Colorado River water policy faces an age of limits

Change comes hard to Western water policy. The Prior Appropriation Doctrine, interstate compacts, groundwater law, the "law of the river" -- all of these seem set in stone in the minds of the region's policymakers. Of course, the West's rivers aren't bound by such a static existence. Indeed, they are changing in fundamental ways, opening a wide chasm between our water policy and our water sources. This is particularly true for the Colorado River Basin. Climate scientists are predicting a 10-to-30 percent reduction in flow for the Colorado -- a stark contrast to the rosy assumptions that underlay the Colorado River Compact when it was signed 88 years ago. It is time for a new era in water management. The first step requires dispensing with the absurd notion that infinite growth can take place in a region with severely constrained resources. The second step is to realize that agriculture, which uses the lion's share of the river, is going to take a big hit. Many of the crops grown in the basin are low value, such as hay, or are commodity crops that are already over-produced in the United States. And the third step requires improving the quality of the water by forcing all polluters to clean up their mess. That includes agriculture, mining and municipalities with inadequate urban treatment. These changes will not be easy -- it's like prescribing a root canal for an entire region without offering nitrous oxide. But the longer we wait, the more difficult it will be to make the transition to a policy that meets the reasonable needs of cities, a service economy and the age of limits...more
