National Dam Safety Program. Goessling Dam (MO 30852), Missouri - Kansas City Basin, St. Louis County, Missouri. Phase I Inspection Report.
Abstract
The dam is an earth structure built prior to 1961 in the rolling topography on a tributary of Augusta Tavern Creek. There is an emergency spillway at the west abutment of the dam, an earth channel excavated in virgin soil. Our inspection and evaluation indicates that the dam is deficient in that the spillway is inadequate. Considering the small volume of water impounded, the large floodplain downstream and the three groups of farm buildings downstream, one-half Probable Maximum Flood (PMF) is the appropriate spillway design flood. A 20% PMF will begin to overtop the dam. The lake and spillway are adequate to contain a 100-year flood, which is a flood that has a 1% chance of being equalled or exceeded in any given year. Other deficiencies noted by the inspection team were tree growth on the upstram and downstream slopes of the dam and lack of erosion protection on the upstream slope and in the spillway of the dam.
