National Dam Safety Program. Ray County Dam Number A-27 (MO 10233), Missouri - Kansas City Basin, Ray County, Missouri. Phase I Inspection Report.
Abstract
Ray County Dam No. A-27 was inspected 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. Our 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 not pass either the probable maximum flood or 50 percent of the probable maximum flood without overtopping but will pass 30 percent of the probable maximum flood and the 100-year flood. Considering the small volume of water impounded and the downstream hazard, 50 percent of the probable maximum flood is the appropriate design flood. Deficiencies visually observed by the inspection team were lack of riprap slope protection, erosion, seepage, and animal burrows in the embankment. There were no observed deficiencies or conditions existing at the time of the inspection which indicate 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.
