National Program for Inspection of Non-Federal Dams. Roberts Meadow Reservoir. Middle Dam (MA 00761), Connecticut River Basin, Northampton, Massachusetts. Phase I Inspection Report.

This dam is a 403 foot long, 42 foot high stone masonry structure. The visual inspection did not disclose any findings that indicated an immediate unsafe condition. The city is in the midst of a program of pressure grouting this dam to stop leaking which was extensive. At the time of the inspection, water was still leaking through the dam but at a much lesser rate than previously reported. The dams spillway will not pass either the PMF or 12 PMF without overtopping the dam, and the spillway is not considered adequate. There is an area of standing water existing below the right abutment of the dam. This area should be cleaned and a surface drainage system installed.
