National Dam Inspection Program. Hemlock Lake Dam (NDI-PA 00399, PA DER 52-71), Delaware River Basin, Tributary Bush Kill Creek, Pike County, Pennsylvania. Phase I Inspection Report
Hemlock Lake Dam is an earth embankment with a concrete core wall. The embankment is about 625 feet long with a maximum height of approximately 14 feet. The top width of the dam is a minimum of 150 feet and the earth embankment side slopes are 3 horizontal to 1 vertical (3H:1V) both upstream and downstream. The top of the dam is used as a golf course fairway. A drop spillway, with a round crested weir, is located adjacent to the right (looking downstream) abutment. The crest of the weir is 3 feet below the top of the dam, and the length of the weir is 47 feet. The drop spillway is of stone masonry construction except for the rounded weir crest section which is poured concrete. The distance from the drop spillway weir crest to the apron is about 7 feet. The apron is 20 feet long and slopes down from each side wall. The transverse end sill is of negligible height at the side walls and is about 2 feet high in the center. Two 24-inch semi-circular corrugated steel pipes are constructed into the end sill and act as control structures. Flow passes over the drop spillway, through the two corrugated pipes, and into Lower Lake.
