Missouri Missouri Kansas City Basin Elliot Davis Lake Dam Howard County Missouri Phase 1 Inspection Report National Dam Safety Program PDF Download

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. The inspection and evaluation, indicates that in consideration of the small volume of water impounded, the large floodplain downstream and the two houses downstream, 50% of the Probable Maximum Flood is the appropriate design flood. The spillway of this dam meets this criteria. The spillway will pass the 100-year event as well as 75% of the Probable Maximum Flood (PMF) 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. Seepage and stability analyses comparable to the requirements of the 'Recommended Guidelines for Safety Inspection of Dams' were not available, which is considered a deficiency. These analyses should be obtained in the future.
