National Dam Inspection Program. Trinity Church Dam (Gilbert Run Watershed - Site Number 1), (NDI-ID Number MD-37) Potomac River Basin, Gilbert Run, Charles County, Maryland. Phase I Inspection Report
Trinity Church Dam was constructed as a zoned earthfill structure. The dam is approximately 1,690 ft. in length, has a maximum toe to crest height of 40 ft., and a crest width of 15 ft. Upstream and downstream slopes have inclinations of 3H:1V and 2.5H:1V, respectively. A 10 ft. wide bench is located on the upstream slope at normal pool level (El. 75.0). According to as-built drawings seepage control provisions include a 1,500 ft. long cutoff trench constructed near the toe of the upstream slope and a 1,360 ft. long filter trench located approximately 70 ft. downstream from the dam crest. Seepage, intercepted by the filter trench, is diverted to the outlet pipe plunge pool by means of perforated corrugated metal pipes and a blanket drain.
