What a satellite can and can’t tell you

Satellites see only the surface layer, only on cloud-free days, and only away from the shoreline. They estimate algae; they do not measure toxins, and they can’t see what the lake bottom is doing. A clear reading is not a safety clearance.

For current conditions and health advisories, check the Florida DEP algal bloom page and the Florida Department of Health. If a person or pet may have been exposed to a bloom, call a doctor, a veterinarian, or Poison Help at 1-800-222-1222.

Source: Sentinel-2 MSI (ESA Copernicus), Red-edge cyanobacteria index (CI-cyano); a scene counts as a bloom when the index is above 50 and stays high relative to turbidity (bloom rule v1 (2026-10)). Snapshot exported Oct 9, 2026.
