National Program for Inspection of Non-Federal Dams. Milton Three Ponds Dam, (NH 00320), State Number 161.06, Piscataqua River Basin, Milton, New Hampshire. Phase I Inspection Report

摘要

The dam is 19 ft. high and 156 ft. long. It is a gravity dam consisting of a dry stone masonry bed over which a reinforced concrete superstructure has been built. The dam is in good condition. There are a few minor concerns which should be corrected. Based on size and hazard classifications in accordance with Corps guidelines the test flood is the PMF. A major breach at top of dam would probably result in the loss of less than a few lives and appreciable property damage. (Author)
