Our Work
Science
We “listen” to Casco Bay by collecting water quality data, enabling us to identify threats to the health of the Bay. We track water quality year-round from our three Continuous Monitoring Stations, and collect seasonal water samples around the Bay.
Advocacy
Advocating for clean marine water is at the core of our work. Led by our chief advocate, the Casco Baykeeper, our staff and community lend the Bay our voices. We advocate for the health of our coastal waters in town halls and the state legislature, and work with businesses and environmental agencies to promote clean water policies and practices.
Get Involved
The name Friends of Casco Bay was chosen with purposeful intent. It takes a community to care for the Bay. We host events to educate the public on issues affecting the Bay and coordinate volunteer efforts to improve its health. We are proud to say that our volunteers and supporters are among the Bay’s most dedicated ambassadors.
