National Dam Inspection Program. Hallowood Lake Dam. Delaware River Basin, Long Run, Monroe County, Pennsylvania (NDI ID Number PA-00730, DER ID Number 45-194), Hallowood Homes Association, Inc. Phase I Inspection Report,

Hallowood Lake Dam is a homogeneous, earthfill embankment. It is 31 feet high at its maximum section and 595 feet long. The spillway is located at the right abutment. The spillway consists of an approach channel, a concrete weir, an outlet channel, and a stilling basin. The crest length of the spillway is 55.0 feet. Based on visual inspection, available records, calculations, past operational performance, and according to criteria established for these studies, Hallowood Lake Dam is judged to be in good condition. The spillway will pass about 82 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. No stability problems were evident for the embankment or the appurtenant structures at the time of the visual inspection. The ability of the outlet works to function is unknown because it has not been recently operated. Maintenance of the dam and appurtenant structures is considered inadequate.
