The earthen dam was completed by the United States Bureau of Reclamation in May 1950, impounding the Heart River. The dam has a structural height of 65 feet and is 2275 feet along its crest. The dam was expanded in 1981, and an auxiliary spillway with bascule gates added.
The dam creates the Dickinson Reservoir, renamed Edward Arthur Patterson Lake in 1959. The reservoir holds 8612 acre-feet of water, used for agricultural irrigation, flood control, and for Dickinson's municipal needs. No hydroelectric power is generated here. The lake covers about 1,190 surface acres and 22 miles of shoreline. Recreation available at the lake includes camping, fishing and boating.
