Our mission is conserving and restoring migratory fish and resident aquatic species in the Connecticut River basin, and protecting the lakes, rivers, and wetlands where they live.

Although most U.S. Fish and Wildlife Service public lands and facilities have remained open for the public to enjoy, we ask that you Recreate Responsibly.

  • Check local conditions on this website and call ahead for current information.
  • Operations vary based on local public health conditions.
  • Consistent with CDC recommendations, people who are not fully vaccinated must continue to wear masks indoors and in crowded outdoor spaces.
  • Most importantly, stay home if you feel sick and continue to watch for symptoms of COVID-19 and follow CDC guidance on how to protect yourself and others.

About Us

We are working to restore migratory fish and resident aquatic species in the Connecticut River basin especially river herring (blueback herring and alewife), American shad, American eel, Atlantic sturgeon and shortnose sturgeon. We are also working with dam-owners on relicensing hyrdroelectric projects to minimize impacts to the environment and migratory fishes.

What We Do

The Connecticut River Fish and Wildlife Conservation Office works to restore and protect habitat for the migratory fish and resident aquatic species in the Connecticut River basin. We restore important habitat and fish connectivity between streams, rivers and lakes. Our projects improve water quality, help increase abundance of fish, and sustain the economic and recreational benefits derived from fishing and recreating in our public waters.

Projects and Research

Connecticut River Basin Fishway Passage Counts 

We are monitoring fish populations, cooperating on research studies, removing obstacles to migration, creating fishways so fish can migrate around dams, and boosting dwindling populations with fish from other stable populations.
