National Dam Safety Program. Cedar Knoll Farm Lake Dam (MO 10782), Upper Mississippi - Salt - Quincy Basin, Warren County, Missouri. Phase I Inspection Report
The purpose of this inspection was to assess the general condition of the dam with respect to safety and, based upon this inspection and available data, determine if the dam poses a hazard to human life or property. According to the criteria set forth in the recommended guidelines, the magnitude of the spillway design flood for the Cedar Knoll Farm Lake Dam, which is classified as small in size and of high hazard potential, is specified to be a minimum of one-half the Probable Maximum Flood (PMF). Results of a hydrologic/hydraulic analysis indicated that the spillways (principal plus emergency) are inadequate to pass lake outflow resulting from a storm of one-half PMF magnitude or the outflow from the one percent (100-year frequency) flood without overtopping the dam. The spillways are capable, however, of passing lake outflow resulting from the ten percent chance (10-year frequency) flood and the outflow corresponding to about 12 percent of the PMF without over-topping the dam. According to the St. Louis District, Corps of Engineers, the length of the downstream damage zone, should failure of the dam occur, is estimated to be five miles. Accordingly, within the possible damage zone are four dwellings, several farm buildings and State Highway F.
