National Dam Inspection Program. Storage Dam (NDI I.D. Number PA-388 DER I.D. Number 24-47), Ohio River Basin, Whetstone Branch of Little Toby Creek, Elk County, Pennsylvania. Phase I Inspection Report,

Storage Dam consists of an earth embankment approximately 500 feet long with a maximum height of 36 feet from the downstream toe and a crest width of approximately 15 feet. The appurtenant structures of the dam consist of a combined primary and emergency spillway located on the left abutment (looking downstream) and outlet works near the right abutment. Based on the evaluation of the existing conditions, the condition of Storage Dam is considered to be good. Numerous seeps were observed along the left abutment, but these seeps are not considered to be a threat to the integrity of the embankment. However, a slump and an associated wet area were observed along the toe of the dam near the left abutment. This condition should be investigated and necessary repairs performed. The flood discharge capacity of the Storage Dam spillway was evaluated according to the recommended procedure and it was found to be 40 percent of the probable maximum flood (PMF) without overtopping the embankment. Therefore, according to the recommended criteria, the flood discharge capacity of the dam is classified to be inadequate.
