Abstract:

Based on a review of available design information and visual observations of conditions as they existed on the date of the field inspection, the general condition of the Breskin Dam No. 2 is considered to be good. The structure is classified as an intermediate size, high hazard dam and the Spillway Design Flood is the Probable Maximum Flood. The spillway capacity was found to be inadequate because the non-overtopping flood discharge capacity, as estimated using the HEC-1 computer program, was found to be 42 percent of the PMF. The spillway is not seriously inadequate, because in the opinion of the evaluating engineer, the dam will not fail at 50 percent of the PMF.
