Rowe Creek Complex: Nation's Largest Active Wildfire Burns 143,000 Acres in Central Oregon

The Rowe Creek Complex has exploded to nearly 143,000 acres and remains at zero percent containment, earning the grim distinction of being the largest active wildfire in the United States as of July 20, 2026. Burning across Wheeler and Wasco counties in the rugged terrain of central Oregon near the John Day River, the complex is testing the limits of firefighting capacity in the Northwest Geographic Area.

Fire Origin and Behavior

The Rowe Creek Complex ignited on July 15, believed to have been sparked by lightning during the same series of dry thunderstorms that set off dozens of other blazes across the Pacific Northwest. The most significant fire in the complex is burning through a mixed fuel matrix of grass, brush, and timber — conditions that enabled rapid and aggressive spread from the initial ignition.

InciWeb data shows the fire growing to 142,936 acres by the afternoon of July 20, with firefighters struggling to establish any meaningful containment lines on a fire that continues to run in dry, windy conditions. No containment percentage has been achieved as of the latest update.

Evacuation Situation

The rapid growth of the Rowe Creek Complex has forced emergency managers in Wheeler and Wasco counties to issue a full range of evacuation levels. According to Central Oregon Fire Information, Level 1 (Be Ready), Level 2 (Be Set), and Level 3 (Go Now) notices are all currently in place for communities near the active fire perimeter.

Residents in affected areas are urged to treat any evacuation level seriously, as fire behavior in these conditions can shift rapidly. Level 3 means leave immediately — do not wait for additional notice.

Oregon Emergency Response

Governor Tina Kotek invoked the Emergency Conflagration Act on July 17 for the Rowe Creek Complex in Wheeler County, authorizing the Oregon State Fire Marshal to mobilize structural protection task forces and incident management resources statewide. This was the fourth time the act had been invoked in Oregon in just over a week.

The Oregon State Fire Marshal deployed its Red Incident Management Team alongside structural task forces to assist local resources and provide coordinated command of what has become an extraordinarily complex and dangerous fire environment.

Firefighting Challenges

The terrain in Wheeler and Wasco counties — a mix of canyon lands, rimrock, and rolling rangeland — presents significant challenges for ground crews attempting to build fireline. Air resources have been a critical part of the response, though high smoke columns and turbulent fire-generated winds can limit aerial effectiveness during periods of peak fire activity.

The Rowe Creek Complex is burning in the same broader region as several other active fires, compounding the resource demand picture for the Northwest Geographic Area, which is already stretched to capacity.

What to Expect

Forecast conditions through the remainder of the week do not offer significant relief. The National Weather Service has issued Red Flag Warnings for portions of central Oregon through at least July 22, with additional dry thunderstorms, gusty outflow winds, and relative humidity values dropping to critically low levels in the forecast. Any new lightning starts near the Rowe Creek Complex perimeter could complicate containment efforts further.
