Approximately 3,000 gallons of sewage spilled into Kitsap Lake Monday, prompting a no-contact advisory through Dec. 29, according to the Kitsap Public Health District.

The existing cyanobacteria (blue-green algae) warning from August will remain in effect until further notice. During a no-contact advisory, the public is advised to avoid contact with water in the affected area.

The health district recommends against swimming, wading, or types of water recreation that could cause water to be swallowed or get into the mouth, nose, or eyes. People are also advised to avoid direct skin contact if possible and immediately wash with soap and clean water if they are exposed to the water.

Advisory signs will be posted at public access points. For more information, visit kitsappublichealth.org/beaches.
