More than 12,000 wildland firefighting personnel remain assigned to active incidents across the country as the 2026 fire season continues into mid-September. The National Interagency Fire Center reported that as of September 18, firefighting forces nationally included 229 crews, 625 engines, and 70 helicopters — a substantial mobilization reflecting the extraordinary scale of this year's fire activity.
Pacific Northwest Mutual Aid
Throughout the 2026 season, Washington's Department of Natural Resources relied heavily on mutual aid from neighboring states through the Northwest Compact — a regional agreement allowing states to share firefighting resources during periods of high demand. The compact proved critical during the peak of summer fire activity, when multiple simultaneous large fires stretched Washington's own firefighting capacity to its limits.
"We saw a lot of extreme fire weather events that moved through Washington and the Pacific Northwest, and we saw multiple large, costly fires develop on the landscape," said DNR Public Information Officer Ryan Rodruck. "I think Spokane, due to the scale of the devastation, is one that is going to stick out in people's memories."
Among the most resource-intensive incidents this season were the Spokane-area fires, the Little Giant Fire (172,695 acres) in Chelan County, the Three Queens Fire (9,527 acres) in Kittitas County, and the Sinlahekin Fire (166,000 acres) in Okanogan County.
Ongoing Idaho Incident Demands
In Idaho, several fires continue to demand active suppression resources. The Parker Lake Fire — 20 miles northwest of Bonners Ferry in the Idaho Panhandle — has zero containment as of mid-September, requiring continued crew and aerial support. The Silver Fire in the Idaho Panhandle National Forest covers 2,593 acres with 30% containment, while the Cascade Fire near Lowell covers 7,475 acres at 50% containment. The Crooked Fire, 14 miles northeast of Idaho City, is at 10,081 acres and 93% contained, approaching final mop-up.
Aviation Resources
Aviation assets played a critical role throughout the 2026 season in the Pacific Northwest. Air tankers were extensively deployed to the Little Giant and Three Queens fires in Washington, as well as to multiple large Oregon incidents during their peak activity phases. Helicopter operations proved particularly important for reconnaissance, crew transport, and structure protection in areas where ground access was limited by terrain or active fire conditions.
The national aviation fleet of 70 helicopters currently assigned to incidents represents a significant commitment of one of the most flexible and high-demand resources in wildland fire response.
Firefighter Safety and Fatigue Management
With 12,000-plus personnel still in the field nationally — many of whom have been working extended assignments since the height of the season in July and August — agency leadership continues to emphasize firefighter safety as a top priority. Extended operational periods, cumulative fatigue, and the transition to fall weather patterns, which can bring rapidly changing wind conditions, require heightened situational awareness as crews move through mop-up and patrol phases.
The 2026 season has placed extraordinary demands on the nation's wildland fire workforce. As the season enters its final stretch, agencies are beginning post-incident reviews to identify resource gaps, staffing needs, and equipment improvements that should be prioritized heading into 2027.
