The reservoir first impounded the water of Old Mill Stream and Red Clay Creek in 1932, with a dam built by the city of Wilmington, Delaware, for municipal drinking water. It has a water surface of 187 acres, a maximum capacity of 11,000 acre-feet, and a normal capacity of 6300 acre-feet.[1] The reservoir and its surroundings have been open to the public since 1971.[2] It is the largest reservoir in Delaware.
The dam, Edgar M. Hoopes Dam (National ID # DE00015), is a concrete gravity dam originally built in 1932 and restructured several times since. It is 135 feet high and 845 feet in length at the crest.[1] Its namesake, Edgar M. Hoopes, was Chief Engineer of the Wilmington Water Department from 1913 through 1918, according to a plaque on site.[2]
