Intense rainstorms fueled by an active El Niño-driven Pacific hurricane season have left thousands displaced across the Four Corners states, triggering historic river surges that caught communities from Colorado to Arizona by surprise. As waters begin to recede, damage assessments are rolling in, with New Mexico Governor Michelle Lujan Grisham estimating that infrastructure repairs alone in her state will reach between $200 and $300 million.
A River Multiplied by Thirteen in Hours
The northern New Mexico city of Farmington bore the brunt of the regional deluge after torrential downpours hammered the San Juan mountains in Colorado, funneling immense volumes down the San Juan River. According to National Weather Service data from a river gauge in Farmington, the waterway swelled 13 times larger in just 36 hours late last week. Early Thursday morning, the gauge measured the river at about 3.5 feet. By Friday, it had climbed to 14 feet, likely setting a water-height record for the city.
KVCR reported that the surging waters arrived even though the Navajo Reservoir upstream managed to contain much of the runoff from the mountains. Downstream of the reservoir, however, massive flood surges poured into Farmington from two normally dry tributaries, Gobernador Canyon and Cañon Largo.
“This is a catastrophic flood of historic proportions,” said Devon Neeley, San Juan County’s public information officer, as reported by KVCR. “This river got wider than we have ever seen it in our lifetimes.”
Rescues Across the Four Corners
The crisis extended far beyond Farmington. Small towns positioned along the river corridor, including Pagosa Springs in Colorado, Bloomfield in New Mexico, and Bluff in Utah, faced severe recovery challenges. On the western slope of the San Juan mountains in Colorado, Captain Tyler Schmidt of the South Fork fire and rescue team noted that neighborhoods were submerged under two to three feet of water, describing conditions unlike anything local responders had previously witnessed.
In New Mexico, San Juan County officials mobilized an extensive rescue operation involving police, fire crews, National Guard troops, and out-of-state swift water teams. Residents were pulled from stranded vehicles, flooded roadways, and rooftops using high-clearance military vehicles and amphibious craft.
Further south, the impacts compounded across tribal lands. KNAU reported extensive damage on the Hopi reservation, while the surrounding Navajo reservation experienced washed-out roads, isolated flooding, and emergency rescues. Sewage treatment plants in Sedona, Arizona, and other locations suffered spills, raising acute concerns over drinking water safety and well contamination down the Rio Grande’s path in the San Luis Valley.
Weighing the Recovery Costs
By Sunday, the rainfall had eased and water levels began dropping, allowing displaced residents to return and confront the destruction. Connie Gooch, a Farmington resident of more than 65 years, described neighborhoods filled with families clearing out ruined drywall and piling sodden furniture onto the curb. Her own sister’s suburban home near the river took on four feet of water.
Despite residents’ eagerness to return, local officials urged caution. San Juan County officials warned at a Sunday briefing that receding waters exposed a fresh wave of dangers, including live power lines, compromised gas lines, and raw sewage contamination.
On Monday, Governor Lujan Grisham toured San Juan County to evaluate the destruction firsthand. While local managers initially projected costs between 30 and 40 million, the governor warned that the total price tag for environmental restoration, road repairs, and structural rebuilding would climb much higher.
Later that evening, Lujan Grisham announced that the federal government had partially granted New Mexico’s request for an emergency declaration. That action followed her signing of executive orders releasing an additional $8.25 million in state funds to support ongoing flood response efforts.
