More water woes

This time it's a dispute between two American states:

The issue before the court centered on a claim that Wyoming has been consuming more water due to irrigation advances such as center-pivot sprinklers.

Those sprinklers allow farmers to use water more efficiently, by increasing the amount that goes directly to their crops. But they also mean less surplus water comes off of fields - decreasing the "return flow" into rivers that flow downstream to Montana.

From the Bismarck Tribune. So in other words, Montana is mad because Wyoming isn't wasting enough water. Does that make any sense?
