Mexico and U.S. Begin Dam Releases to Restore Colorado River (Op-Ed) Since 1960, the Colorado river has not flowed regularly to the sea. While pockets of green remain, the Colorado delta is a parched and begging for relief. The dry, sandy channel glares in the bright sun, abandoned by the river that has been overtapped and overworked for too long. Its hard not to think of the lost potential of an ecosystem that once thrived. After an adventure there in 1922, American author, scientist and environmentalist Aldo Leopold wrote: On the map, the delta was bisected by the river, but in fact the river was nowhere and everywhere, for he could not decide which of a hundred green lagoons offered the most pleasant and least speedy path to the Gulf [of California]. The Colorados delta was once a landscape of plenty, the basis of rural economic activity and local employment. Tourism, recreational hunting, sport and commercial fishing — all have been lost to overuse and over-exhaustion of a limited resource.

I spent much of the past 15 years shining a spotlight on the sorry state of the Colorado river delta for audiences across the country. And while its true that those conversations would quickly turn to the byzantine complexities of water law and the difficulties of caring for shared cross-border resources, it is also true that most people are truly unsettled by the reality that the Colorado stops short of its natural destination. Today, U.S. and Mexican policymakers, water agencies and conservation organizations are taking a major step to right the wrong that has been done to the Colorado river delta. For the first time in history, the United States and Mexico will send a modest volume of water into the Colorado River delta in the form of a temporary pulse flow, which will mimic the natural spring floods that once nourished the delta. Never before have we deliberately sent water below Morelos Dam — the last dam on the river just south of the U.S.-Mexico border — to benefit the environment. Beginning this month, water from the Colorado river will literally pulse through the border as a sign to the rest of the world of what people can accomplish through cooperation between nations. It feels like a triumph of human optimism over acquiescence.
