National Dam Safety Program. Koenig Dam (MO 30028), Missouri - Kansas City Basin, St. Charles County, Missouri. Phase I Inspection Report.
Abstract
The dam is an earth structure built in the upper end of a (draw) in the hilly ground along the Missouri River on the fringes of the loess blown in from the river bottom. A spillway was cut into the earth slope on the northeast end of the dam. At some time, a concrete sill was constructed across the spillway channel about 20 feet downstream from the centerline of the dam apparently to control erosion of the spillway bottom. Our inspection and evaluation indicates that the spillway meets the criteria set forth in the guidelines for a dam having the above size and hazard potential. The principal spillway will pass a one-half Probable Maximum Flood without overtopping the dam. Our inspection and evaluation indicates heavy tree growth on both faces of the dam which could lead to conditions causing rupture of the dam. Other deficiencies were inadequate erosion protection of the upstream slope of the dam and spillway and lack of knowledge of the location and condition of a pipe reported to be under or through the dam.
