Another federal deadline passed Monday for seven states in the U.S. West to wrap up work on a plan to ensure the drought-stricken Colorado River can deliver water to the 40 million people and farms that depend on it. The states — Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming — have been working for years on drought contingency plans. But Arizona and California have missed two deadlines set by the U.S. Bureau of Reclamation and still have work to do.
