National Program for Inspection of Non-Federal Dams. Vistron Dam (MA 00759), Connecticut River Basin, Northampton, Massachusetts. Phase 1 Inspection Report
Vistron Dam, also known as Pro Brush Dam is a stone masonry gravity dam across the NMill River. The dam has a hydraulic height of 24 feet, 195 feet long, 8 feet wide at the crest with downstream face battered at approximately 1H: 12V. The spillway section of the dam is 140 feet long. The dam is founded on bedrock which is exposed at the southwesterly abutment and along the base of the dam. The dam is presently in good condition with no major problems. The main deficiency noted is the presence of trees growing near the top and out of the side of the dry laid stone retaining wall at the northeasterly abutment. Considering a 20,000 cfs inflow, from the 52 square mile drainage area, and assuming no downstream controls, the dam would be overtopped by approximately 4 feet. Spillway capacity at the top dam is 10,500 cfs which is approximately 4 feet. Spillway capacity at the top of dam is 10,500 cfs which is approximately 52 percent of the 1/2 PMF.
