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.

Perry City Dam No. 2 is located in Ralls County in the State of Missouri, and crosses the Mace Branch tributary of Lick Creek. The dam was constructed in 1964 to create an impoundment for additional water supply for the City of Perry, Missouri. The top of the dam and the upper exposed slopes of the embankment have a grass cover that adequately protects the embankment slopes have no riprap protection and are, consequently, eroded by wave action in the respective reservoirs. Nearly vertical faces up to 3 feet high are exposed. The dam has never been overtopped and no evidence indicating the contrary was observed. Both embankment slopes had large to intermediate-sized trees and bushes growing at or near the water surfaces. The left downstream abutment area inside of the emergency spillway area is low-lying and covered with tall grasses.

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.

The Lancaster City Dam is located near the headwaters of the North Fork of the Middle Fabius River. The main purpose of the dam is to impound water for recreational use and a supplemental water supply. The crest of the dam is protected against surface erosion by a cover of grass and clover. There was no evidence of significant settlement or cracking on the crest. No deviations in horizontal or vertical alignment were apparent. Some evidence of rodent activity was observed on the embankment. There was no evidence of the dam ever being overtopped. The upstream slope was protected by concrete rubble riprap to one foot above the water surface. Considerable erosion due to wave action above the riprap indicates the riprap might have been placed after construction of the dam. Scarps ranging from 1 to 3 feet high have been cut into the upper part of the upstream face. Several bushes and small trees were growing on the upper grass covered slope. No bulges or depressions in the slope were observed.

Based on the criteria in the 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 farmhouses with associated farm buildings, the Scotland County Fairgrounds and associated buildings, one highway bridge, and one improved road would be subjected to flooding with possible damage and/or destruction, and possible loss of life. Memphis Lake and Park 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 but less than 50,000 acre-feet of water. Our inspection and evaluation indicates that the spillway of Memphis Lake and Park Dam meets the criteria set forth in the guidelines for a dam having the above size and hazard potential. Memphis Lake and Park 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 greater than 100 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 during any given year.

Based on the criteria in the 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 farmhouses, one state highway, and one county road would be subjected to flooding, with possible damage and/or destruction, and possible loss of life. Wyaconda 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. Our inspection and evaluation indicates that the spillway of Wyaconda City Dam does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. Wyaconda City Dam is a small size dam with a high hazard potential required by the guidelines to pass from one-half Probable Maximum Flood to the Probable without overtopping. Since there is a relatively wide valley and little development downstream of the dam, one-half of the Probable Maximum Flood is the appropriate spillway design flood. It was determined that the spillway will pass 46 percent of the Probable Maximum Flood without overtopping the dam. Also, our evaluation indicates that the spillway will not pass the 100-year flood; that is, a flood having a 1 percent chance of being equalled or exceeded during any given year.
