Warning Posted For Lake Wilderness Cyanobacteria Bloom Toxins

Warning signs are being posted at Lake Wilderness swimming beach due to a Cyanobacteria bloom that is producing toxins. Toxicity results from samples taken at the swimming beach on Monday, where minor bloom scums were observed, indicated the presence of toxins at levels above the Washington State’s recreational guideline.

Cyanobacteria bloom toxins can threaten the health of people and pets if contacted or ingested.

Contact with visible scum formations should always be avoided. Young children and pets are particularly at risk.

Young children playing at the shoreline may contact the scum or get it in their mouths and pets may drink it or lick it off their fur.

Common symptoms include nausea, vomiting, diarrhea, and eye or skin irritation. If water with visible scum is contacted or ingested, notify your doctor or veterinary immediately and follow their instructions.
