Kohl Irrigation Lake South Dam is located in Audrain County in the State of Missouri, and crosses an unnamed tributary of Shady Creek. As the name of the dam implies, the water impounded by the dam is used for crop irrigation. The crest and the downstream slope of the dam have a tall, dense grass cover, which adequately protects the embankment material from surface runoff erosion. However, the upstream slope has a sparse vegetative cover, and surface runoff has eroded small drainage rivulets on the order of 1 to 3 inches on the upstream face. The upstream slope also has no riprap protection and, consequently, has been eroded by wave action. Nearly vertical faces up to 2 feet high were exposed near the crest of the dam and smaller scallops were also exposed along the reservoir rim. The dam material underlying the grayish-brown topsoil cover was revealed to be a mottled red, brown, and gray, moderately plastic clay with some silt and sand. There was no evidence of seepage or leakage through or below the dam. No signs of past or present instability were seen on the embankment except for the wave eroded upstream slope.

The dams (the main dam and the check dam) are in significant hazard potential classification. Significant hazard potential category structures will be those located in predominantly rural or agricultural areas where failure may damage isolated homes, secondary highways or minor railroads or cause interruption of use or service of relatively important public utilities. The main dam is classified as small in the dam size category because its height is less than 40 feet, and it impounds less than 1,000 acre-feet of water. The check dam, which is three feet in height, forms a continuous barrier to the impoundment created by the main dam. The spillway of C & A Lake Dam does not meet the criteria set forth in the guidelines for dams having the above size and hazard potential. C & A Lake Dam being a small size dam with a significant hazard potential, is required by the guidelines to pass from 100-year to one-half of the Probable Maximum Flood without overtopping. Since there is significant hazard potential downstream of the dam and because of its location just upstream of a highway, the appropriate spillway design flood for C & A Lake Dam is one-half of the Probable Maximum Flood.

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.

The dam is a compacted earthfill structure between earth abutments. The top width is 35 feet for a distance of 150 feet to the right of the spillway while the remainder of the top of dam has been disguised by the dumping of fill material over the downstream face. The total length of the dam is 410 feet between the right abutment and the spillway. The spillway is an earthcut, uncontrolled, open channel and is cut into the left abutment of the dam. No low level outlets or outlet works were provided for this dam. The inspection and evaluation by the consultant's inspection team indicate that the spillway of Smith Lake 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 reservoir/spillway system can accommodate approximately 65 percent of the Probable Maximum Flood without overtopping the dam. The evaluation also indicates that the reservoir/spillway system can accommodate the one-percent chance flood (100-year flood) without overtopping.

The dam is a zoned, rolled, earthfill structure with a straight alignment between rock abutments. The top of dam width is 45 feet and the axis length of the crest of the embankment was measured as 856 feet. The maximum height of the dam was measured as 38 feet above creekbed elevation. The spillway serves as both an emergency spillway for larger flows and a principal spillway for the normal flows. The spillway crest and adjacent channel area were blasted out of rock just to the right of the right abutment. A low level drain consists of two 22 inch diameter welded steel pipes which pass through the embankment side by side. Each pipe is controlled at the downstream end by a 24 inch gate valve. The dam appears to be in satisfactory condition. However, several deficiencies were noted by the inspection team that could affect the safety of the dam. Our inspection and evaluation indicates that the spillway of Incline Village Lake Dam can accommodate approximately 60 percent of the Probable Maximum Flood without overtopping the dam. Our evaluation also indicates that the reservoir/spillway system can accommodate the one-percent chance flood without overtopping.

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.
