2025 Water Reporter Impact—by the Numbers
Every photo tells a story. And in 2025, volunteer Water Reporters across the Casco Bay watershed helped tell an important one.
Baykeeping is our mission put into practice: acting to improve and protect the environmental health of Casco Bay. Our Baykeeping program exists to advocate for solutions to environmental challenges facing the Bay. In short, Baykeeping is about reducing pollution and addressing climate change. This is our most visible program and it has generated significant permanent and positive changes for the Bay.
When Friends of Casco Bay formed in 1989, it was with the recognition that a dedicated community was needed to care for our coastal waters. Scientists and researchers had discovered Casco Bay held loads of heavy metals, pesticides, and bacteria, as well as legacy contaminants from historic industries. The Bay lay at a tipping point. Powerful legislation like the Clean Water Act was in place, but science and laws alone were not sufficient to protect the health of Casco Bay; the Bay needed a voice to speak on its behalf.
At Friends of Casco Bay, our Baykeeping is guided by a passion for clean water, common decency, the regulatory environment, and science. We “listen” to the Bay as we monitor water quality and collect data to identify threats to the health of our coastal waters. This dynamic combination of science and advocacy, as well as our “work with” approach, led to the historic clean-up of the Julie N oil spill, designation of Casco Bay as a federal No Discharge Area, closure of a toxic paper mill, and the reduction of pesticide and nitrogen pollution along the Bay’s coast. These are just a few of the victories won by our Baykeeping program for the health of Casco Bay.
“Being the Casco Baykeeper is a way of life. It’s fundamental to who I am and stems from a life-long, deep connection to water. As Baykeeper it’s my responsibility to improve and protect the health of Casco Bay, serve as its voice, and act as its chief advocate.” – Ivy Frignoca, Casco Baykeeper
The Casco Baykeeper leads our Baykeeping Program. Ivy describes her role as the “Lorax” of the Bay, acting as the eyes, ears, and voice of Casco Bay. As Casco Baykeeper, Ivy is one of hundreds of Waterkeepers around the world who have dedicated themselves to speaking for their local waters. Collectively they form the Waterkeeper Alliance, of which Friends of Casco Bay is a founding member.
