National Dam Safety Program. Structure Number 1 - Williams Creek Dam (MO 10728), Missouri - Kansas City Basin, Clay County, Missouri. Phase I Inspection Report.
Abstract
Structure No. 1 - Williams Creek was inspected by an interdisciplinary team of engineers. 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. Our inspection and evaluation indicates that 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 the 100-year frequency storm and also the storm equal to 29% of the Probable Maximum Flood without overtopping the dam. The Probable Maximum Flood (PMF) is defined as the flood that may be expected from the most severe combination of critical meteorologic and hydrologic conditions that are reasonably possible in the region. Additional deficiencies, in accordance with the guidelines, are the lack of seepage and stability analysis. These analyses should be obtained in the future. Other deficiencies visually observed by the inspection team were a few small trees growing on the upstream embankment slope, some erosion of the downstream berm and low spots in the crest of the dam were water ponds.
