摘要

Saw Creek Club Dam is an earthfill and rockfill embankment. It is 500 feet long and its design height is 16 feet at maximum section. At present, the dam is 14 feet high. The concrete gravity spillway is located at the left abutment of the dam. The spillway is 154 feet long; the leftmost part of the axis of the weir deflects downstream. According to criteria established for these studies, the spillway capacity of Saw Creek Club Dam is rated as seriously inadequate and the dam is classified as unsafe, non-emergency. The existing spillway will pass only 9 percent of the Probable Maximum Flood (PMF) without overtopping of the dam. No stability problems were evident for the embankment at the time of the visual inspection, but a potential hazard exists due to significant seepage at the toe of the dam. The spillway weir is judged to be stable for the expected loading conditions.
