Update: Medina Beach Park re-opens to water access; tests show no health threat


Medina Beach Park re-opened to water access on Monday, Dec. 23, after multiple water-quality tests following a Dec. 20 wastewater overflow showed no public health threat.


Public water access resumed at midday on Monday, Dec. 23 at Medina Beach Park following two consecutive days of water-quality tests indicated the water was safe after a brief wastewater overflow during a record rainstorm on Friday, Dec. 20.

Laboratory results from Lake Washington water sample tests taken at multiple locations around Medina Beach Park on both Dec. 21 and Dec. 22 were at levels below the state public health thresholds.
King County reported a sewer overflow at the Medina Pump Station from about 2:30 p.m. to about 6:30 p.m. on Friday Dec. 20 – during the height of the rainstorm that resulted in record rainfall across the county.
