Our Waters Define Southwest Florida
From the Caloosahatchee River to our coastal estuaries, clean water connects us—to nature, to each other, and to the future of this place we love. While our waters face real challenges, progress is possible when people step up. Calusa Waterkeeper works every day to protect these ecosystems through science, advocacy, and community action. When you become a member, you’re part of a growing movement dedicated to clean water and a healthier Southwest Florida for generations to come.
Your membership empowers local protection efforts, science‑based solutions, and a strong, independent voice for our waters.
