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.Without a consensus among the states, the agency will allow governors from the seven states to weigh in with recommendations on what to do next. The federal government also could step in and impose its own rules in the river's lower basin, affecting California, Arizona and Nevada.
