Historic Floods Displace Thousands Across Four Corners States As Damage Surges

When the San Juan River Surged 13 Times Larger in 36 Hours

Intense rainstorms tied to an active El Niño-driven Pacific hurricane season left thousands displaced across the Four Corners states last week, with damage assessments trickling in from cities, towns, and remote tribal lands, reported. Colorado, New Mexico, Utah, and Arizona absorbed the brunt of the weather system, transforming normally dry terrain into rushing water channels.

Farmington and the San Juan River Basin

The northern New Mexico city of Farmington absorbed severe impacts after torrential rains pounded the San Juan mountains in Colorado. That runoff funneled directly into the San Juan River, which cuts through Farmington toward Lake Powell on the Utah-Arizona border. National Weather Service data from a local river gauge captured the scale of the rise: the San Juan expanded 13 times larger in just 36 hours late last week. In the early hours of Thursday morning, the river sat at roughly 3.5 feet. By Friday, it had climbed to 14 feet, flooding neighborhoods and threatening historic water levels.

The Navajo Reservoir upstream managed to contain much of the mountain runoff. However, downstream surges flooded the city via two normally dry tributaries, Gobernador Canyon and Cañon Largo. This is a catastrophic flood of historic proportions, said Devon Neeley, public information officer for San Juan County. This river got wider than we have ever seen it in our lifetimes.

Farmington, home to about 46,000 residents and a regional center for energy production and the northeast Navajo reservation, saw evacuation notices hit mobile phones starting Wednesday night. Connie Gooch, a resident of over 65 years, noted that her sister received evacuation orders on Thursday. While her sister regularly deals with rising seasonal waters by building sandbags, the speed of this surge left no time for defense. The river ultimately rose four feet inside her sister’s suburban home.

Widespread Regional Disruption Across the Four Corners

Similar devastation struck communities across state lines. In South Fork, Colorado, fire and rescue captain Tyler Schmidt reported that several neighborhoods sat under two to three feet of water along the banks of the Rio Grande. Colorado Public Radio’s Dan Boyce reported that recovery priorities include lifting remaining evacuation orders, assessing damaged bridges, and testing well water throughout the San Luis valley. Further south, Sedona, Arizona, faced sewage spills from flooded treatment plants, while KNAU detailed extensive damage on the Hopi reservation, which is surrounded by the Navajo nation.

Emergency responders deployed high-clearance National Guard units, amphibious vehicles, and rescue helicopters. San Juan County officials reported executing numerous rescues, pulling stranded motorists from running washes and lifting residents off rooftops.

Repair Costs Surpass Initial Estimates

By Sunday, rain subsided, and residents returned to pile damaged sheetrock and furniture on curbs. Yet public safety officials urged displaced residents to remain away due to lingering hazards. Stay out of the water. Gas, diesel, pesticides, fertilizer, these are not things that you want on your clothes.

On Monday, New Mexico Governor Michelle Lujan Grisham toured San Juan County and estimated that infrastructure repairs alone could reach between 200 and 300 million (dollars), far surpassing initial local estimates of 30 to 40 million (dollars). Following her visit, the governor announced that the federal government partially granted New Mexico’s emergency declaration request, while executive orders freed up an additional $8.25 million in state funding for ongoing flood response.
