Fighting for Drinkable, Fishable, Swimmable Water

Since 1995

Calusa Waterkeeper is a non-profit organization dedicated to the protection of the Caloosahatchee River & Estuary in Southwest Florida. This includes Lake Okeechobee & Estero Bay, plus the near-shore waterways of Lee County. We strive to achieve this mission through education and promotion of responsible use and enjoyment by all people.

Thank you for all that you’re doing to improve our water quality and to educate us on changes we ourselves can make to help.
