Flock Process Dam Removal

Location: Connecticut

Project type: Resilience

Funding awarded: $970,000

Project Summary

The Flock Process Dam Removal project removes the first dam on the Norwalk River, eliminating dam failure risk, allowing fish to move freely between salt and freshwater, facilitating sediment transport and building natural defenses in both upstream and downstream areas of the river to future flooding. Approximately 3.5 miles of stream access are being restored.

Conservation Goals

  • Remove the Flock Process Dam

Project Benefits

  • Restores 3.5 miles of stream access benefiting migratory fish including alewife, American eel, alewife, sea-run brown trout and blueback herring
  • Eliminates dam failure risk while protecting upstream and downstream infrastructure
  • Restores natural sediment transport

Project Partners

  • Connecticut Department of Energy and Environmental Protection - Inland Fisheries Division
  • City of Norwalk
  • Norwalk River Watershed Initiative

Additional Details

The 14-foot high dam served an adjacent former mill but now the dam is abandoned and in a state of disrepair. Failure of this dam threatens downstream property and habitat, two downstream bridges (including an active Amtrak bridge) and an upstream office complex.
