Book excerpt: The purpose of the inspection was to make an assessment of the general condition of the dam with respect to safety, based upon available data and visual inspection, in order to determine if the dam poses hazards to human life or property. This dam has been classified by the St. Louis District Corps of Engineers as an intermediate size dam with a high downstream hazard potential. Should the dam fail, their estimate of the damage zone extends 5 miles downstream of the dam. The inspection and evaluation indicates that the combined spillways do not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The combined spillways will pass 39 percent of the Probable Maximum Flood without overtopping. The guidelines require that a dam of intermediate size with a high downstream hazard potential pass 100 percent of the PMF. The spillways will pass the 100-year flood. The embankment and appurtenances inspected appear to be in good condition. Minor deficiencies, including erosion, and brush and tree growth were noted and should be corrected by the owner.
