Washington's Largest Fires Winding Down as Crews Mop Up Hundreds of Thousands of Acres

Washington State firefighters are entering the mop-up phase on what has been one of the most destructive fire seasons in the state's recorded history, with more than 413,000 acres burned across roughly 20 active fires as of October 8, 2026. While the most dangerous burning conditions of the season appear to have passed, several significant incidents remain active — including one fire still at just 29 percent containment near the remote community of Stehekin.

Little Giant Fire: 172,906 Acres, 93% Contained

The Little Giant Fire in Chelan County remains the largest active incident in Washington, having scorched nearly 173,000 acres across the Okanogan-Wenatchee National Forest about 30 miles northwest of Leavenworth. Managed by a Complex Incident Management Team (CIMT NW Team 12), crews are dealing with smoldering, creeping, and backing fire behavior in timber and dormant brush as fall weather moderates conditions. Road and trail closures remain in effect throughout the fire perimeter. The U.S. Forest Service can be reached at 509-776-6953 for the latest updates.

Sinlahekin Fire: 166,007 Acres, 99% Contained

The Sinlahekin Fire in Okanogan County — located about 12 miles west of Tonasket and managed by the Washington State Department of Natural Resources — is approaching full containment at 99 percent. At more than 166,000 acres, the Sinlahekin ranks as one of the largest fires in Washington history. Contact information: 509-287-4942.

Sisi Fire: Still Active Near Stehekin

The Sisi Fire continues to burn on the Okanogan-Wenatchee National Forest about 10 miles northwest of the remote lakeside community of Stehekin, where no road access exists. At 4,385 acres and only 29 percent contained, the fire ignited on August 14, 2026 — likely from natural lightning — and has been burning for more than 50 days. Fire behavior has been minimal, with firefighters reporting smoldering, creeping, and backing activity in timber litter. Still, the fire's proximity to Stehekin means crews are maintaining a close watch. Area, road, and trail closures remain in place.

High Lava Fire Near Full Containment

The High Lava Fire in Skamania County has reached 95 percent containment after burning approximately 2,899 acres. Crews continue mop-up operations in that area of southwest Washington.

Looking Ahead

Cooler temperatures and increased moisture arriving with fall weather systems are expected to aid firefighting efforts across the state. The National Interagency Coordination Center has dropped Washington's geographic area preparedness level as the most critical fire weather has passed for the season. Residents near active fire areas should continue to monitor local emergency management channels for any changes to evacuation orders or trail and road closures.
