Book Description
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.

Book Description
The dam is a gravity structure of split stone masonry. It is about 160 ft. long and 15.6 ft. high. The drainage area for this dam covers 113 square miles of rolling woodland with some minor development and pasture. It is small in size with a significant hazard potential, since appreciable economic loss and possible loss of a few lives could result in the event of a dam failure. Since the risk downstream in the event of a dam failure is on the high side of significant, the 1/2 PMF has been adopted as the appropriate test flood. (Author).
