Kitsap Lake swimming beaches temporarily closed due to E.coli
August 09, 2018
Existing cyanobacteria (blue-green algae) warning for the lake remains in effect
(KITSAP COUNTY, WA.) -- On Wednesday the Kitsap Public Health District closed the swimming beach at Kitsap Lake due to high levels of E. coli bacteria in the water.
The public has been advised to avoid swimming in Kitsap Lake since July 10 when the Health District issued a cyanobacteria (blue-green algae) warning.
Elevated E. coli levels
“With elevated E. coli levels there is an increased risk of getting sick so the the public is advised to continue to avoid all contact with the water at the swimming beach until further notice,” said a statement by the health agency. “This means no swimming, wading, or types of water play where water could be swallowed or get in the mouth, nose or eyes. The risk of illness is greatest for young children, the elderly, or anyone with a compromised immune system.”
The closure level for E. coli is a geometric mean value (GMV) of 126 MPN/100 mL. For samples taken Tues, August 7 at the Kitsap Lake Park swimming beach, the GMV was 2419 MPN/100 mL.
MPN/100mL is a unit of measure and stands for the "most probable number" of bacteria colonies that grow in a 100mL sample.
Cyanobacteria (blue green algae)
Due to the continuing cyanobacteria bloom in Kitsap Lake, the cyanobacteria warning for the lake issued July 10 is not likely to be lifted anytime soon. Because toxic cyanobacteria can make people sick, and can kill pets, fish, waterfowl and livestock, the public is advised to:
Avoid all contact with Kitsap Lake 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 the algae 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.
Exercise caution when considering eating fish caught in the lake as toxins can accumulate in fish tissues, especially in the liver, kidneys and other organs. Before eating, remove internal organs, which may contain more of the toxin.
Rinse boats and trailers thoroughly before going to another lake.
Kitsap Public Health will continue to monitor the Kitsap Lake Park swimming beach for both cyanobacteria and E.coli. No illnesses have been reported to Kitsap Public Health at this time.
