Farmington's Gatewave Returns to Action After Months of Sediment Buildup

Kayakers and river surfers were back on the Gatewave at Gateway Park as of April 3, ending a months-long shutdown that began when a fall 2025 flood event drove the Animas River to nearly 6,500 cfs, deposited a wave-killing load of sediment in the riverbed downstream of the feature, and raised the water level enough to erase the hydraulic entirely.

The Gatewave had opened just last July as the Four Corners region's first engineered river surf wave. The $2.6 million project drew its primary funding from a $2 million allocation from the New Mexico Office of Natural Resources tied to the Gold King Mine spill settlement, with the remainder split between a State Trails Plus Grant and Community Transformation and Economic Diversification funds. Mayor Nate Duckett and city officials had positioned the feature as a centerpiece of Farmington's outdoor recreation identity. By November 2025, sediment and debris buildup had reduced the wave to a trickle.

The flow event carried large volumes of sediment down the river, much of which settled in the riverbed just downstream of the wave, raising the water level below the feature and killing the hydraulic jump. The sediment needed to be cleared and the downstream gravel bar repaired with heavy equipment before the Gatewave could form properly again. The city acknowledged the disruption fell within an anticipated 12 to 18-month break-in process for the wave.

The Gatewave is controlled by three underwater gates that can be adjusted to account for the river's flow rate. The surf wave is designed for optimum conditions from about 450 to 1,200 cfs. The fall flood peaked at roughly five times that upper threshold, which explains both the volume of sediment moved and why the corrective earthwork required more than routine annual maintenance.

The city of Farmington worked collaboratively with the North Farmington Ditch Company to make improvements in the Animas River at Gateway Park. That partnership, which benefited both recreation users and the irrigation ditch that has run off the Animas for generations, also informs how the city approaches ongoing sediment management. Because the Animas is free-flowing with no upstream dams, when a flood event happens, sediment management work will be needed. The scale of what fell 2025 delivered, though, pushed well beyond what a standard winter cleanout could address.

The Animas River wave is flowing again after sediment and debris had rendered it unrideable, and video from the Gatewave showed people surfing again. The live webcam feed that stayed active throughout the entire shutdown now shows what it was built to show: a clean hydraulic, a steady rotation of surfers, and a wave profile that confirms the earthwork held. No other feature like it exists within easy driving distance of the Four Corners, and the Animas just got its best amenity back.
