The Kitsap Public Health District issued a cyanobacteria warning July 16 for Horseshoe Lake in Port Orchard.

The public is advised to avoid all contact with water in the lake Lake due to the presence of potentially toxic cyanobacteria, also known as blue-green algae, per KPHD. Because toxic cyanobacteria can make people sick, and can kill pets, fish, waterfowl and livestock, the public is advised to:

• 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 in the mouth, nose or eyes (especially in areas where blooms are concentrated).
• Avoid ingesting lake or stream water. If a resident draws lake water for drinking purposes, they are encouraged to drink bottled water until further notice.
• Limit access of pets and livestock to the lake.
• Avoid eating fish caught during the algae bloom.
• Rinse boats and trailers thoroughly before going to another lake.

No illnesses have been reported to KPHD at this time. Advisory signs will be posted at public access areas and roadsides around the lake. The health district will continue to monitor for cyanobacteria post updates as conditions change.
