Residents across Jefferson County are waking up to hazy skies and unhealthy air this week as three significant wildfires continue burning on or near the Warm Springs Reservation. An Air Quality Advisory issued by the Oregon Department of Environmental Quality remains active through midday Friday, affecting Jefferson, Wasco, Crook, and several neighboring counties.
The Warm Springs Branch of Natural Resources logged a PM2.5 reading of 406 early Thursday morning — squarely in the "Very Unhealthy" range — one of the highest readings recorded in the region this season. Health officials are urging residents, particularly those with heart or lung conditions, children, the elderly, and pregnant women, to limit outdoor exposure and keep windows closed.
Where the Fires Stand
The Bench Fire, which scorched 67,079 acres, has reached 90% containment and officially transitioned command to Warm Springs Fire Management on August 10th. Incident commanders report zero active heat detection over the past week, with crews completing structure mop-up and perimeter security. The Bench Fire is widely considered the most significant blaze to burn on the reservation in recent years.
The Grasshopper Fire stands at 92,408 acres with 61% containment. Recent acreage jumps reflect internal burnout of unburned vegetation within the perimeter — not new growth — and mop-up continues extending 200 feet along the eastern flanks.
The Austin Fire presents the most active concern, mapped at 3,244 acres with 0% containment. Crews are navigating rugged terrain and heavy fuels, working to construct control lines along logging roads and drainages to protect critical utility infrastructure.
Protecting Yourself from Smoke
Tribal Health physician Dr. Michaela Frye is advising residents to take smoke exposure seriously, noting that fine particles can irritate lungs and eyes even during brief outdoor activity.
"Close your windows, replace HVAC filters, and avoid any indoor burning — including candles. If symptoms are severe, seek emergency care immediately."
Residents can monitor real-time air quality conditions at AirNow.gov or PurpleAir.com, and through the Warm Springs Natural Resources Department.
Stage 2 Fire Restrictions Still in Effect
Central Oregon public lands remain under Stage 2 public use fire restrictions, meaning all open fires are prohibited — including campfires, wood stoves, and charcoal fires — even within developed campgrounds and wilderness areas. The 2026 fire season has been in effect since May 8.
Jefferson County residents with questions about evacuation readiness or wildfire preparedness can contact the Jefferson County Sheriff’s Office or visit the Oregon Office of Emergency Management online. Those near active fire areas should sign up for emergency alerts through Jefferson County’s emergency notification system.
