National Program for Inspection of Non-Federal Dams. Glenville Pond Dam (CT 00334), Shetucket River Basin, Stafford, Connecticut. Phase I Inspection Report.
Abstract
Glenville Pond Dam is an earth embankment dam with downstream stone walls and a reinforced buttress type spillway. It is approximately 240 feet long, 15 feet wide at the crest and 19 feet high at the lowest point of the river. The concrete buttress spillway is 100 feet long and 17 feet high; there are 5 buttresses at 25 feet on center. an inlet for a power canal is located on the right side of the dam. It is a 5 foot diameter steel pipe imbedded in concrete from which the gate mechanism has been removed. Presently, the power canal returns the flow into the river, since the downstream mill has been demolished. The dam is located on Furnance Brook and has a watershed area of 15.8 square miles. There are a number of reservoirs upstream of this facility, each of the which has significant impact on the flow at Glenville Pond Dam. The storage capacity of Glenville Pond is 110 acre feet at the top of the dam. As a result of the visual inspection and hydrologic and hydraulic computations, the dam is considered to be in POOR condition. To assure the long-term performance of this structure, several items will require further attention. These items concern themselves with the deteriorated condition of the spillway, its training walls and its apron. There are also problems with the masonry wall at the power canal intake, the walls on the downstream side of the dam, the lack of a gate at the power canal intake, and tree growth on the dam. The maximum outflow capacity of the spillway and headrace with water level at the top of the dam is 1,200 cfs, which represents approximately 12% of the test flood.
