Abstract:

Hosensack No. 4 Dam is a masonry structure with an upstream embankment. The dam has a maximum height of about 32 feet and a length of 310 feet. A 175-foot long overflow spillway is located about 100 feet from the right abutment near the center of the structure and is capped with concrete in the masonry portion. A 24-inch diameter reinforced concrete drain pipe is located in the non-overflow portion of the dam about 3.5 feet left of the spillway section. Discharge through the pipe is controlled with stop planks in a drainage tower approximately 15 feet downstream from the intake. A review of the results of the hydrologic and hydraulic analyses indicates that the spillway is able to pass the Spillway Design Flood SDF without the dam being overtopped therefore, the spillway is considered Adequate. Based on visual observation and a review of the information obtained from the Pennsylvania Department of Environmental Resources, Hosensack No. 4 Dam appears to be in poor condition.
