Running for nearly 1,900 miles, mostly through arid lands, the Rio Grande is one of the longest rivers in the U.S. It’s also one of the most managed, having been controlled by dams and other structures for most of the last century. Even in a good year, much of the river is diverted for irrigation. But it’s only May, and it’s already turning to sand. The farmers who work 62,000 acres along 140 miles of the #RioGrande may get by — or they may not. “Nobody’s got a whole lot of water,” said David Gensler, the hydrologist for the Middle Rio Grande Conservancy District, whose job is to manage the river water that is delivered through diversion dams, canals and ditches. “If we use it up early in the season and don’t get any rain further on, the whole thing’s going to crash.” Whatever happens this spring and summer, the long-term outlook for the river is clouded by #climatechange. The Rio Grande is a classic “feast or famine” river, with a dry year or 2 typically followed by a couple of wet years. If warming temperatures make wet years less wet and dry years even drier, year-to-year recovery will become more difficult.
