Buy land where it rains. Lake mead is going lower because a. Global warming or b. 10s of millions more people draw from it now compared to 1940.
80% of water leaving Lake Mead goes to agriculture primarily in California and Arizona people as in residential use less than 10% of the water. In California they take now with restrictions 4.4 million acre feet per year. Nevada gets 300,000 and Arizona gets 2.8 million. Both Arizona and especially California grow water hungry crops in the desert that have no business being grown there such as rice, almonds and especially alfalfa hay which uses FIVE FEET of water per square foot per year to grow. It is singly the largest user of water in California using five million acre feet per year in California alone. Each almond uses two gallons think about that each individual almond uses two gallons to grow to harvest. Clearly this is not sustainable. People who have no math skills and even less actual knowledge beat on Las Vegas they are the most efficient user of water in America in a acre foot to gross state product of economic activity. They use less than their smallest 300,000 acre feet per year while having 40+ million tourists per year. Casino’s use less than 1% of that 300k and generate 13+ billion in GSP. They also recycle back to Lake Mead every drop that hits a drain in that basin in a feat of hydrological engineering unequaled in North America only the Israelis have a higher percentage of water reuse. Fact is California needs to be cut off from Colorado river water going to agriculture or at least limited to a percentage not a raw amount well in excess of 4 million acre feet which they dump on crops that have no ecological reason to be grown in a desert. The break down of California gross water is 40% agricultural,10% industrial and residential and 50% environmental but that is rural from all California sources including local rainfall. If you just look at imported Colorado river water then it’s 80% big agriculture and 20% industrial/urban use for their 4.4 million acre feet. Big agriculture needs to do with less that’s just a fact.
Global cooling is a better answer.
Cooler sun, less condensation
