National Dam Safety Program. Incline Village Lake Dam (MO 11041), Mississippi - Salt - Quincy River Basin, St. Charles County, Missouri. Phase I Inspection Report
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.
