Drought deepens strain on a dwindling Colorado River

Salt Lake Tribune: The drought gripping Utah, Southern California and the rest of the Southwest this century shows no sign of ending. Scientists see it as a permanent condition that, despite year-to-year weather variations, will deepen as temperatures rise, snows dwindle, soils bake and fires burn. That's grim news for all of us in the West, perhaps most especially for the 10 million residents along the northern stretch of the Colorado River -- Utah, New Mexico, Wyoming and Colorado -- whose water rights are newer, and therefore junior, to those in Southern California, Nevada and Arizona.

Making matters worse, the Colorado -- the 1,450-mile-long lifeline that sustains more than 30 million souls and 3.5 million acres of farmland in seven states, 34 tribal nations and Mexico -- is in decline, scientists warn.

Even so, demand for the Colorado's water echoes from city leaders, industry giants, oil drillers, farmers, fishers, ranchers, boaters, bikers and hikers -- along with silent pleas from wildlife and the ecosystem. Trend analyses by federal scientists, probably conservative, predict the population dependent on the river will reach at least 38 million during the coming decade.

Right now, California, with the most senior rights and the largest share of the Colorado under a 1922 law, is struggling with a statewide water shortage. Not enough rain has fallen in the southland, as weathercasters like to call it, home to 18 million people, roughly half the state's population.

…Demand is up. Flows are down. Something has to give. And when it does, Utah could be in trouble if it doesn't change its wasteful ways -- just as 19th-century explorer Maj. John Wesley Powell predicted….
