Washington state's largest active wildfire, the Kaiser Canyon Fire, has grown to approximately 124,251 acres and remains just 15 percent contained as of July 30, 2026. The lightning-caused fire is burning on the Colville Reservation in Okanogan and Ferry counties, north-central Washington, and has prompted Level 1 through Level 3 evacuations for multiple communities including areas along the Columbia River.
Fire Origin
The Kaiser Canyon Fire ignited on July 16, 2026, following a lightning strike on the Colville Reservation near Nespelem. The fire spread rapidly in dry timber and grass fuels, driven by hot, dry conditions and periodic gusty winds that have been characteristic of this summer's fire weather pattern across the Pacific Northwest. As of late July, the fire was at zero percent containment before incremental progress was made by the more than 884 personnel assigned to the incident.
Evacuation Orders and Tribal Impact
The Confederated Tribes of the Colville Reservation have been significantly affected by the fire, with tribal members among those under mandatory evacuation orders. A Level 3 "Go" evacuation order has been issued for the Columbia River Campground and surrounding areas. Level 1 and Level 2 notices are in effect for a broader perimeter.
The Colville Tribal Emergency Management broadcast system has been coordinating evacuee support, and a shelter for displaced residents was established at the Lake Roosevelt Gym at 503 Crest Drive in the Coulee Dam area. Residents in affected zones are urged to heed all evacuation orders and monitor official tribal and county communications for updates.
Firefighting Efforts
More than 884 personnel are assigned to the Kaiser Canyon Fire. Crews are working to establish direct attack lines where terrain and fire behavior allow, while also constructing indirect lines and using natural barriers to limit fire spread toward populated areas and critical infrastructure. Aerial resources have been deployed when weather conditions allow effective retardant drops.
The fire has presented significant challenges due to its location in rugged canyon terrain on tribal lands, with limited road access to some portions of the fire perimeter. Coordination between federal agencies, the Colville Tribes, and state resources has been central to the suppression strategy.
Washington's Broader Fire Situation
The Kaiser Canyon Fire is the largest of Washington's 13 large active fires, which together have burned significant portions of eastern Washington. Nearly 150,000 acres have burned across land managed by the Washington State Department of Natural Resources (DNR) so far in 2026 — well above the 10-year average for this time of year. Other Washington fires include the Ptarmigan Fire burning near the Canadian border in the Pasayten Wilderness, and the Railroad Fire in Grant County, which destroyed at least seven homes and forced more than 1,000 people to evacuate last week.
