This project developed the foundation for an Exeter-Squamscott Watershed Integrated Plan for the communities of Exeter, Stratham, and Newfields in southern New Hampshire. The Plan helped communities meet new wastewater and stormwater permit requirements and improve water quality in the Squamscott River and the Great Bay, while supporting the economic viability of participating communities. This project developed a management plan for three communities that allows them to evaluate and manage water quality and climate impacts at the scale of the Exeter-Squamscott subwatershed project area.
