Based on the criteria in guidelines, 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. Three to four farmhouses with associated farm buildings, three County roads, and one unimproved road would be subjected to flooding with possible damage and/or destruction, and possible loss of life. Monroe City Dam is in the intermediate size classification since it is more than 40 feet, but less than 100 feet high and impounds more than 1,000 acre-feet of water. Inspection and evaluation indicates that the spillway of Monroe City Dam meets the criteria set forth in the guidelines for a dam having the above size and hazard potential. Monroe City Dam is an intermediate size dam with a high hazard potential required by the guidelines to pass the Probable Maximum Flood without overtopping. It was determined that the spillway will pass 67 percent of the Probable Maximum Flood without overtopping the dam. Also, our evaluation indicates that the spillway will pass the 100-year flood; that is, a flood having a 1 percent chance of being equalled or exceeded in any given year.
