Houghton Beach reopened for swimming and water activities as of 7:30 p.m. July 28, 2026, following confirmation from King County Public Health that bacteria levels have returned to safe levels. The closure began on July 7 after elevated bacteria were detected in water testing.
King County Water and Land Resources Division conducted tests this week and notified the city the waters were safe for recreational use. Crews will continue weekly testing throughout the summer to monitor water quality. Residents are directed to King County’s Lake Swimming Beach Data webpage for current status updates and to join the King County Lake Beach Alert mailing list for future notifications.
