Abstract:

The dam is a homogeneous earthfill structure about 1425 ft long and 48 ft high. The principal spillway consists of a 400 ft long reinforced concrete overflow weir. The weir overflows onto a 20 ft wide concrete apron 1.5-2.0 ft below the weir crest. The concrete apron is also used as a roadway for access the dam. The dam is an intermediate size structure and is assigned a significant hazard classification. The spillway will pass 100 percent of the Probable Maximum Flood PMF without overtopping. The spillway is rated adequate. The visual inspection did not reveal any problems which would require immediate attention. The dam is considered stable but an emergency operation and warning plan should be developed. Furthermore, a staff gage should be installed to monitor water levels.
