The city directs visitors to water-quality status

Redmond lists the beach amenities and says to check the current water-quality status for swim safety, noting King County maintains those reports. King County says routine bacteria testing has ended for the season and will resume in mid-May (the year printed on the county page appears out of date). This guide keeps that live question separate from access permission.
