National Dam Safety Program. Smitty's Catfish Pond Dam (MO 30613), Mississippi - Kaskaskia - St. Louis Basin, Madison County, Missouri. Phase I Inspection Report
Smitty's Catfish Pond Dam is an earth dam impounding a lake used for recreational purposes. The embankment is constructed of locally-obtained, rocky, silty and clayey soil. The spillway is a vertical concrete wall near the maximum section. The downstream channel flows out of a small stilling pool at the toe of the spillway directly into the natural streambed for Greasy Creek. No control structures are present at this spillway. The results of the visual inspection indicate the dam is in generally poor condition. A small slump with a volume of 2 to 3 cu yd was noted on the downstream slope of the dam. This appeared to be a recent feature. The downstream slope is quite steep, generally 1.8(H) to 1(V), but is locally steeper than 1(H) to 1(V), and is judged to be only marginally stable. Animal burrows, to 8-in. in diameter, were noted at several locations on the downstream slope. Trees growing on the embankment could provide piping paths through the dam. Hydraulic and hydrologic analyses indicate the dam will be overtopped by a flood greater than 23 percent of the Probable Maximum Flood (PMF).
