Mexico seeks to restore Colorado River’s flow
More than a century ago, the [Colorado] river’s delta spread across 1.9 million acres of wetlands and forests. The conservationist Aldo Leopold, who canoed through the delta in 1922, described it as “a hundred green lagoons” and said he paddled through waters “of a deep emerald hue.” He described it as an oasis that teemed with fish, birds, beavers, deer and jaguars. In the years after his visit, the river was dammed and its waters were sent flowing in canals to farms and cities. For decades, so much water has been diverted that the river seldom meets the sea. Much of the delta has shriveled to stretches of dry riverbed, with only small remnants of its wetlands surviving. Restauremos El Colorado manages one of three habitat restoration areas in the delta, where native trees that were planted six years ago have grown into a forest that drapes the wetland in shade. Last spring, a stream of water was released from a canal and flowed into the wetland, restoring a stretch of river where previously there had been miles of desert sand.
