Farmington's Animas River Gatewave Returns, Welcoming Surfers Back to the Water

The Gatewave at Gateway Park on the Animas River was back in action Thursday, several months after a fall flood pushed river flows to nearly 6,500 cubic feet per second, buried the downstream gravel bar in sediment and killed the hydraulic jump that makes the wave rideable.

The surge, which struck in fall 2025, deposited heavy sediment just below the Obermeyer weir structure, raising the water level in the recovery pool and disrupting the hydraulics the feature depends on. The sandbar that channels the river's flow into the wave was also breached. City officials classified the disruption as foreseeable, noting the break-in period for a newly constructed riverbed structure was expected to run 12 to 18 months as the gravel and weir gates stabilize. Still, that projection offered little comfort to surfers watching the wave sit idle through winter.

The fix required contractors with heavy equipment to dredge accumulated sediment and rebuild the gravel bar once Animas River flows dropped low enough to allow safe access. The city's Parks, Recreation and Cultural Affairs department, which operates the Gatewave site, oversaw that work. A specific cost for the remediation has not been publicly disclosed, though the department has framed periodic sediment management as an ongoing operational reality for any engineered feature on an undammed river.

The broader project cost $2.6 million. The largest share, $2 million, came from the New Mexico Office of Natural Resources using funds designated from the 2015 Gold King Mine spill settlement specifically for river-recreation improvements. The city supplemented that with $500,000 from a State Trails Plus Grant and another $500,000 from its Community Transformation and Economic Diversification fund. Mayor Nate Duckett has publicly connected the Gold King settlement money to the project, positioning the wave as tangible redress for a disaster that contaminated the Animas a decade ago.

The feature uses three adjustable gates in the Obermeyer weir that city staff can raise or lower to shape the wave based on current flow conditions. The surf feature itself only forms when the Animas is running between 400 and 3,500 cfs; outside that window, the structure is present but the standing wave is not. The city posts live flow data and a camera feed on its Gatewave page so users can check conditions before making the drive to Gateway Park. The site remains unsupervised, with entry and exit via a natural rock staircase on the river's right bank.

Local surfers wasted little time returning. One rider described the sensation of surfing the feature as powerfully "ripping" and said the wave "fills me with pride." A commercial operator who works with river-wave equipment said it was gratifying to see the product performing as designed.

That commercial energy reflects what city planners had in mind when they assembled the $2.6 million funding package. Before the Gatewave opened, the nearest comparable surf wave was more than four hours away in central Colorado. A working feature in Farmington gives day-trippers and destination visitors a reason to stop on the Animas rather than drive north, and it creates a platform for local entrepreneurs building rental and lesson businesses around the wave.

City Manager Rob Mayes, who is set to retire June 30, oversaw the project through construction and launch. Whether the Gatewave becomes the consistent economic driver Farmington envisioned will hinge largely on how well the city manages the next significant flood season on the undammed Animas and whether the gravel bar holds.
