National Dam Safety Program. Branneky Lake Dam (MO 31393), Missouri - Kansas City River Basin, St. Louis County, Missouri. Phase I Inspection Report
Branneky Lake Dam was inspected. The inspection and evaluation of the consultant's inspection team indicate that the spillway of Branneky Lake Dam does not meet the criteria set forth in the guidelines for a dam having the above size and hazard potential. Branneky Lake Dam being a small size dam with a high hazard potential is required by the guidelines to pass from one-half of the Probable Maximum Flood to the Probable Maximum Flood without overtopping the dam. Considering the small drainage area, the small storage capacity of the reservoir, the height of the dam, and the small number of dwellings in the downstream hazard zone, one-half of the Probable Maximum Flood is considered the appropriate spillway design flood for Branneky Lake Dam. The Probable Maximum Flood is defined as the flood discharge that may be expected from the most severe combination of critical meteorological and hydrologic conditions that are reasonably possible in the region. It was determined that the reservoir can store approximately 5 percent of the Probable Maximum Flood without overtopping the dam. The evaluation also indicates that the reservoir cannot accommodate the ten-percent chance flood without overtopping the dam.
