Watershed Stewardship

The twenty streams that wind through Lexington play important roles in our community, moving and cleaning water, providing wildlife habitat, creating wetlands, and serving as aesthetically pleasing places to visit.

All of Lexington's streams start within the bounds of Lexington and flow outward to other communities in three major watersheds — the Charles River Watershed, the Shawsheen River Watershed, and the Mystic River Watershed. As they flow through these urban areas, the streams face challenges from stormwater run-off and other factors.

Lexington's Engineering Division, in partnership with an internship program through the UMASS Lowell Francis College of Engineering, monitor and tend to the health of our streams. The original Watershed Stewardship Program, started in 2012, engaged Conservation Steward volunteers to conduct observational stream surveys on all of Lexington's streams to develop a better understanding of the issues that affect their health and function. Follow-up efforts to these surveys include outreach and education projects, stream clean-ups, and water quality monitoring.

Storm Drain Marker Installation Project

Lexington's Watershed Stewards installed storm drain markers in Lexington Center in order to educate residents and visitors about the connection between streams and storm drains. Look for the round, green markers that say "Don't Dump, Drains to Stream" throughout Lexington Center. Future installations will focus on other neighborhoods and areas throughout town.
