National Dam Safety Program. Bethel Lake Dam (NJ00406), Delaware River Basin, Mantua Creek, Gloucester County, New Jersey. Phase I Inspection Report
The dam is an earth embankment supporting Gloucester County Highway Route 635 known as Lambs Road. The spillway structure consists of a horseshoe-shaped concrete weir located on the upstream side of the embankment. At the center of the embankment a concrete bridge forms the spillway discharge channel. The outlet works consists of a gated 2' x 2.5' sluice which transversely penetrates the center of the concrete spillway structure. The outlet discharges from the downstream face of the spillway structure into a stilling area between the spillway and bridge. Based on visual inspection, past operational performance and Phase I engineering analyses, Bethel Lake Dam is assessed as being in fair overall condition. Hydraulic and hydrologic analyses indicate that the spillway is inadequate. Discharge capacity of the spillway is not sufficient to pass the designated spillway design flood (100-year storm) without an overtopping of the dam. The spillway is capable of passing approximately 14 percent of the SDF.
