The Pawcatuck River Watershed

Study area of the Pawcatuck Watershed including Anguilla Brook.

The Pawcatuck River is 31 miles long and its watershed drains an area of 69,829 acres.  The watershed is mostly in Rhode Island with smaller areas located in Connecticut. The river flows from the outlet of Worden’s Pond (South Kingstown, Rhode Island) to Little Narragansett Bay in Westerly, Rhode Island and Stonington, CT.  The majority of the population within the watershed primarily consists of small towns and rural communities, except for the Towns of Westerly and Stonington. These two larger communities are found in the furthest downstream area of the watershed.

Key Water Quality Issue in the Watershed

Similar to many rivers in New England today, there are significant water quality issues that cause stress to the natural resources in the Pawcatuck River Watershed. One of the most significant is nutrient pollution impacting the estuary.  

Work on this project in the freshwater Pawcatuck River and watershed is supported by the Southeast New England Program (SNEP) Watershed Grants. SNEP grants are funded by the U.S. EPA through a collaboration with Restore America’s Estuaries (RAE). For additional information, go to the SNEP grant program
In a separate complimentary project, US EPA Chelmsford Lab, Rhode Island Department of Environmental Management (RIDEM), and Save The Bay will collect data for evaluation of water quality in the estuarine Pawcatuck and Little Narragansett Bay during 2019.

Thank you to the staff and members of the SNEP program for helping to make the Pawcatuck Nutrient Project a reality!
