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