Mirror Lake Dam is a concrete gravity dam housing two stoplog spillway bays with earth embankments extending to the east and west of the concrete structure. It is 290 ft. long with a hydraulic height of 11.5 ft. The dam is in poor condition. Trees and brush growing on the embankments, and a lack of erosion protection on the upstream slopes and crests of both embankments are of major concern. It is small in size with a significant hazard potential. Keywords include Visual inspection, Dam safety, Merrimack River Basin, Woodstock New Hampshire, and Tributary to Hubbard Brook.
