National Dam Inspection Program. SCS PA-476 (NDS-I.D. Number PA 00719, DER I.D. Number 6-456), Delaware River Basin, Tributary of Mill Creek, Berks County, Pennsylvania. Phase I Inspection Report,

Abstract

SCS PA 476 Dam is a 46-foot-high zoned-earth embankment about 400 feet long. The principal spillway consists of a concrete drop inlet riser, 182 feet of 24 inch reinforced concrete pipe with six anti-seep collars, and an impact basin. The reservoir drain is a 12-inch corrugated metal pipe. The dam and its appurtenant facilities are considered to be in good condition. Calculations indicate that the existing spillway systems are capable of passing the Probable Maximum Flood (PMF) without overtopping. Therefore, the spillway system is considered to be adequate.
