National Program for Inspection of Non-Federal Dams. Addison Pond Dam (CT 00245), Connecticut River Basin, Glastonbury, Connecticut. Phase I Inspection Report.
Abstract
Addison Pond Dam is a stone masonry structure, 88 ft. long with short, low earth embankments extending 70 ft. east and 30 ft. west. The masonry dam has a top width of 2 ft. and a maximum height of approximately 18 ft. There is a 31/2 ft. x 4 ft. regulating outlet through the west side of the spillway. The operating mechanism for the outlet is currently inoperable. Based on visual inspection, the Addison Pond Dam is judged to be in poor condition. Several areas require repair work and/or monitoring. Some features found existing that could affect the stability of the dam are considerable leakage through the spillway and the eastern portion of the dam structure, state of general disrepair of the entire project and continuous flow of water from the foundation of the warehouse. The spillway capacity is 600 cfs with the water level at the top of the dam. The spillway is capable of passing only 13% of the test flood flow without overtopping the dam. The storage capacity up to the top of the dam is 62 ac. ft. and up to the test flood level is 115 ac. ft.
