Archuleta County in southwestern Colorado is experiencing urban and small stream flooding due to excessive rainfall. The National Weather Service (NWS) issued a Flood Warning for the county on October 23, 2026, from 7:28 AM MDT until 9:45 AM MDT. Between 1.5 and 3 inches of rain had already fallen, with an additional 0.5 to 1 inch possible.

Flooding is ongoing or expected to begin shortly in the warned area. Rivers, creeks, streams, and other low-lying and flood-prone locations are experiencing flooding. This has resulted in several structures being flooded and numerous roads remaining closed county-wide. Some of the affected locations include Pagosa Springs, Lonetree, Chimney Rock, Juanita, Gato, and Pago.

Mandatory evacuation orders have been issued for low-lying and flood-prone areas along several rivers. The Archuleta County Sheriff's Office (ACSO), along with Pagosa Springs, initiated these evacuations along the San Juan River, Rio Blanco River, Navajo River, and Piedra River. Local authorities ordered residents and travelers in vulnerable zones to evacuate immediately as swift-moving waters breached channel banks.

Road closures are affecting various parts of the county. The Colorado Department of Transportation (CDOT) reported that Highway 160 was closed between Wolf Creek Pass and South Fork after floodwaters covered the road. CO 151 is also closed south of the US 160 junction. Within Pagosa Springs, Hermosa Street and San Juan Street are closed. ACSO stated that North Pagosa Boulevard from around Gate 5 to the top of the split past Coronado Circle was closed, and County Road 500 is closed from mile marker 12 to Highway 151.

The San Juan River at Pagosa Springs is expected to rise to 13.7 feet, which is over a foot above major flood stage, by approximately 4 a.m. Friday. Archuleta School District schools were closed on Friday, October 23. A resident in Pagosa Springs reported a power outage in the downtown area early Friday morning. This resident also noted McCabe Creek had overflowed its banks, appearing to flood part of the neighborhood. Sandbags are available at the Archuleta County Building and the Tara Community Center. The flooding in Archuleta County is occurring as "Super El Niño Storms" affect Colorado and the Southwest.
