National Dam Inspection Program. University of Maryland Baltimore County Dam (NDI-ID Number MD34), Chesapeake Bay Basin, West Branch of Herbert Run, Baltimore County, Phase I Inspection Report,

Abstract

The UMBC Dam was constructed as a zoned earthfill structure. The dam is approximately 255 ft. long, with a maximum toe to crest height of 41 ft. and a crest width of 20 ft. The principal spillway consists of a reinforced concrete entrance structure, a 259 ft. long 72 in. dia. reinforced concrete outlet pipe and a reinforced concrete impact stilling basin. The emergency spillway channel is excavated into natural earth is located at the left abutment. The spillway channel is approximately 150 ft. wide with a 30 ft. long level control section at the dam centerline. Review of available hydrologic/hydraulic design calculations indicate the emergency spillway can pass the PMF without overtopping the dam embankment. Therefore, spillway capacity is assessed as adequate, in accordance with recommended guideline criteria.
