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 is classified as a small size dam with a high downstream hazard potential. The inspection and evaluation indicates the spillway does meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. The criteria for a spillway on a small dam in the high hazard category is that the spillway pass 50 to 100 percent of the probable maximum flood without overtopping the dam. The spillway will not pass the probable maximum flood without but will pass 70 percent of the probable maximum flood. Considering the small volume of water impounded and the large flood plain downstream, one-half the probable maximum flood is the appropriate spillway design flood. Deficiencies visually observed by the inspection team were erosion, seepage at and undercutting of the concrete chute apron, and the presence of one small tree on the downstream embankment slope. There were no observed deficiencies or conditions existing at the time of the inspection which indicated an immediate safety hazard.
