National Dam Safety Program. Lake of the Hills Dam (MO 30077), Mississippi - Kaskaskia - St. Louis Basin, Bollinger County, Missouri. Phase I Inspection Report.
Abstract
The purpose of the inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life or property. This dam is classified as a small size dam with a high downstream hazard potential. Failure would threaten the life and property of 2 or more families downstream of the dam. The inspection and evaluation indicate that the spillway does not meet the criteria set forth in the guidelines for a dam having the above mentioned size and classification and hazard potential. For its size and hazard category, this dam is required by the guidelines to pass from one-half PMF to PMF. However, considering the high-hazard potential to life and property of two families downstream of the dam, the PMF is considered the appropriate spillway design flood. Other deficiencies visually observed by the inspection team were trees, bushes, and seepage on the downstream embankment slow and toe; erosion gullies and sloughing on the downstream embankment slope; minor wavewash on the upstream embankment slope; and undermining of the downstream ends of the primary and emergency discharge structures.
