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.

Explore the Issues

Waterways around the world are under attack by pollution and mismanagement. Southwest Florida is no different.

Calusa Waterkeeper is focused on several local action items as well as regional and national issues affecting our water policy and quality of lives.

We think you’ll agree, these are causes worth fighting for.

Taking Action

Calusa Waterkeeper is directly involved in two pieces of litigation seeking to compel federal and state agencies to take more responsibility in limiting harmful discharges and algal blooms to Florida’s coasts.

Lawsuit Launched Challenging Feds’ Failure to Fully Assess Harms of Lake Okeechobee Toxic Releases to Protected Sea Turtles, Sawfish

Conservation groups filed a notice today of their intent to sue the Trump administration for failing to acknowledge the harms that toxic releases from Lake Okeechobee pose to protected wildlife like sea turtles and smalltooth sawfish. The Center for Biological Diversity, Calusa Waterkeeper and Waterkeeper Alliance say the National Marine Fisheries Service and the U.S. Army Corps of Engineers failed to fully consider how the toxic algae and other pollutants from the Corps’ lake discharge harm wildlife, especially when they occur at the same time as red tide.

Florida Department of Environmental Protection Petitioned to Protect People From Harmful Algae Blooms

The Center for Biological Diversity, Sanibel-Captiva Conservation Foundation and Calusa Waterkeeper petitioned the Florida Department of Environmental Protection to protect the public from toxins in the harmful algal blooms that keep reoccurring in the state. This petition requires the department to consider adopting pollution limits for algae cyanotoxins, which are linked to liver disease and neurodegenerative risks in people. The state could be the first to establish water-quality criteria to protect swimmers, boaters and fishermen from recreational exposure to the dangerous cyanotoxins.
