Abstract:

Based on criteria set forth in the Recommended Guidelines for Safety Inspection of Dam, the dam is in the high hazard potential classification, which means that loss of life and appreciable property loss could occur in the event of failure of the dam. Perry City Dam is in the small size classification since it is less than 40 feet high and impounds less than 1,000 acre-feet of water. This inspection and evaluation indicates that the spillway of Perry City Dam does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. It was determined that the spillway will pass 41 percent of the Probable Maximum Flood without overtopping the dam. The evaluation indicates that the spillway will pass the 100-year flood.
