Abstract:

This dam has been classified by the St. Louis District Corps of Engineers as an intermediate size dam with a high downstream hazard potential. Their estimate of the potential damage zone extends 6 miles downstream of the dam. The inspection and evaluation indicates that the spillway does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The spillway will pass 15 percent of the Probable Maximum Flood PMF without overtopping. The spillway will not pass the 100-year frequency flood without overtopping 15 percent of the PMF is smaller than the 100-year flood. The embankment and appurtenances inspected appear to be in good condition. However, the unlined spillway presents a potentially dangerous situation that should be corrected.
