Juanita Beach is closed for at least one week due to elevated bacteria levels, according to the City of Kirkland.

Water quality staff from the King County Water and Land Resources Division tested the water on Tuesday, June 29, 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.

On Tuesday a bacterial geometric mean was measured at 217 colony forming units per 100 ml. Measurements from the two previous weeks were 188 CFU/100ml on June 22 and 102 CFU/100ml on June 15.

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 King County’s water quality standards.

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