eight percent of the water in the Watershed is currently diverted to the Eastern Slope.
