Water Conservation in the West

Christian Science Monitor (opinion):
The seven thirsty states that drink from the Colorado River have learned a lot about conserving water, from desert landscaping to underground storage. But a credible new study shows that won’t be enough to solve the region’s water supply problem.
Tough choices lie ahead.
The study by the National Research Council used tree-ring differences to track the history of water flow in the river basin. It revealed that the years prior to a 1922 compact that set multistate sharing were exceptionally wet. That pact is still in effect.
Extended droughts, such as the one the region has been experiencing since 2000, have been common. The seven states – Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming – should be prepared for extended and possibly more severe droughts, according to the study. Right now, the basin’s two big reservoirs, Lake Mead and Lake Powell, are about half full.
