Centennial Dam ribbon cutting

DedhamToday, at a ribbon cutting ceremony, the Baker-Polito Administration celebrated the completion of $1.3 million in improvements made to the Centennial Dam in the Town of Dedham. The dam, which was originally constructed prior to the 1900’s to power a variety of mills along Mother Brook (a man-made water conveyance that moves water from the upper reaches of the Charles River into the Neponset River), currently serves as a critical component to the Department of Conservation and Recreation’s (DCR) flood control system protecting the metropolitan Boston area.

“The improvements and upgrades made to Centennial Dam serve as great examples of the Baker-Polito Administration’s continued efforts to safeguard the Commonwealth’s invaluable infrastructure,” said Department of Conservation and Recreation Commissioner Leo Roy. “This major investment will ensure the dam remains in proper working condition and will enable the DCR to better manage the region’s flood control system.”

Starting in November 2017, the DCR began the Centennial Dam improvements and upgrades project, which included:

  • Reducing the height of the left downstream masonry wall, regrading of the downstream left embankment, and constructing a planter buttress;
  • Constructing an auxiliary spillway to increase spillway capacity;
  • Installing a gravity block wall on the right downstream embankment and regrading the area to reduce the slope;
  • Removing trees and other woody vegetation;
  • Installing cured-in-place linings inside the twin 48-mid-level outlets;
  • Replacing the right discharge channel wall;
  • Replacing the low level outlet gate;
  • Installing a segmental block parapet wall along the dam crest to reduce the potential for overtopping; and,
  • Repairing the interface between the right training wall and dam.
