Climate Change

Across the world seas are rising, waters are warming, and oceans are acidifying. More intense storms batter our coasts with higher storm surges. Marine life faces shifting habitat ranges and increasing prevalence of disease. Casco Bay is no exception. As part of the Gulf of Maine, water temperatures in Casco Bay are rising faster than 99% of the world’s oceans. Because Casco Bay is changing and changing quickly, our Baykeeping must be adaptive and nimble. Responding to the impacts of climate change is our greatest challenge.

Stormwater Pollution

Stormwater runoff is a major source of pollution to Casco Bay. The Bay’s watershed begins over 60 miles away in Bethel, draining land that passes through many of Maine’s most densely populated areas. The rivers and streams that ultimately flow into Casco Bay collect runoff that contains a toxic mixture of car exhaust from our streets, fertilizers and pesticides from our lawns, and even raw sewage from our wastewater systems. As climate change brings more intense storms to Maine, these stormwater pollutant loads will likely increase.

Nitrogen Pollution 

Nitrogen is an essential nutrient found in all life forms and ecosystems. A healthy amount of nitrogen encourages algal growth in Casco Bay and supports the base of the food chain. Too much nitrogen from industrial agriculture, municipal wastewater, car exhaust, and lawn fertilizers causes excessive algal growth that harms the health of the Bay. As our waters warm and intense storms flush higher quantities of nitrogen into coves, we are seeing more nuisance algal blooms and their harmful impacts on the Bay.

Casco Baykeeper

“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. 

Waterkeeper Alliance is a global movement uniting more than 300 Waterkeeper groups around the world, focusing citizen action on issues that affect our waterways, from pollution to climate change. The Waterkeeper movement patrols and protects over 2.75 million square miles of rivers, lakes, and coastlines in the Americas, Europe, Australia, Asia, and Africa. For more information, please visit waterkeeper.org. 

You might see the Casco Baykeeper out on the Bay in our Baykeeper boat, the Research Vessel Joseph E. Payne, monitoring water quality and investigating citizen concerns. When not on the water, Ivy is often working with individuals, community leaders, business owners, and decision makers to keep the health of the Bay front-and-center, at all times. The Casco Baykeeper is a full-time advocate, working to ensure compliance with environmental laws, educating the public, and informing policy development.

Ivy has a life-long connection to Maine’s coast and has lived in the Casco Bay region for over 30 years. Ivy combines her passion for our coastal waters with decades of experience in environmental and marine advocacy. Before joining Friends of Casco Bay, Ivy was an attorney with the Conservation Law Foundation where she worked on marine issues affecting Maine and New England. At every step of Ivy’s career – and her life – clean water has been at the center.
