National Dam Safety Program. Siegmund Lake Dam (MO-30520), Missouri - Kansas City Basin. Warren County, Missouri. Phase I Inspection Report.
Abstract
The following summarizes the findings of the visual inspection and the results of certain hydrologic/hydraulic investigations performed under the direction of the inspection team. Based on the visual inspection and the results of the hydrologic/hydraulic investigations, the present general condition of te dam is considered to be less than satisfactory. Several items were noticed during the inspection which are considered to have an adverse effect on the overall safety and future operation of the dam. These items, which are considered to be deficiencies, include deterioration of the upstream face of the embankment, the lack of adequate turf cover on the crest and certain areas of the upstream and downstream faces of the dam as well as the lack of suitable form of protection, such as riprap, to prevent erosion of the upstream face by wave action or by fluctuations of the lake level, subsidence of the dam at what appeared to be a collapsed animal burrow, seepage near the toe of the embankment in the original valley fill, erosion of areas adjacent to the downstream toe of the dam, and the presence of trees on the downstream face of the dam. Results of a hydrologic/hydraulic analysis indicated that the spillway is inadequate to pass lake outflow resulting from a storm of PMF magnitude without overtopping the dam.
