National Dam Safety Program. N. J. No Name Dam Number 36 (NJ00532), Delaware River Basin, Trout Brook, Sussex County, New Jersey. Phase I Inspection Report.

Abstract

Abstract : The dam consists of an earth embankment with a principal spillway at the right end, emergency spillway at the left end and low level outlet near the center. The principal spillway consists of three 12-inch corrugated metal pipes transversely penetrating the embankment while the emergency spillway consists of a grassed channel adjacent to the end of the embankment. The outlet works consists of a low level 12-inch corrugated metal pipe with a gate valve located near its discharge end. The outlet discharges directly into Trout Brook which runs along the downstream toe of the dam. The crest and upstream face of the dam is stabilized by heavy grass cover while the downstream face is overgrown with trees and bushes. Based on visual inspection, available records, calculations and past operational performance, N.J. No Name No. 36 Dam, is judged to be in fair overall condition. The dam's spillways are considered inadequate because a flow equivalent to 30 percent of the One Hundred Year Flood would cause the dam to be overtopped.
