National Dam Inspection Program. Sun Valley Dam (NDI Number PA-00998, DER Number 45-217), Delaware River Basin, Pohopoco Creek, Monroe County, Pennsylvania. Phase I Inspection Report
Abstract
Sun Valley Dam is owned by the Sun Valley Lake Corporation and is used for private recreational purposes. The spillway is in good condition and the embankment and emergency spillway are in poor condition. Internal piping may be acting to diminish the overall stability of the dam. In accordance with criteria established by Federal (OCE) Guidelines, the recommended spillway design flood for this 'Small' and 'Significant' hazard classification is the 100-year flood to one-half the Probable Maximum Flood. Based on the small capacity of the reservoir and the limited downstream development, the 100-year event has been selected as the spillway flood. Hydrologic and hydraulic computations indicate that the spillway structure is not capable of discharging the 100-year event. Thus, the spillway facilities of Sun Valley Dam are considered to be 'Inadequate'.
