Abstract/Additional Information
On July 2, 2005, the dam on Hadlock Pond in the Town of fort Ann failed. The NY State DEC contracted with Clough, Harbour & Associates to conduct an engineering investigation on events leading up to the failure. The investigation report provides results of the physical examination of the site, including a topographic survey, test borings and trenches, and geophysical testing. It also analyzes design and construction documentation. Based on analysis of conditions at the dam site, construction records, and eyewitness accounts, Clough Harbour determined that internal erosion (piping) caused dam failure.
