National Program for Inspection of Non-Federal Dams. Stevens Paper Company (Lower) Dam (MA 00074), Connecticut River Basin, Westfield, Massachusetts. Phase I Inspection Report.
Abstract
This dam generally consists of a 190 foot masonry spillway, an earthfill embankment and 2 outlet pipes. The dam was designed in 1955 by Stone and Webster Engineering Corporation to replace an earlier dam, which was damaged by the flood of that year. Construction which utilized portions of the original structure was completed in 1957. The visual inspection showed the dam to be in good condition. However, water passing over the spillway limited the inspection of the spillway. The spillway is capable of passing 96% of the test flood outflow. The top of the embankment, elevation 175, would be overtopped by about 1 foot. However, failure under this condition would only cause insignificant damage as the downstream flooding would have already occurred. The dam is generally in good condition. However, it is recommended that the owner repair the drawdown outlet, and operate it at least once yearly to insure continued adequacy. After this outlet is repaired, or during a period of low flow, the owner should engage a qualified engineer to inspect the spillway without water flowing over it. Also the erosion of a retaining wall downstream of the spillway on the right abutment side should be repaired.
