Environmental scientists collect water samples each week from all King County lake beaches and test them for bacteria. Our scientists look through the data for potential public health risks. Depending on the results, we close or open beaches to keep people safe. This year, we’re changing how we make beach closure and reopen decisions. These changes are in line with the latest science.
By now you may have heard that we’re experiencing high cases of flu and RSV (a respiratory disease) (in-language resources available) this fall, with young children being hospitalized. With cold weather, we spend more time inside. This increases the potential for another surge of COVID-19 cases and hospitalizations in the coming months.
Diseases like RSV, the flu, and COVID-19 are airborne and spread easily indoors. With that in mind, it’s important to pay attention to indoor air quality.
