Lake swimming beach bacteria and temperature

During the summer, we test the water for bacteria at many lake beaches in King County. Routine water testing has ended for 2024 and will resume in mid-May 2025. Check back next summer to find a healthy beach!   Rainy Season Safety Swim safely during the rainy season! Stay out of the water for 24 hours after heavy rainfall. When it rains, poop and germs get washed from land into the water.  Keep an eye out for harmful algae blooms, which can make people and animals sick. Some types of harmful algae can grow more in the fall.  Learn more about how to stay safe around harmful algae blooms by watching this video from the CDC: You can find the most recent data for toxic algae in Washington at nwtoxicalgae.org. And the table and map below will continue to show any beaches or lakes that are closed due to toxic algae. Also check the Combined Sewer Overflow website, to see if a combined sewer overflow is occurring before going swimming, wading, fishing or boating. Stay out of the water near an overflow for 48 hours after a sewage and stormwater overflow.
