National Dam Safety Program. Sterling Lake Dam (NJ 00434), Delaware River Basin, Mantua Creek, Gloucester County, New Jersey. Phase I Inspection Report
Sterling Lake Dam is an ill-defined 150 foot long highway embankment structure with a bridged spillway. The spillway is a concrete arch weir 22 feet in length with a 2 foot x 2 foot wood gate in the center of the arch. Gloucester County Bridge No. 5-J-14 spans the 16 foot discharge opening. The two-lane asphalt Pitman-Downer Road (30 feet in width) runs along the dam crest. At the upstream face of the embankment are situated 3 foot high dikes with stone masonry walls keyed into the earth and supporting remnants of a boardwalk. The slopes of the downstream embankment vary between 1H:1V at the outlet to 3H:1V near the abutments. Sterling Lake Dam is assessed to be in a fair overall condition although the spillway should be further inspected and additional hydrological/hydraulic studies undertaken to ascertain what improvements can be made in view of the fact that the discharge culvert is almost completely submerged by the downstream lake. The capacity of the spillway will accommodate only 6% of the 1/2 PMF design flood but the dam is not assessed as UNSAFE, NON-EMERGENCY as collapse from overtopping could not increase the hazard to life downstream from the erstwhile condition prior to overtopping.
