# Colorado Aspen Acres wildfire and subsequent flood risks > Live situation record from CLSTR: https://clstr.news/situations/colorado-aspen-acres-wildfire > Updated: 2026-08-22T21:38:00.000Z. Sources: 9. Developments: 4. In mid‑July 2026, the Aspen Acres fire in Pueblo and Custer counties became the seventh‑largest wildfire in Colorado history, burning more than 99,000‑101,000 acres and destroying over 300 homes and 800 structures. By July 17, the blaze was about 61% contained, prompting a multi‑agency mutual‑aid response and an emergency power shutoff near the smaller Big Gulch fire. Colorado lawmakers passed insurance reforms to speed claim processing for affected homeowners, and the disaster‑tracking app Watch Duty saw increased use. Five days later, containment remained at 61% while crews continued bulldozer lines, hand crews, and aerial support. A new quarter‑acre “Salt fire” ignited nearby and was being encircled with defensive lines. The National Weather Service issued flash‑flood warnings for the burn scar, warning of rapid runoff, debris flows, and possible road washouts in communities such as Beulah. Residents were urged to avoid flood waters and prepare for further hazards. By mid-August, the threat of flooding persisted as the National Weather Service issued multiple flash flood warnings and watches across southeastern Colorado. Heavy thunderstorms threatened the Middle Aspen Acres Burn Scar, spanning Custer, Fremont, Huerfano, and Pueblo counties. Forecasters warned that excessive rainfall could trigger life-threatening debris flows of rock, mud, and vegetation through several drainages, including North Saint Charles, South Creek, Squirrel Creek, Middle Creek, and North Creek. High-risk areas included Beulah, Highway 165, and Highway 78, while a separate flash flood warning was issued for the Purgatoire River Basin in Northeastern Las Animas County. By late August, life-threatening flash flood warnings continued for Custer and Pueblo Counties due to heavy rain over the Middle Aspen Acres Burn Scar. Debris flows were expected through several drainages, with high-risk areas identified in Beulah and San Isabel. ## Claims - The National Weather Service issued flash flood watches and warnings across southeastern Colorado.
