Cherry Creek Dam
Cherry Creek Dam is a dam in Arapahoe County, Colorado, southeast of Denver.
The earthen dam was constructed between 1948 and 1950 by the United States Army Corps of Engineers with a height of and a length of at its crest. It impounds Cherry Creek, a tributary of the South Platte River, for flood control. The dam and reservoir are owned and operated by the Corps of Engineers. The dam is located on Cherry Creek at its confluence with Cottonwood Creek and consists of an earthen embankment, an outlet structure for releasing stored water, and a spillway through which excess water can flow into the adjacent Toll Gate and Sand Creek drainage basins during times of extreme water levels.

The Cherry Creek Dam outlet manages reservoir levels by releasing water from the reservoir into Cherry Creek to downstream users. Release rates are generally less than 100 cubic feet of water per second. One cubic foot of water, or cfs, is equivalent to 7.5 gallons. The outlet structure can release water at a rate of up to 10,000 cfs. when operating to reduce flood risks during periods of high runoff. In addition, the spillway is designed to additionally pass up to 45,000 cfs into Toll Gate Creek on to Sand Creek and ultimately into the Platte River.
The reservoir it creates, Cherry Creek Reservoir, has a water surface of, and a maximum capacity of. Recreation at the reservoir centers on the facilities of the adjacent Cherry Creek State Park, which offers camping, radio-controlled aircraft, picnicking, opportunities for bird watching, cross country skiing, fishing, horseback riding and an outdoor shooting range.
