Smalltooth Sawfish is the “Canary in the Coal Mine”

The smalltooth sawfish is the center piece of Calusa Waterkeeper’s logo and represents our keystone species for the Caloosahatchee River & Estuary.


As your Waterkeeper, I wanted to take some time this month to explain in detail why the sawfish matters so much to our area. This critically endangered species now relies on Southwest Florida's mangrove-lined shallows as one of its last strongholds of critical nursery habitat remaining on the planet.


We've recently published an article describing how habitat loss, poor water quality and recent mass mortality events deeply threaten the species' recovery and what this signals about the health of our Caloosahatchee estuary. 


This is about more than protecting one species, this is a call for vigilance across the watershed. As guardians of the Caloosahatchee and Lee County's coastal waters, we must heed the sawfish’s warning: what has acutely threatened this species also impacts our ecosystem at large, and the health and economics of our communities.

🧫 Fecal Indicator Bacteria - May Results

CWK conducts Fecal Indicator Bacteria (FIB) water sampling at up to 32 sites in Southwest Florida each month. We publish the results to keep the public informed on potential risks. Enterococci bacteria found in water can cause gastrointestinal illness, infections, and rashes.


Results over 70 MPN would trigger an advisory from the Florida Department of Health if these sites were classified as "public bathing places." View the full results. (Please note conditions can change daily).

📣 Fixing SB 180 "Emergencies" Bill

Calusa Waterkeeper recently signed on to an effort led by 1000 Friends of Florida seeking to repeal/rewrite portions of SB180. Introduced by Sen. Nick DiCeglie (R) Pinellas and passed by the Florida Congress in 2025, this law contains broad, over-reaching language that is freezing local planning changes across the state.


"These provisions threaten the constitutionally guaranteed role of local governments to plan for growth to protect natural resources, water quality and public safety."
