Environmental context
The Yuma Desert Dunes WRF discharges into the Colorado River basin, a critical waterway in the arid Southwest. The Colorado River flows through the Sonoran Desert, supporting irrigated agriculture, riparian habitats, and species such as the southwestern willow flycatcher. Downstream, the river reaches the Gulf of California in Mexico, where freshwater inflows are essential for estuarine ecosystems. Protecting water quality in this basin is vital for both human and ecological communities in a region facing water scarcity.
