National Program for Inspection of Non-Federal Dams. Springfield Water Works Intake (MA 00708) Connecticut River Basin, Russell, Massachusetts. Phase 1 Inspection Report

摘要

The Springfield Water Works Intake dam is an approximate 295 foot long concrete masonry structure spanning a gorge in the Little River. This dam is built on a 180 foot radius and appears to be functioning as an arch. The visual inspection of this dam did not disclose any findings that indicate an unsafe condition. The spillway for this dam is able to pass a 1/2 PMF flow from its own drainage area of 3.15 s.m. It must be noted however, that the Cobble Mountain Reservoir, some 2.75 miles upstream, could affect the flow at this site. Should the Cobble Mountain Reservoir be full and overflowing its spillway at a time of flooding conditions, the flow at this site would change significantly. It is recommended that the owner have repairs made to certain spalled areas of the intake structure and wasteway.
