This suite of short films documents the graceful optics of four anthropogenic wetlands in the Colorado River Delta. These Mexican sites get their water from transnational agricultural canals and need binational diplomacy to keep them alive. The imperiled Andrade Mesa wetlands once profited from leaks in the nearby All-American Canal, but the repair of this canal has left the wetlands without a water source. The shimmering Ciénega de Santa Clara sprung to life when an Arizona irrigation district began dumping drain water into a degraded stretch of Mexican delta—unintentionally creating a critical habitat. The verdant Las Arenitas site transforms Mexicaliís municipal effluent into a luxuriant wetland—its limitless water source ensuring its future. Sylvan Laguna Grande along the Colorado Riverís mainstem flourishes with the help of Mexican and U.S. environmental agencies. Irrigated with less than one percent of the riverís historical flow, Laguna Grande successfully leverages scarce borderland resources and binational collaboration.
