The dam is a 15 foot high stone masonry, gravity structure, probably founded on bedrock for its entire length. The project is approximately 193 feet in length, consisting of an 81 foot long masonry spillway section, a 32 foot long masonry and earthfill section to the left of the spillway, and an 80 foot long stone masonry and earthfill dike extending upstream from the spillway along the right side of the impoundment. Two wood sluice gates controlling flow to a downstream factory, are located at the left end of the dam. The spillway, with an overflow length of 77 feet, is a broad-crested masonry weir of trapezoidal cross-section, with a permanently attached timber crest and breakaway flashboards. Based upon visual inspection, the project is in poor condition. The following features could influence the future condition andor stability of the project 1 Areas of the upstream and downstream masonry faces of the dam and sluice gate channel are deteriorated. This deterioration includes missing or cracked mortar, and weathered or displaced stone blocks. 2 There is a seep of approximately 4 to 6 gallons per minute near the left end of the dam. 3 The low-level outlet is inoperable. 4 The upstream slope of the dike is eroded.
