National Dam Inspection Program. Rodebaugh Dam (NDI Number PA 00967, DER Number 15-273), Delaware River Basin, Tributary to Beaver Run. Chester County, Pennsylvania. Phase I Inspection Report
Rodebaugh Dam is an earthfill dam about 16 feet high and 235 feet long. The upstream slope above the water line averages about 2H:1V and is protected by riprap. The embankment crest is about six feet wide and protected by grass. Construction specifications indicate a stone masonry core wall under the dam centerline with a minimum base thickness of 3 feet, tapering to one-foot thick at the top. The downstream slope ranges from about 2.0H:1V to 3.2H1V and is covered with grass and weeds. A 20-foot wide stone masonry spillway is constructed near the right abutment. The pond drain is a 16-inch corrugated metal pipe encased in concrete located about 16 feet to the left of the spillway. Hydrologic and hydraulic computations indicate that the spillway structure is not capable of discharging the 100 Year Event without overtopping the embankment by about one-half foot for more than 1.0 hour. The structure is considered to have an 'Inadequate' spillway as it will not pass the spillway design flood without overtopping the embankment. If the embankment crest were raised to its design elevation, the spillway would be considered 'Adequate'.
