Langers Pond Dam is a 10.5 foot high, L-shaped, run-of-the-river stone masonry gravity structure. The dam was constructed in 1880 to supply water for the generation of power for the mill at the dam, now the Simonds Company. In recent times, the power generating facilities have been inoperable, however, the present owner is in the process of restoring these facilities. The drainage area is approximately 97 square miles and the maximum impoundment to the top of the dam is 156 acre-feet. Because the dam is a run-of-the-river structure, the entire length of the dam is used as a spillway. It is 160 feet in length, and constructed of stone masonry with a concrete section along the upstream face. Based upon the visual inspection, the project appears to be in good condition. The following features which could influence the future condition andor stability were identified. 1 Stones appear to have become dislodged from the downstream face at the left side of the dam 2 The downstream end of the left training wall needs repair. The wall in this area is broken up and falling into the channel. 3 There is no low-level outlet at the dam. However, if the exisxting sluiceway and gates are repaired, this should provide a sufficient outlet.
