Hyde Pond Dam Removal

Location: Connecticut

Project type: Resilience

Project status: Complete

Funding awarded: $551,250


Hyde Pond Dam removal completed February 2016.

In May 2016, volunteers planted native vegetation at the dam site along the banks of Whitford Brook, which is now flowing freely for the first time in 350 years.

Project Summary

The Hyde Pond Dam Removal project will remove the dam on Whitford Brook, a tributary of the Mystic River. It will restore fish passage to 4.1 stream miles and habitat for alewife, blueback herring and American eel, candidate species under the Endangered Species Act, and mitigate flooding risk downstream of the dam.

Conservation Goals

  • Restore fish passage to 4.1 stream miles providing alewife, blueback herring and American eel with access to historic habitat
  • Mitigate flooding risk downstream of the dam

Project Benefits

  • Reduces river flood flow elevations to enhance downstream flood control, since removal of the Hyde Pond Dam provides flood storage capacity for the watershed
  • Reduces the threat of flooding and property damage
  • Restoring connectivity also provides for natural sediment transport, which will contribute to coastal beach development and enhance natural defenses in the coastal environment.

Project Partners

  • Connecticut Fund for the Environment / Save the Sound
  • Connecticut Department of Energy and Environmental Protection (CT DEEP)
  • Private dam owner
  • National Oceanographic and Atmospheric Administration (NOAA)
  • The Avalonia Land Trust and the Isaac School (New London, Conn.
  • Town of Groton
  • Town of Stonington
  • Save-The-Sound

Additional Details

The project helps support the local tourism economies and related activities such as wildlife viewing, recreational angling and commercial fishing. In addition, Increasing fish access to spawning and nursery habitat will help build a sustainable fishery and reduction of flood risk help maintain road/bridge infrastructure as well as restore coastal wetland and beach processes.
