National Dam Safety Program. Stark Lake Dam (MO 30516), Missouri - Kansas City Basin, Warren County, Missouri. Phase I Inspection Report
Based on the visual inspection and the results of these hydrologic/hydraulic investigations, the present general condition of the dam is considered to be satisfactory. Deficiencies were noticed during the inspection and are considered to have an adverse effect on the overall safety and future operation of the dam. Erosion of the grass covered upstream face of the dam apparently by wave action and/or fluctuations of the lake surface level has created a near vertical bank up to about 12 inches high above the normal waterline. A grass covered slope is not considered adequate protection to prevent erosion by wave action or fluctuations of the lake level. Loss of material due to erosion can impair the structural stability of the dam. Wire mesh type fencing is located across the upstream end of the spillway pipes. The fencing could act as a barrier upon which lake carried debris can lodge and prevent lake outflow from entering the spillway pipes. Blockage of the spillway pipes may result in excessive flooding of the lake and possible overtopping of the dam. Several holes believed to be old animal burros exist along the upstream face of the dam. Animal burrows can provide passageways for seepage that could develop into a piping condition (progressive internal erosion) resulting in failure of the dam.
