摘要

Green Hill Pond Dam is an earthfill embankment 200 feet long and 20 feet high with a stone masonry core wall 17 feet high. Generally the dam is in good condition although the outlets to the spillway and overflow diversion are in poor condition. Green Hill has been classified in the 'high' hazard category. There is potential hazard at the site. An inflow test flood of 280 cfs will overtop the main dam by an average of 0.2 feet. (Author)
