National Program for Inspection of Non-Federal Dams. Messerschmidt Pond Dam (CT 00392), Connecticut River Basin, Westbrook, Connecticut. Phase I Inspection Report
The dam built in 1890, has a total length of 610 feet and consists of an earthfill dam, a principal spillway and two auxiliary spillways. The dam has 545 feet of embankment which is arranged in a horseshoe configuration, and impounds 910 acre-feet of water with the pond level to the top of the low section of the left embankment. The central and right embankments are 26 feet above the streambed of Falls River and the left embankment is 24 feet above the streambed. The principal spillway is a 63 foot masonry weir located between the central and left sections of embankment. A masonry corewall extends from the right spillway training wall into the central embankment. The dam is approximately 15 feet wide at the crest. The outlet facilities are a 10 foot by 5 foot concrete sluice to a turbine and tailrace in a powerhouse and factory located adjacent to the principal spillway. Based upon the visual inspection and past performance, the project is judged to be in poor condition. No evidence of instability in the embankments was observed. There are areas requiring attention such as trees and brush on the embankments, seepage through the central embankment, brush in the two auxiliary spillways, and erosion of the principle spillway. The total spillway capacity with the water level to a low section of embankment just to the left of the principal spillway is 770 cfs, which is equivalent to 12% of routed test flood outflow.
