Ruedi Reservoir, Protected reservoir in White River National Forest, Colorado, United States

Ruedi Reservoir is a reservoir on the Fryingpan River, about 15 miles upstream of Basalt, Colorado, straddling the Pitkin and Eagle county line in White River National Forest. It lies at 2,363 metres (about 7,750 feet) and covers roughly 3.7 square kilometres, stretching about 6.8 km east to west and 1.9 km north to south. Ruedi Dam, at its west end, is in Eagle County.

Ruedi Dam and the reservoir were built between 1964 and 1968 by the United States Bureau of Reclamation as part of the Fryingpan-Arkansas Project. The reservoir was created to compensate for East Slope diversions higher in the Fryingpan Basin and to supply West Slope water users. The dam stands in Eagle County, while the reservoir straddles the Pitkin-Eagle county line.

Ruedi Reservoir draws fishing enthusiasts throughout the season, and the water fills with small boats on weekends. The surrounding forest trails attract campers and day visitors who come to walk along the shoreline.

The reservoir is open for boating and fishing during the warmer months, and all watercraft must pass an inspection before launching. Trails along the shoreline are easy to follow and work well for walkers of most fitness levels.

A small power plant at the base of the dam quietly generates electricity using water released from the reservoir, something most visitors walk past without noticing. The reservoir is also part of a tunnel system that moves water under the mountains to the drier side of the Divide.
