Abstract:

The Dam is an earthfill structure about 1000 feet long and 23.3 feet high with a gravel roadway traversing the entire dam. The dam is classified as small on the basis of size, and given a hazard classification of significant on the basis of downstream area development. The principal spillway consists of a 42-inch diameter corrugated metal pipe CMP vertical riser connected to a 36-inch diameter CMP which passes through the dam at a low level. The emergency spillway is an open earth channel cut in the left abutment. The spillways will pass 10 percent of the PMF or 20 percent of the SDF without overtopping the crest of the dam. The spillway is adjudged inadequate but not seriously inadequate. The visual inspection revealed that there are no immediate needs for remedial measures, except for the monitoring of the spring beneath the primary spillway outlet. It is recommended that a regular maintenance and operations program be instituted with provisions for accurate records of all maintenance performed.
