Catastrophic Flooding Sweeps the Four Corners Region
By Drooid · · How we work
Core Event
On October 23, 2026, thunderstorms produced record runoff that caused the San Juan, Animas, Rio Blanco, Navajo, Piedra and South Fork Rio Grande rivers to overflow across southwestern Colorado and northwestern New Mexico. Rivers rose past flood thresholds, prompting mandatory evacuations, road closures and large-scale rescues. Floodwaters also breached the Bloomfield wastewater-treatment plant, turning the San Juan River into a raw-sewage “hazmat situation.”
Background & Context
The storm system moved east from Arizona, intensifying over the Four Corners. Earlier floods in 2025 had already strained local infrastructure, and officials called the October event “once in a generation.” The National Weather Service warned that additional storms could return Saturday.
Data & Statistics
- River crests: San Juan River hit 15.02 ft in Pagosa Springs (Archuleta County manager) and 23.17 ft in Shiprock (NWS). Animas River peaked at 10.6 ft in Cedar Hill.
- Evacuations: 30 people evacuated in San Juan County; at least 100 in southwestern Colorado; roughly 1,500 homes and buildings impacted in San Juan County.
- Rescues: 60 water rescues reported in San Juan County; a Colorado National Guard Black Hawk helicopter rescued two people and three dogs; New Mexico National Guard rescued an infant near Chaco Canyon.
- Infrastructure: U.S. Highway 160, Colorado Highway 17, the “Million Dollar Highway” (U.S. 550) and multiple county roads were closed or damaged. The Bloomfield plant shutdown released untreated sewage into the San Juan River.
Official Statements & Responses
- Governor Jared Polis declared a disaster emergency for eleven counties, activating the State Emergency Operations Plan and authorizing Colorado National Guard assets.
- Mayor John Mohler of Bloomfield urged residents to limit water use while the treatment plant remains offline.
- Sheriff Mike Le Roux reported “widespread catastrophic infrastructure damage” but no confirmed injuries or deaths as of midday Friday.
On-the-Ground Reports
Residents described sudden inundation of streets and homes. Bloomfield resident Kendal Luce recounted waiting for her husband trapped in a house with animals. Volunteers organized meals for responders, and the American Red Cross opened shelters at McGee Park (Farmington) and the Pagosa Lakes Property Owners Association clubhouse.
Conflicting Reports & Gaps
- River crest heights vary: 15.02 ft (county manager), 15 ft, and 23.17 ft (Shiprock, NWS).
- Evacuation counts differ: 30 people versus “at least 100.” No consolidated total exists for the region.
- Damage assessments remain incomplete; officials continue to evaluate destroyed structures.
Verbatim Quotes
- “Our first priority is the safety of our residents and employees. I’m grateful for the work of our police officers, utility personnel, emergency responders, and everyone helping our community through this flooding. We’re asking residents to do their part by limiting wastewater discharge until our treatment facility can safely resume operations. Every little bit helps,” — Mayor John Mohler
- “With the breach of the sewer system in Bloomfield, the San Juan River is a hazmat situation.” — Devin Neeley
What’s Next
The National Weather Service forecasts continued heavy rain through Saturday, sustaining river levels and limiting road-assessment crews. State and local agencies will monitor gauges and may issue additional evacuation orders if waters rise. The disaster-emergency declaration enables federal assistance, and the Colorado National Guard remains on standby for further rescue and recovery.
