National Dam Safety Program. Stergen Lake Dam, No Name 448 (MO 30606), Missouri - Kansas City Basin, St. Charles County, Missouri. Phase I Inspection Report.
Abstract
The dam is an earth structure built in the hilly ground at the west edge of the floodplain of Femme Osage Creek. Normal rainfall, runoff, transpiration, evaporation and seepage either through the dam abutments or the rock in the reservoir all combine to maintain a relatively stable water surface elevation. Our inspection and evaluation indicates the dam is deficient in that it has no spillway. The guidelines for a dam having the above size and hazard potential require that the spillway be capable of passing a Probable Maximum Flood (PMF). A PMF will overtop the dam to a maximum depth of 1.9 feet with a maximum flow of about 600 cubic feet per second. The dam is also deficient in that extensive and serious seepage through and under the dam embankment is occurring and there is erosion and possible sloughing on the downstream slope.
