All the diminished flow of the Colorado River water that entered Mexico in 2005 was used for urban and especially agricultural use. No water was proscribed to sustain the natural environment or wildlife. Working with the Mexican environmental group Pronatura, Yaqui Native Juan Butron led us on a sunrise canoe tour of the marsh La Cienega de Santa Clara that he helped restore. We saw nature and wildlife struggling to reinhabit the former wasteland. All the water that created this marsh came from agricultural runoff.
