Abstract:

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 an intermediate size dam with a high downstream hazard potential. The inspection and evaluation indicates 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 30 percent of the probable maximum flood without overtopping. Deficiencies visually observed by the inspection team were erosion, seepage, and presence of excessive brush and small trees on the downstream embankment slope. Also, the sloughing of the riprap on the upstream embankment slope has contributed to erosion of the embankment material. Seepage and stability analyses are not available as required for dams having the above size and hazard potential as required by the guidelines. There were no observed deficiencies or conditions existing at the time of the inspection which indicated an immediate safety hazard.
