Description of the Book:

The purpose of the inspection was to make an assessment of the general condition 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. This dam is classified as a small size dam with a high downstream hazard potential. Failure would threaten the life and property of approximately 3 families downstream of the dam and cause appreciable damage to highway FF, approximately 800 feet downstream of the dam. The spillway does not meet the criteria set forth in the guidelines for a dam having the above mentioned size classification and hazard potential. According to the guidelines, the spillway is required to pass the Probable Maximum Flood (PMF) without the dam embankment being overtopped. The spillway will only pass 38 percent of the PMF before the dam embankment is overtopped.

Because the spillway will not pass 1/2 of the PMF without overtopping, the dam is classified as ‘unsafe non-emergency.’ The spillway will pass the 100-year flood without overtopping, which is a flood that has a 1 percent chance of being exceeded in any given year
