National Program for Inspection of Non-Federal Dams. Kendall Company Number 1 Dam (MA 00047), Connecticut River Basin, Colrain, Massachusetts. Phase I Inspection report.
Abstract
Kendall Company No. 1 Dam is a run of river facility that diverts water into a flume leading to the company's plant. Within the river channel there is a rock-filled, timber crib spillway structure 238 feet long. This overflow structure has a topwidth of 5 feet, and it has 2.9-foot high flashboards on its crest. The height of the dam, measured at the abutments of the spillway overflow section, is 24 feet. Based on visual inspection, the dam is judged to be in poor condition. The major concerns with respect to the integrity of the dam are deterioration of the wood crib abutment structure at the right end of the overflow section; trees growing in the wood crib abutment structure, on the upstream and downstream sides of the right abutment and on the dike; hazards resulting from the existing breach in the dike; lack of adequate erosion protection on the bank of the downstream channel near the left abutment; trees growing on the strip of ground between the dry stone masonry wall, on the left side of the downstream channel, and the right side of the concrete-lined flume on the left side of the valley; and lack of a low-level outlet for the dam. The spillway capacities are, respectively, about 22 percent and 38 percent of the routed test flood outflows. The depths of overtopping of the dam and dike that would occur during the test flood are 4.2 feet with the flashboards in place, and 3.5 feet with the flashboards removed.
