National Dam Inspection Program. PA-468 Dam (NDI ID Number PA-00046, DER ID Number 58-132, SCS ID Number PA-468), Susquehanna River Basin, Brooklyn Run, Susquehanna County, Pennsylvania. Phase I Inspection Report,

Abstract

The purpose of the inspection is to determine if the dam constitutes a hazard to human life or property. The dam consists of a homogeneous earthfill embankment that is 680 feet long and 64 feet high at its maximum section. The main spillway is a drop spillway located near the left abutment of the dam. It consists of a concrete riser connected to a 30-inch diameter reinforced concrete pipe under the embankment. One 12-inch by 21-inch uncontrolled orifice is located in the upstream face of the concrete riser with the orifice crest at El. 1227.0, which is 27 feet below design elevation of the top of the dam. The auxiliary spillway is an excavated channel at the right abutment of the dam. It is grass-lined except for portions that were excavated into rock. The hazard classification is high hazard. Downstream conditions indicate that a high hazard classification is warranted for PA-468 Dam. It is owned by the Susquehanna County Commissioners. Its purpose is for flood control.
