National Dam Inspection Program. Deer Valley Lake Dam (NDS I.D. Number PA-00230, PennDer I.D. Number 56-76), Ohio River Basin, Cove Run, Somerset County, Pennsylvania. Phase I Inspection Report,
Abstract
Based on a visual inspection, operational history, and available engineering data, the dam is considered to be in fair condition. Structural deficiencies noted during the inspection include an inoperable drawdown mechanism, seepage and ponded conditions at the downstream toe, dense overgrowth (bushes, weeds, small trees) on the down stream slope, and minor concrete deterioration in the spillway. The size classification of the facility is intermediate and its hazard classification is considered to be significant. In accordance with recommended guidelines, the Spillway Design Flood (SDF) for this facility is 1/2 the Probable Maximum Flood (PMF). Results of the hydrologic and hydraulic analysis indicate that the facility can accommodate approximately 32 percent of the PMF and/or 64 percent of SDF (1/2 PMF). Thus, the spillway system is considered inadequate, but not seriously inadequate.
