Removing the White Rock and Bradford Dams and Assessing the Potter Hill Dam Fishway on the Pawcatuck River and removing the Shady Lea Mill Dam on the Mattatuxet River
Location: Connecticut and Rhode Island
Project type: Resilience
These projects will restore connections of streams to regional river systems, enhance fish passage and reduce the risk of flooding and dam failure during future storm events. Two dams will be removed and one fishway will be repaired or replaced on the Pawcatuck River in Rhode Island and Connecticut. One dam will be removed from the Mattatuxet River in North Kingstown, Rhode Island where 0.5 mile of stream access will be restored and a new natural riparian area will be created in a former water impoundment. This will benefit river herring and American eel.
- Restore river connectivity and enhance fish passage at all four sites benefiting river herring, American shad and American eel
- Reduce the risk of dam failure and flooding during future storm events
- Reduces or eliminates flood risk from aging dams
- Restores river access to Trust species in 22 miles of mainstream habitat, 48 miles of tributaries and 1,967 acres of pond habitat for migratory fish populations in the Pawcatuck River, Mattatuxet River, Little Narragansett Bay and surrounding estuaries
- Significantly increases benefit to commercial and sport fishing

Hurricanes Sandy and Irene spotlighted a need for removing aging and obsolete dams in the Northeast to eliminate flood risk to adjacent communities. Removing these dams will address these human safety and liability concerns. Additionally, the project has the potential to increase fish populations, and according to the the 2011 USFWS National Survey of Fishing, Hunting, and Wildlife-Associated Recreation, over $130 billion is generated by fishing and fishing-related industries on these rivers and around the bay, and an increase in catch could provide significantly increased economic benefit to the region.
