They are the same use, but it seems on the agriculture side there is little incentive to use water efficiently based on rights that were granted 100 or more years ago. Off and on I’ve been trying to find a video I saw on YouTube several years ago where an ag-ed group had found (and I’m going to get this way wrong) growing lichens along with crops trapped a lot of moisture near crop root systems providing a significant reduction in irrigation requirements. But if water is cheap, why would a farming operation introduce risk or complicate their operation. I’d personally like to see AZ get some of its water rights to the Colorado river back. Our state government is talking about building and operating desalination plants in Mexico to meet future while CA sits on hundreds of miles of coast, takes about 60% of allocated CO river water, and already operates a desalination plant. For the ongoing cost of a plant and operations, no one is willing to give up an equivalent portion of existing water rights?
