U.S. Army Garrison Fort Ritchie, Lower Lake Dam, Fort Ritchie Military Reservation, Cascade, Washington County, MD

Significance: This dam is the lower unit of a two part-water control system at Fort Ritchie, Maryland. Both dams are locally important structures used to maintain the recreational-use lakes at Fort Ritchie. Although this dam and the Upper Dam (HAER No. MD-104) replace the original dams built by the natural ice company that operated at this site prior to the establishment of Post in 1926, the current dams serve to maintain the two lakes in their pre-military appearance.
