"The Dry River fire grew to nearly 9,000 acres in just five days, requiring a large, multi‑agency response and demonstrating rapid expansion typical of extreme fire weather conditions. Its containment trajectory—from 0% to 90%—highlights the challenges of managing large, fast‑moving fires in rural Texas."
The Dry River wildfire, located 5 miles southeast of Sonora, TX in Sutton County, was discovered on September 15, 2026, and is caused by equipment and vehicle use under the jurisdiction of the SFS. The fire rapidly expanded from 400 acres at 21:20 UTC on September 15 to 8,939 acres by September 20, with containment rising from 0% to 90% over the five-day period. Early growth was explosive, reaching 3,500 acres by 04:00 UTC on September 16, and the fire entered an extreme, running phase with long‑range spotting until 07:20 UTC that day, when it had grown to 5,500 acres. By the evening of September 16, containment stalled at 25% despite 21 personnel, but additional resources increased the crew to 113 by 02:20 UTC on September 17, allowing containment to climb to 30% and later 40% as the fire shifted to a creeping, smoldering behavior. From September 17 onward, the fire size stabilized at 8,761–8,939 acres while containment steadily improved, reaching 85% by 21:40 UTC on September 19 and 90% by 01:00 UTC on September 20.
