National Dam Safety Program. Maple Lake Dam (NJ 00776), Passaic River Basin, Goffle Brook, Bergen County, New Jersey. Phase I Inspection Report.
Abstract
Maple Lake Dam is an earthfill and concrete dam, with a hydraulic height of 13.9 feet, a structural height of 14.5 feet, and a length of 290 feet. The dam has a concrete core wall that is visible the entire length of the dam. The dam crest is grass-covered and has an average width of 15 feet. The concrete spillway is 48 feet long, located approximately 91 feet from the road on the right overbank. The low-level outlet, probably a 12-inch pipe, leads from a valve box at the left upstream end of the spillway, through the dam, and along the left end of the stilling basin. Maple Lake Dam, a high hazard potential structure, is judged to be in poor overall condition. The dam's spillway is considered inadequate because a flow equivalent to 21 percent of the Spillway Design Flood would cause the dam to be overtopped.
