U.S. Fish & Wildlife leaders have made the decision to close the lake where this bloom was detected in order to protect public safety and preserve the wildlife that lives in this area. Pets or humans can be exposed to the damaging effects of the cyanobacteria by contact with skin or water contaminated by the toxins.

This means that drinking, swimming in, eating exposed shellfish, or accidentally breathing in droplets of contaminated water can have damaging effects. Symptoms of exposure include stomach pain, vomiting, diarrhea, headaches, live pain, and neurological symptoms like dizziness or muscle weakness.

Therefore, anyone who visits the McNary Wildlife Refuge is advised not to swim, fish, boat or drink water from the area until further testing and prevention efforts ensure that toxins are reduced from the water. DCH officials say that the toxins generally remain in the water for a week after the cyanobacteria bloom is removed or disappears.
