National Dam Inspection Program. Hosensack Number 4 Dam (NDI ID PA 00786, PA DER 39-4), Delaware River Basin, Indian Creek, Pennsylvania. Phase I Inspection Report,
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.
