Summary

Heavy rainfall in the Four Corners region triggered historic flooding in San Juan County, New Mexico, and 12 southwest Colorado counties in late October 2026. The San Juan River exceeded its 1909 record height, while the Animas River reached levels comparable to 1927 and 1941. Thousands of residents were evacuated from approximately 1,500 residences, with emergency crews conducting between 60 and 300 water rescues. Hundreds of homes and structures sustained damage, with estimated costs reaching $27.1 million. One person was injured. No deaths were reported. The neighborhood remains flooded, and a shipping container was observed drifting down a street. Governors Michelle Lujan Grisham of New Mexico and Jared Polis of Colorado declared states of emergency and requested federal disaster declarations. The Colorado National Guard and New Mexico State Police assisted with evacuations and rescue operations. Road closures, power outages in Shiprock, and water quality concerns from untreated wastewater affected the region. Emergency shelters were established at McGee Park and San Juan College.
