This is different. For decades, the way to decide who gets how much water from the Colorado River involved big, protracted fights in Congress and the courts. Now, the Lower Basin states of Arizona, California and Nevada are voluntarily working on a drought contingency plan to cut the water each state gets from Lake Mead once a shortage is declared. California would agree for the first time to take cuts, which is definitely better than the current agreement that forces Arizona to take the bulk of the cuts while California escapes with none.
