The Little Giant Fire in Chelan County, Washington continues to be one of the most dangerous active fires in the Northwest, burning 142,218 acres at just 15% containment as of August 23, 2026, according to the National Interagency Fire Center. The fire is burning within the Okanogan-Wenatchee National Forest, roughly 30 miles northwest of Leavenworth, and has been steadily growing since its discovery on July 16.
As of this week, current wildfires trackers report the fire averaging an estimated 3,714 acres of daily growth — an alarming rate that underscores the extreme fire conditions persisting across the eastern Cascades.
Communities Under Threat
The fire has threatened 1,824 structures at various points in its growth and has generated some of the worst air quality readings of the 2026 season across the Leavenworth area. Communities downwind — including Cashmere, Entiat, Manson, and Plain — have experienced repeated episodes of hazardous air quality from smoke transported by drainage winds off the Cascade Range.
Level 3 "Go Now" evacuation orders have been in effect for portions of the Chiwawa and Tyee ridges and Chelan Mountains. Residents in affected areas are urged to leave immediately and not wait for conditions to worsen.
At the height of the fire's growth in early August, the blaze jumped Lake Chelan, one of the deepest lakes in North America, illustrating the extraordinary spotting potential of the fire under high-wind conditions.
Firefighting Operations
More than 1,000 firefighting personnel have been assigned to the Little Giant Fire at various stages of the response. Helicopters, water scoopers, and heavy air tankers have been working the perimeter, dropping water and retardant on advancing fire fronts. Northwest Team 12 assumed command of related fires west of Stehekin — including the Sisi and Agnes fires — in mid-August.
The low containment percentage reflects the fire's remote terrain and continued active behavior. Until temperatures moderate and relative humidity recovers, firefighters are focused primarily on structure protection and keeping the fire away from communities rather than direct attack on open perimeters.
Smoke and Air Quality
The Little Giant Fire has produced heavy, persistent smoke that has impacted communities well beyond Chelan County. Air quality monitors have recorded AQI readings well into hazardous territory near Leavenworth during peak smoke days. Officials advise residents to stay indoors when AQI exceeds 150, use air purifiers if available, and wear N95 or better masks if outdoor activity is unavoidable.
