Englishtown Lake Dam is an earth embankment approximately 48 feet wide at the crest, 13 feet high and 325 feet long. County Route 527 is located on the crest of the dam embankment. The upstream slope of the embankment is retained by a creosoted timber bulkhead, while the downstream face of the dam is constructed on a slope of about 2.5H:1V. A concrete gravity spillway about 45 feet long is located approximately 60 feet from the right abutment. Spillway discharge passes under a bridge to the natural downstream channel. A four-foot diameter reservoir drain is located at the right side of the spillway. Based on visual observations made during the inspection, information provided by the New Jersey Department of Environmental Protection (NJDEP), and conversations with local residents, Englishtown Lake Dam is considered to be in poor overall condition. The spillway is capable of passing five percent of the PMF prior to overtopping the embankment.
