Juanita Beach is closed as of July 21, 2021 for at least one week due to elevated bacteria levels.

Water quality staff from the King County Water and Land Resources Division tested the water on Tuesday, July 20, and found that the levels of bacteria on the Eastern shore of the beach exceeded the thresholds for bacteria based on the average of the last three tests. King County crews will return to the beach next week to collect further samples. The beach at Juanita Beach Park will reopen when bacteria levels return to a safe range.

People and pets should not swim, drink lake water, or engage in other water activities at Juanita Beach, according to the city.

Signs will be posted to indicate that the beach is closed. City lifeguards will be onsite during the closure to communicate with beachgoers and provide information.
