Englewood Dam was constructed as a Works Progress Administration project in 1936. It is located on Willow Creek approximately 9 mi (14 km) upstream from Englewood in Arapahoe County, Colorado, United States. The project serves as a flood retention dam to control of about 11 sq mi (28 km2) of the 11 sq mi (28 km2) drainage area of the Little Dry Creek basin. Storage capacity is approximately 1,485 acre⋅ft (1,832,000 m3) at the spillway crest but the reservoir is dry most of the year.
