National Program for Inspection of Non-Federal Dams. Belleview Lake Dam (CT 00642), Naugatuck River Basin, Waterbury, Connecticut. Phase I Inspection Report.
Abstract
Belleview Lake Dam is a 229 foot long rubble masonry gravity dam and has a maximum height of 34 feet, with the spillway located on the right side of the embankment. The visual inspection of Belleview Lake Dam indicated that the dam is in poor condition. There are numerous instances where mortar has been removed from joints. The inspection revealed that extensive seepage occurs across the entire downstream face of the dam. Erosion was observed on the left abutment and seepage was also seen above elevation of the dam crest. Also, at the junction of the left abutment and the downstream face of the dam a 10 foot erosion channel is located which is filled with boulders, trees and rubbish. A similar erosion channel is located on the right side of the dam where seepage water flows down the slope. Numerous trees up to one foot in diameter are found on both abutments and along the toe of the dam. The spillway channel contains debris and trees and erosion has occurred to downstream channel walls. There is no apparent operable outlet to the reservoir. The spillway will discharge 95 cfs or 7% of the test flood with the pool level with the top of the dam. The test flood flow of 1430 cfs will overtop the dam by 1.5 feet. Also, the masonry construction of the dam would probably do some overtopping without significant damage.
