Mathers Pond Dam is concrete gravity and an earth embankment approximately 280 feet long and 18 feet high. The principal spillway is located approximately at the center of the dam and is 5 feet long and 1 foot deep. However, the entire concrete portion is considered an emergency spillway. A 12-inch low level discharge pipe passes through the base of the dam and is located below the spillway. The control for this discharge pipe is on the upstream face. The drainage ara is 0.5 square miles and the pond has 100 acre-feet of available storage. The assessment of the dam is based on the visual inspection, available drawings, past operational performance and hydraulichydrologic computations. The dam is judged to be in fair condition with several areas that require attention. These areas include seepage through the dam and at the toe of the dam, vegetation on the embankments and along the toe of the dam an the non-operating status of the discharge pipe.
