The immediate question before the seven states that use rapidly vanishing Colorado River water is not how to renegotiate the century-old agreement and accompanying laws that divvy up the supply. California and other states will have to grapple with that problem soon enough, and it won’t be easy. Those accords were hammered out in an era when the Western U.S. was lightly populated, farmland was not yet fully developed and the climate — although few realized it at the time — was unusually wet. Now, when the thirst is greatest and still growing, the region is reverting to its former aridity, exacerbated by higher temperatures caused by global industrialization. But the deadline for that reckoning is still nearly four years off.
