There is also the issue of carrying capacity of the land. Some years ago when I took a few trips to NM, AZ. NV, and CA I was amazed at the seemingly uncontrolled growth in such arid conditions, and so often with man made lakes in subdivisions, and generally profligate uses of water wherever I went. The current drought may change some of that but the damage has already been done. What the priority uses are however is a choice. They can choose to give 1st priority to productive uses of the land such as dreamerhps.
