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.
