National Program for Inspection of Non-Federal Dams, South Silver Floodwater Retarding (MA 00702), Connecticut River Basin, Sandisfield, Massachusetts. Phase 1 Inspection Report
The dam is comprised of an earth embankment, a central principal spillway, and and emergency spillway. The embankment has a maximum fill height of approximately 31 feet and a crest length of 170 feet. The principal spillway consists of a concrete intake riser structure, an impact basin, and a 30 inch diameter reinforced concrete connector pipe. The visual inspection indicated the dam to be in generally good condition. The test flood (1/2 PMF) will produce an inflow of 1620 cfs. The resulting outflow through the spillway is 1120 cfs at elevation 1189, a surcharge of 5.5 feet. The spillway has a capacity of 1920 cfs at elevation 1191, top of the dam. The dam is in generally good condition. It is felt, however, that certain items need attention. These include extension of riprap protection along the dike forming the left training wall of the emergency spillway and refastening of two trash angles on the intake riser.
