The Fort Yuma-Quechan Indian Tribe is situated at a nexus in the Colorado River Basin. That’s true in a geographic sense. The tribe’s reservation overlays the Arizona-California border near Yuma, Arizona. The two states are heavily reliant on water from the Colorado River. The reservation also abuts the U.S.-Mexico border where the river flows into Mexico for use in cities and on farms. One of the river’s largest irrigation projects, the All-American Canal, was dug through the tribe’s land, and flows from the reservation’s northeastern boundary to its far southwestern corner, on its way to irrigate crops in California’s Imperial Valley.
