No Anatoxin was detected from the Roy Rook Boat ramp in the Klamath Glen or from samples in the estuary.  

Extra care should be taken to avoid accidentally swallowing river water.  

Do not enter the river if you have cuts or abrasions on your skin. 

Use caution when entering the river at slow flowing areas or in back eddies, as algae and toxins may concentrate in these areas and be unsafe.

According to Yurok officials, blue-green algal blooms are often patchy in nature, which may limit extensive sampling in all areas.
