National Program for Inspection of Non-Federal Dams. Granville Reservoir Dam MA 00707, Connecticut River Basin, Granville, Massachusetts. Phase I Inspection Report.
Abstract
Granville Reservior Dam is an earth dam approximately 850 feet long with a maximum hydraulic height of about 106 feet. A concrete spillway, with a 1-foot high flashboard and concrete discharge channel, is located at the south abutment. The spillway has a weir length of approximately 60 feet. The concrete end walls for the spillway support a steel truss bridge above. A 42-inch concrete pipe conduit through the dam serves as a low level emergency outlet for the reservior. A 24-inch water supply main draws water from a reservior for distribution to the City of Westfield. Based on engineering judgement and the past performance of the dam and outlet works, the project is considered to be in fair condition at the present time. The project, however, does have a number of deficiencies which, if not remedied, have the potential for developing into serious conditions. The capacity of the spillway with water at the low end of the top of dam is 6700 cfs which is about 80 percent of the test flood discharge, The discharge capacity of the 42-inch gate, alone, with water at the top of the dam is 280 cfs (or 3% of the test flood discharge).
