Florida issued freshwater cyanobacteria advisories in the first week of January 2026. Months later, the same nutrient-rich lakes and canals keep blooming. Florida no longer has a summer freshwater bloom season; it has a year-round one.
On April 23, 2026, volunteers confirmed the earliest harmful algae bloom on record at Cayuga Lake in upstate New York. In 2025, the first bloom did not appear until July 5. The 73 day shift has serious implications for Northeast lake managers.
Are 'cyanobacteria,' 'blue-green algae,' and 'harmful algal blooms' the same thing? Mostly — but the distinctions matter for treatment decisions, regulatory compliance, and public communication. Understanding the vocabulary is step one. Taking biological action is step two — order Hydralife's live phytoplankton at hydralife.org.
