National Dam Inspection Program. Wangaum Falls Dam (NDI Number PA-00141 DER Number 64-102), Delaware River Basin, Wayne County, Pennsylvania. Phase I Inspection Report
Wangaum Falls Dam is an earthfill dam with an embankment length of 310 feet and a maximum fill height of 30 feet. The structure has two spillways. One at the left abutment, which is the old spillway, has been reconstructed and raised several times. The second spillway was added in 1956 and is located in the right abutment. Both spillways have a bridge for vehicle access to a home on the right bank of the reservoir. The left spillway has a vertical slot closed off with vertical boards (stoplogs). Removal of these boards could lower the reservoir to about 7 feet below spillway weir elevation. There are no other drawdown or control facilities for this dam. Heavy riprap protects the upstream slope and a stoned surface roadway is on top of the embankment. The embankment was breached several times by floods prior to the reconstruction in 1956. Based on the visual inspection, past performance and the available engineering data, the dam and its appurtenant structures appear to be in fair condition. The spillway capacity is inadequate to pass the PMF peak inflow without overtopping the dam. The dam is capable of passing 70 percent of the PMF, and is considered to be inadequate, but not seriously inadequate.
