National Dam Safety Program. Komer Lake Dam (MO 10995), Missouri - Nemaha - Nodaway Basin, Buchanan County, Missouri. Phase I Inspection Report.

Komer Lake Dam was inspected by an interdisciplinary term of engineers. The purpose of the inspection was to make an assessment of the general conditions 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. In accordance with the guidelines and based on visual observation, the dam is classified as having a high potential for damage and loss of life. Failure would threaten life and property. The estimated damage zone extends approximately two (2) miles downstream of the dam. Within the damage zone are three or four houses, two commercial buildings, and Highway FF, all of which are located in Agency. Our inspection and evaluation indicates that the spillways do not meet the criteria set forth in the recommended guidelines for an intermediate dam having a high hazard potential. The Probable Maximum Flood is the appropriate spillway design flood. The spillways will pass the 100-year flood (1% probability flood - having a one percent chance of being exceeded in any year) without overtopping the dam. The spillways will pass 21% 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.
