Satellite estimate (not an advisory)
Week ending Oct 17, 2026: about 350,000 cells/mL of cyanobacteria near the center of Clear Lake.
A satellite estimate from EPA CyAN for a 160.5 km² lake. It does not measure toxins and does not change the advisory status.
| Week ending | Estimate |
|---|---|
| Oct 17, 2026 | about 350,000 cells/mL |
| Oct 10, 2026 | about 550,000 cells/mL |
| Oct 3, 2026 | about 510,000 cells/mL |
| Sep 26, 2026 | about 400,000 cells/mL |
| Sep 19, 2026 | about 510,000 cells/mL |
| Sep 12, 2026 | about 650,000 cells/mL |
| Sep 5, 2026 | about 550,000 cells/mL |
| Aug 29, 2026 | about 510,000 cells/mL |
This is a satellite estimate from the U.S. EPA's Cyanobacteria Assessment Network, not an advisory. It estimates how much cyanobacteria is in the water near the lake's center, not whether toxins are present: a high number does not mean toxins, and a low one does not mean there are none. It covers lakes of about 1 square kilometer and larger, so small ponds, dog parks and most rivers are not covered, and clouds can hide a lake for weeks. It never changes the advisory status above.
Satellite estimates: U.S. EPA Cyanobacteria Assessment Network (CyAN), from Copernicus Sentinel-3 data. Provisional, research-level estimates; EPA does not endorse this site. Checked Oct 22, 2026.
