As of 4:12 p.m. on Sept.15, 2026, Public Health - Seattle & King County is recommending that people and pets stay out of the water at the swimming areas of Juanita Beach Park for at least one week due to elevated bacteria levels. Signs will be positioned to indicate that the swimming area is closed. The rest of the park remains open.

Additionally, Houghton Beach has been reopened for swimming, wading, and other water activities, by recommendation of Public Health - Seattle & King County. The beach had been closed to swimming since Sept. 9 due to elevated bacteria levels.

Water quality staff from the King County Water and Land Resources Division tested the water recently and found that the levels of bacteria at these beaches exceeded safe thresholds for bacteria based on the samples collected. King County crews will return to the beaches next week to collect further samples.

For additional details, visit King County's Lake Swimming Beach Data webpage.

Updates about Juanita Beach Park will be posted on the City's website.

Why are the swimming areas closed? Swim beaches throughout King County are tested weekly by the King County Department of Natural Resources and Parks. If beach water tests high for bacteria, the swimming area will be closed. For testing information or to see which beaches are open/closed, please visit the King County Lake Swimming Beach Bacteria page.
