South Shore watershed associations, towns and their state and federal partners have been leaders in Massachusetts in improving stream connectivity through dam removals and cranberry bog restoration projects resulting in…

• 21 dam removals and 2 bog restoration projects since 2002
• Opening 12 miles of streams and rivers
• Providing an additional 15 miles of partial access through fish passage structures

We have made progress, but there is still more to do. Overall, 6% of available habitat has been re-opened and 74% of restorable habitat is still blocked by dams.

Dam removal not only improves access for migratory fish like river herring and Eastern brook trout, it also improves water quality, helps maintain streamflow, and improves instream habitat. When river herring can access more habitat, their population increases, providing more food for the animals that eat them like striped bass, bluefish, osprey, and herons.
