Alarcón Gómez, a civil engineer who joined the restoration effort in 2016, treats the revival of this ecosystem with the same precision she once applied to urban infrastructure. Eleven years ago, this patch of the delta was a wasteland of salt-crusted earth dominated by invasive shrubs. Today, the canopy is dense enough to shield bobcats and coyotes from the sun, and the return of beavers marks a profound shift in the local hydrology.
The work is a labor of careful geometry and timing. Her team designs restoration plots that mimic the river’s natural meanders, using controlled flooding to push life back into the soil. In a region where every liter of water is contested, Alarcón Gómez must act as a steward of scarcity, directing environmental flows to the most vulnerable corridors of the Pacific Flyway.
The survival of El Chaussé rests on international diplomacy as much as engineering. Binational water treaties, specifically Minute 319 and Minute 323, provided the legal framework for "pulse flows"—artificial floods that jumpstarted the germination of native seeds. Alarcón Gómez manages the resulting growth by monitoring flora behavior and maintaining irrigation systems that rely on the same canal network used by local farmers.
The restoration technique mimics the natural river-meander behavior, working in harmony with nature to allocate extremely scarce water.
This forest is not a wild accident but a deliberate act of reconciliation. By securing water rights and clearing the thirsty, invasive flora that can consume 750 liters of water daily, the project has proven that the end of a river does not have to be a desert. As the seeds continue to fall like snow across the Valle de Mexicali, they carry the quiet weight of a landscape being pieced back together by hand.
