The Big Grass fire, Oregon's largest wildfire in history, is now over 50% contained. The fire spans the Oregon-Idaho border.
Portland, OR, August 16, 2026 —
The Big Grass fire, which has become the largest wildfire in Oregon’s history, has reached a significant containment milestone, with over 50% of the blaze now under control.
The wildfire, burning across the border of Oregon and Idaho, has prompted extensive firefighting efforts from multiple agencies. While the exact acreage affected was not provided in the summary, its designation as the state’s largest wildfire in history indicates a substantial impact.
Containment figures are a critical measure in wildfire management, signifying the percentage of the fire’s perimeter that has been secured by firefighters, preventing further spread. The achievement of over 50% containment suggests that crews have made substantial progress in establishing control lines around the fire.
The cross-border nature of the Big Grass fire necessitates close coordination between Oregon and Idaho state agencies, as well as federal partners who often assist in managing large-scale incidents of this magnitude. The specific challenges and resources deployed to manage a wildfire spanning two states were not detailed in the provided summary.
Further updates on the containment status, acreage burned, and any impact on communities or natural resources are expected as firefighting operations continue.
