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 spillways do not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. Based on visual observations, this dam appears to be in satisfactory condition. Deficiencies visually observed by the inspection team were wave action erosion and erosion gullies on the upstream face and animal burrows on both faces of the embankment. The lake level was observed to be considerably below the rip rap elevation at the time of the inspection. Seepage and seismic stability analyses required by the guidelines were not available. There were no observed deficiencies or conditions existing at the time of the inspection which indicated an immediate safety hazard. Future corrective action and regular maintenance will be required to correct or control the described deficiencies. In addition, detailed seepage and stability analyses of the existing dam, as required by the guidelines, should be performed. A detailed report discussing each of these deficiencies is attached.
