The Heartbeat of Long Island, The Great South Bay

For so many of us, the Great South Bay is more than just a body of water. It’s where we fish with our families, where kids learn to love the water, and where the tides tell the story of who we are. The Bay is not just an asset—it’s our way of life. Let’s protect it, together.

This Earth Day: Join Us in Protecting the Great South Bay!

At Save The Great South Bay, we’re a passionate community of Long Islanders committed to restoring and preserving the bay that has shaped our lives for generations, clamming, oysters, fishing, sailing, and more. We’ve experienced the devastating effects of brown tide, such as beach closures, no-fishing zones, and massive fish kills. As a local environmental nonprofit, we work to improve and protect water quality in the Great South Bay.
