Butterfield Pond Dam is a stone-filled gravity structure about 210 feet in overall length and 12.5 feet high from crest of dam to toe of slope, Located in the center of the dam is the principal overflow section which is 57 feet long and consists of a concrete capped, stone weir with concrete training walls, Near the middle of the overflow section is a 16.2 feet wide by 0.2 feet deep low flow spillway weir cast into the concrete cap. As a result of the poor visual inspection of this facility, the dam is considered to be in very poor condition. It is small in size with a significant hazard potential. The recommendations and remedial measure should be implemented as soon as possible. Keywords include: Inspection, Dam safety, Connecticut River Basin, Washington, New Hampshire, and Ashuelot River.
