Abstract:

The Bristol Reservoir Dam is an earthfill embankment with a stone masonry core that is 250 feet long and 25 feet high. It has a 200 foot long, 12 foot wide stone masonry spillway channel and a 10 inch cast iron diversion conduit. The dam is classified as small in size and has a high hazard potential based on downstream habitation. Based n the visual inspection data and past operational performance, the dam is judged to be in fair condition. There are areas which should be studied in order to monitor the dams behavior such as the excessive seepage at the base of the spillway channel and the seepage through the body of the dam. The drainage area contributing to the dam is 0.359 square miles. The routed test flood outflow one-half Probable Maximum Flood is 404 cfs and would overtop the dam by 1.15 feet. The project will pass only 50 percent of the routed test flood peak outflow before overtopping the dam.
