Blue-green algae alert issued
- Florida health officials issued a new blue-green algae alert for the Caloosahatchee River–Sebastian Canal near Alva Boat Ramp after this week’s sampling found toxins. - The alert followed water samples collected Tuesday, and officials said people should avoid drinking, swimming, wading, boating, or letting pets near bloom water. - This stretch already saw alerts lifted in late January and mid-February, showing how quickly toxin conditions can return.
Blue-green algae is back in a familiar stretch of Lee County water — and that matters because this is the kind of hazard that looks local but can disrupt everyday river use fast. The Florida Department of Health in Lee County issued a fresh health alert for the Caloosahatchee River–Sebastian Canal area near the Alva Boat Ramp after samples collected Tuesday tested positive for harmful algae toxins. That means the warning is not just about ugly water. It is about toxins that can sicken people and kill pets. ### Where is the alert? The alert covers the Caloosahatchee River–Sebastian Canal area in Lee County, near the Alva Boat Ramp. That is an inland freshwater corridor people use for boating, fishing, and shoreline access, so even a narrow alert can affect a lot of normal weekend activity. ### What actually triggered it? A water sample collected on Tuesday tested positive for harmful blue-green algae toxins. (gulfcoastnewsnow.com) That is the key threshold here — Florida does not issue these health alerts just because water looks suspicious. The alert goes out after toxin testing confirms the risk. ### What are people supposed to avoid? Basically, anything that puts you or your animals in contact with bloom water. (gulfcoastnewsnow.com) Health officials said do not drink it, swim in it, wade in it, use personal watercraft in it, or touch water where there is a visible bloom. If you do get exposed — or even touch discolored or foul-smelling water — wash skin and clothing with soap and water right away. Pets and livestock should be kept away entirely. ### Why is boiling not enough? Because the problem is the toxin, not just the organisms floating in the water. Health officials said contaminated water should not be used for cooking or washing dishes, and boiling will not remove the toxins. That catches people off guard, because “just boil it” is the usual instinct with water problems. Here, that fix does not work. (lee.floridahealth.gov) ### What does blue-green algae even mean? It is not really algae in the everyday sense. It is cyanobacteria — bacteria common in Florida freshwater. When conditions line up, the bacteria multiply fast and form blooms that can discolor water, create surface scum or mats, and give off a bad smell. The big drivers are warm water, sunny weather, still conditions, and excess nutrients. (lee.floridahealth.gov) ### Why does this spot keep coming up? Turns out this is not the first alert there this year. Lee County issued an alert for the same Caloosahatchee River–Sebastian Canal area in late January, reissued one on February 5 after another toxin-positive sample, then lifted that February alert on February 13 after follow-up testing found no toxins. So this is a reminder that blooms are not a one-and-done event — they can fade, clear, and return quickly when conditions swing back in their favor. (lee.floridahealth.gov) ### How do people track whether it clears? Florida pushes results through the Protecting Florida Together notification system and the DEP algal bloom dashboard. The state also says people can report suspected blooms online or by phone, which matters because bloom conditions can change before the next headline does. ### Bottom line For now, this is a simple rule: stay out of bloom water near Sebastian Canal and keep animals out too. (lee.floridahealth.gov) The bigger story is that Lee County has now seen this same area cycle through alerts, lifts, and another alert within a few months — which is exactly why these warnings matter.
