National Dam Safety Program. Okaydy Reservoir Dam (MO 10001) Missouri - Kansas City Basin, Howard County Missouri. Phase I Inspection Report

The dam is an earth fill approximately 580 feet long and 23 feet in height. It is one of two dams on the University of Missouri Franklin Horticultural Farm. The spillway consists of a channel excavated through the left abutment. It is lined with concrete rubble masonry with three concrete transverse sills. It has a bottom width of about 50 feet. Our inspection and evaluation indicates that the spillway does not meet the criteria set forth in the recommended guidelines for a small dam having a high hazard potential. The spillway will pass 25% of the Probable Maximum Flood without overtopping the dam. Other deficiencies noted during the inspection are erosion of the upstream face at two locations, trees and shrubs growing along the waterline, seepage along the downstream toe from the left end to the right abutment trough, inlet sill of spillway blocked by beaver dam, small trees and brush growing on reservoir side of inlet sill, and downstream channel from spillway is overgrown with trees and brush.
