While wasting water isn't smart, so much of the water flowing through Lake Mead is used for agriculture in deserts where it doesn't really belong that worrying about flow from California/Arizona residents' shower heads is focusing on the wrong problem.
Problem is, those farmers have a LOT of political pull, and the way the water allotments were set up makes it really hard to change them despite population in the region increasing by over an order of magnitude since they were drawn up.
Biting the hand that feeds IT
