Geographic Scope

The SuAsCo CISMA (Cooperative Invasive Species Management Area) is a partnership of organizations that intend to manage and control invasive species defined by the geography of the Sudbury, Assabet, and Concord (SuAsCo) watershed. Thirty-six towns are part of the SuAsCo Watershed, and we are all connected by the Sudbury, Assabet, and Concord river system. The watershed covers approximately 377 square miles and includes a variety of upland habitats, wetland habitats, historic sites, scenic sites and recreational areas. The towns, state and federal government agencies, and environmental organizations that hold land in the watershed all share an interest in the work of the CISMA.

 

 

RiverFest 2018 

Join us at RiverFest , June 16th and 17th—a weekend of free activities, from Lowell to Framingham, celebrating our local Wild and Scenic Rivers. With free walks, music, and family-friendly adventures, there is something for everyone. For events and information, visit www.sudbury-assabet-concord.org.  

In recognition of their remarkable value, Congress designated the Sudbury, Assabet and Concord Rivers as part of the national Wild and Scenic River System in 1999. The River Stewardship Council was created to promote preservation of these resources. The Council is a partnership of representatives from eight communities, state and federal agencies, and three local organizations.

To be expected, the boundaries of the SuAsCo watershed do not match up with the boundaries of the towns within the watershed. Listed below are the towns that are fully or partially within the watershed. The towns whose land is less than fifty percent within the watershed are noted by their gray text coloration.
