*KITSAP COUNTY, WA*

Cyanobacteria warning issued for Kitsap Lake due to potentially toxic cyanobacteria

"Cyanobacteria can make people and animals sick. Avoid all contact with the lake water."

________________________________________________________________________



*A cyanobacteria warning has been issued for Kitsap Lake.* Avoid all contact with the water in Kitsap Lake due to potentially toxic cyanobacteria [ [link removed] ], also known as blue-green algae.  

There are many different types of cyanobacteria and not all blooms are toxic. The cyanobacteria in *Kitsap Lake* are known to produce toxins.

Because cyanobacteria can make people sick [ [link removed] ] and can kill animals please:


* *Avoid all contact* with the lake water until further notice. This means no swimming, wading, or types of water play where water could be swallowed or get into your mouth, nose or eyes. 


* *Avoid drinking lake water*. If you use lake water for drinking water, use bottled water until further notice.


* *Keep pets and livestock out of the lake*.


* *Avoid eating fish* caught during the cyanobacteria bloom.


* *Rinse *boats and trailers thoroughly before going to another lake. 

No illnesses have been reported to Kitsap Public Health at this time.

Warning signs will be posted at public access areas around the lake. We will continue to monitor for cyanobacteria and post updates as conditions change. 

Park visitors are encouraged to sign up to receive [ [link removed] ] swimming beach advisories via email or text, and follow the Health District on Facebook [ [link removed] ] and X [ [link removed] ] for updates.
