National Dam Safety Program. Cadet Number 2 Dam (MO 30707), Mississippi - Kaskaskia - St. Louis Basin, Washington County, Missouri. Phase I Inspection Report
Cadet No. 2 Dam, I.D. No. 30707 was inspected of the inspection was to assess the general condition of the dam with respect to safety. The assessment is based upon an evaluation of the available data, a visual inspection, and an evaluation of the hydrology and hydraulics of the site in order to determine if the dam poses hazards to human life or property. The dam provides impoundment for barite ore tailings. The results of the inspection and evaluation indicate that the dam does not meet the criteria given in the Guidelines for a dam with the size and hazard potential of Cadet No. 2 Dam. As an intermediate size dam with a high hazard potential, the Guidelines specify that the discharge capacity and/or storage capacity should be capable of safely handling the Probable Maximum Flood (PMF) without overtopping the crest. The PMF is the flood that may be expected from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the region. It has been calculated that the dam cannot handle a 100-year flood (a flood having a 1 percent chance of being equalled or exceeded in any 1 year) or a 10 year flood (a flood having a 10 percent chance of being equalled or exceeded in any year) without overtopping the dam. It was also estimated that the dam could retain 3 percent of the PMF without overtopping the dam and without significant erosion of the embankment; however, the dam cannot handle 50 percent of the PMF without overtopping and significant erosion.
