πŸ‘€ On the Watch

Summer has arrived and the longer days, warming waters and frequent rainfall are typically a recipe for algal blooms and other water pollution events. As always, the Calusa Waterkeeper and our network of Rangers and connections are monitoring conditions closely. But we can always use your help! If you see an algal bloom or pollution in our watershed, please don't hesitate to report it to us.

Joe Cavanaugh Calusa Waterkeeper

As Amy Bennett Williams of the News-Press reported this month, cyanobacteria blooms have been observed at the Alva and Davis boat ramps along the Caloosahatchee. In the coming weeks and months we'll be stepping our "ADAM" airborne toxin research and could use the community's help in identifying potential sites.


Besides our dynamic weather patterns, there is always plenty going on in the world of water quality and local advocacy. In this month's newsletter you can read about a variety of issues: The City of Cape Coral has completed removal of the Chiquita Lock. The City Fort Myers plans to accept more wastewater from new development in Alva, while at the same time pleading with the Department of Environmental Protection for more time to improve their under-capacity and aging wastewater infrastructure. Residents in NW Cape Coral are pushing for a new outlet to Charlotte Harbor through an aquatic preserve. The state of Florida is building a detention center in the middle of the Everglades. The amount of pressures impacting our estuary and environment never stop; so neither will we.


There are number of ways you can help us work towards our mission of protecting and restoring our local waters: Report pollution, make a donation, volunteer for a committee, and join us at an upcoming event:

πŸ“ Chiquita Lock Removal

For anyone interested in the recently completed removal of the Chiquita Lock in Cape Coral, linked here is a position paper we published on the matter in 2020. Many poor decisions have transpired since then, but the facts about why the lock should have been upgraded instead of removed haven't changed. 


A summary from the document:


β€’ Long running narratives within the City lack a full understanding of the history of the spreader systems, their initial design intent, as well as the primary sources that make up the City’s stormwater. It bears repeating, the Chiquita Lock was NOT put in place solely because of septic tanks.

β€’ Removal of the Lock was found to impact the health of the mangrove fringe as well as habitats for two federally protected species: smalltooth sawfish and manatees.

β€’ FDEP estimated that removing the lock will introduce 30,000 lbs. of nitrogen per year into the Caloosahatchee.


The permit to remove the lock was granted by the state largely due to mitigation credits proposed by the City. These are on-paper estimates of nitrogen load reductions from a variety of other projects which may or may not prove effective.

🧫 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).
