The Chelan-Douglas Health District Board of Health declared a Wildfire Smoke and Hazardous Air Quality Emergency on August 6, 2026, for Chelan and Douglas counties.
The declaration recognizes health risks from prolonged wildfire smoke exposure and provides guidance for event organizers, employers, and residents. Event organizers should consider AQI levels, higher-risk populations, and indoor alternatives. Residents are advised to limit outdoor activity, use HEPA air cleaners, and seek clean air shelters like North Central Regional Library branches.
CDHD recommends actions based on Air Quality Index levels: AQI 101β150 (Unhealthy for Sensitive Groups), AQI 151β200 (Unhealthy), and AQI 201+ (Very Unhealthy/Hazardous).
