The earthen dam was constructed between 1938 and 1941 by the United States Bureau of Indian Affairs using labor of the Civilian Conservation Corps and the Public Works Administration.[1] The structure has a height of 80 feet and a length of 2600 feet at its crest.[2] It impounds White Clay Creek for irrigation storage. The dam is owned and operated by the Oglala Sioux Tribe.
The reservoir it creates, Oglala Lake, has a normal water surface of 643 acres and has a maximum capacity of 18,300 acre-feet.[2] As a development project, even after significant government subsidies, the dam has been "a dismal failure from the year of its construction."[1]
The Oglala Sioux Tribe website reports 3 to 4 "seasonal openings each year." The [Safety of Dams] Program monitors the Dam's water levels and flows for early detection of major dam breach/breaks or severe flood emergencies."[3]
