On July 23rd and 24th, Restore the Delta’s water quality testing program reported that HABs (Harmful Algal Blooms) have been found at Windmill Cove, Buckley Cove, and the Louis Park boat launch in Stockton.
Our test strips maxed out at 10 parts per billion, meaning actual toxin levels could be even higher. This exceeds California’s warning thresholds for public health and is the highest we’ve seen since 2022.
The current blooms look like chopped grass floating in the water—as if someone dumped a lawnmower bag into the water. You might also see it just below the surface.
What to do if you see HABS:
- Avoid HABs-infested areas, especially with children, the elderly, and pets
- Avoid skin contact or inhalation near or along the shoreline
- Do not ingest the water
Stay alert, stay safe, and help protect our Delta community by spreading the word.
