National Dam Safety Program. Lake Barnegat Dam (NJ 00058), Atlantic Coast Basin, North Branch Forked River, Ocean County, New Jersey. Phase I Inspection Report.
Abstract
Lake Barnegat Dam is a 850 foot long earth embankment with a bridged drop inlet spillway. The spillway is a semi-circular concrete arch weir 50 feet in length, with a 3.5 inch deep by 12 foot wide depressed notch in the center of the 16 foot radius horseshoe arch. There are two 36 inch low level sluice gates in the spillway wall. The downstream embankment has a 2H:1V slope and is covered by trees and shrubs. The upstream embankment has 1H:1V slopes above normal pool. The asphalt-paved Lakeside Drive (30 feet wide) runs along the crest of the dam which contains a timber sheeting core wall along its entire length. Barnegat Lake Dam is assessed to be in a fair overall condition. Overtopping would not substantially increase the hazard to human life downstream but a collapse could endanger a downstream dam and Route 9 highway bridge. No detrimental findings were observed to render a hazardous assessment but additional hydraulic studies are recommended.
