Abstract : The Tihonet Pond No. 2 Dam consists of an earth embankment with a vertical stone masonry wall over a portion of the downstream face. The embankment has a minimum top width of approximately 30 feet, a maximum height of 15 feet, and upstream and downstream slopes that vary from vertical at a downstream cut-stone masonry wall to approximately 2 H to 1 V. The overall length of the dam is approximately 660 ft. Included in this length are two spillway structures located at the left and right ends of the dam. These structures consist of stoplogs in concrete slots emptying into conduits that pass through the dam. Based on visual inspection and a review of all available pertinent data, the dam is considered to be in poor condition. Features that could effect the structural integrity of the dam include wet areas at the downstream toe of the dam, erosion and slumping of dam slopes, extensive tree growth on the dam slopes, movement of the downstream vertical masonry wall. The test flood would overtop this dam by about 0.5 ft., it would also overtop a second dam located on this pond, Tihonet Pond No. 1 Dam, by about 2.5 ft. The crest of this second dam is approximately elevation 40 NGVD. The spillway for this dam would carry about 10% of the Test Flood.
