Deer Creek Reservoir, reservoir in Wasatch County, Utah, United States

Deer Creek Reservoir is a water storage facility in Wasatch County, Utah, created by a dam that holds back water flowing through a scenic mountain valley. The lake extends for several miles with forested slopes and rocky ridges forming the surrounding landscape, offering views of varied terrain and natural vegetation.

Construction of the Deer Creek Dam began in May 1938 and was completed in 1941. The zoned earthfill dam, 235 feet high with a crest 1,304 feet long, is the key structure of the Provo River Project managed by the U.S. Bureau of Reclamation. It holds 2,810,000 cubic yards of material and creates a reservoir of 152,570 acre-feet capacity.

The reservoir lies on the Provo River about 16 miles northeast of Provo, reached by road through Provo Canyon. The water sits at 1,652 m, with Mount Timpanogos rising 14 km to the east. Boating, fishing, camping, swimming and water skiing take place on and around the water; the reservoir is the main feature of Deer Creek State Park.

The lake serves as a major recreation spot for residents from nearby Salt Lake City while remaining overlooked by many regional travelers. The valley setting has retained a wilder character compared to other reservoirs in the region, drawing those seeking quieter outdoor experiences.
