Abstract:

The dam consists of a highway interchange U.S. Route 6 and Division Road with a vertical concrete wall on the left upstream face. The overall length of the dam is 360 feet, including a 125 foot long concrete overflow spillway located near the left of the dam. The outlet works located to the right of the spillway consist of 2 sluiceways controlled with stop logs. Located approximately 80 feet to the right of this sluiceway a second inoperable outlet consists of an intake structure and flume controlled with 2 slide gates. Based on visual inspection and a review of all available pertinent data, the dam is considered to be in fair condition. Features that could effect the structural integrity of the dam are cracks at the arch of the sluiceways, leaks at the downstream end of the flume, erosion of the upstream dam face, tree clusters on the upstream dam face, and deterioration of the masonry walls in the downstream channels. The Test Flood used overtops the dam by approximately 2.1 ft. The spillway carries approximately 50 of the Test Flood.
