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

Significance: This dam is the upper 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 Lower Dam (HAER No. MD-105) 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.
Survey number: HAER MD-104
