National Program for Inspection of Non-Federal Dams. Barre Reservoir Dam and Dike (MA 00094), Connecticut River Basin, Barre, Massachusetts. Phase I Inspection Report
The impoundment structures on Barre Reservoir consist of a 225-foot long earthfill dam and a 410-foot long earthfill dike. The spillway consists of a flat-crested, concrete weir 68.3 feet long and the low-level outlet is a 12-inch diameter iron pipe located at the dike, approximately 70 feet to the right of the left abutment. Generally, the dam and dike are in poor condition. The following deficiencies were observed at the site: severe seepage from the downstream toe of the dike at the left abutment; seepage along almost the entire length of both the dam and dike, at the downstream toe; heavy growth of vegetation on the crest and slopes of both the dam and dike; seepage through the vertical downstream stone spillway wall and beneath both left and right sidewalls of the spillway channel; minor bulging of the vertical stone spillway wall; spalling of the concrete approach apron, spillway crest, and splash apron, slight to heavy spalling of concrete along the upstream face of the spillway sidewalls; and an accumulation of debris in the spillway discharge channel. The test flood would overtop the dam by 0.1 feet but would not overtop the dike. Hydraulic analyses indicate that the spillway can discharge 1,370 cfs, or 93 percent of the test flood outflow before the dam is overtopped.
