The Dam is an earthfill structure approximately 250 feet long and 26.1 feet high. The dam is classified as a small size dam with a significant hazard classification. The principal spillway is a concrete open channel located at the right abutment. The emergency spillway is a low area left of the dam used as an access road. The spillway is capable of passing 13 percent of the PMF without overtopping the crest of the dam. The spillway is adjudged as inadequate, but not seriously inadequate. The visual inspection revealed a seep on the downstream slope with evidence of piping. Also a shallow 12-foot wide depression was noted 40 feet right of the seep. It is recommended that a geotechnical engineering firm be retained within six months to evaluate the possible piping and the cause for the 12-foot wide depression. It is also recommended that within 12 months a regular maintenance program be initiated to maintain the integrity of the structure.
