This might just be me, but I prioritize agriculture over swimming pools. It's strange that it is agriculture to blame when LA doesn't source its own water and instead diverts water from the central valleys away from agriculture. Agriculture doesn't "pay their fair share", yet LA is actively taking water away from agriculture and also draining 5-7 year reservoirs. When wild fires are in full swing we're going to really regret not having those reservoirs. [0] Most farms have had their water share cut to zero already. [1] People would rather waste water on LA lawns and swimming pools (or dump it in the Pacific, which is what happens to most of it that reaches LA [2]) rather than produce food with it. This is just baffling to me. [0]: https://californiaglobe.com/articles/ca-reservoirs-filled-to-top-in-2019-being-drained-by-state/ https://californiaglobe.com/articles/ca-reservoirs-filled-to...

The point is that if you add up ALL the swimming pools in California, it totals ~0 water. Not even a rounding error. Farmers measure water use in MILLIONS of ACRE FEET. There is even an acronym for it: MAF. There are rice paddies surrounding the capital city of Sacramento. Why do we keep asking residents to sacrifice for even trivial pleasurers like swimming, when it makes no difference at all?

  No political will to force ag and industrial water users to curtail usage to sustainable (less than aquifer replenishment rate) levels.

    Yes, but the article doesn't share any numbers that give a sense as to how much water that actually is. How much water does the Central Valley Project normally deliver? What fraction of total water use is that? What fraction of ag water use is it? My hunch is that this is a small fraction of the amount of water farms use. There are a lot of articles like this that make it sound like farms are really hit hard and having to endure sacrifices. There was one from a few months back talking about farmers that had to destroy a bunch of almond trees they couldn't afford to water anymore. About 400 acres worth. There was a dramatic photo of a farmer standing next to a bunch of uprooted trees. Reality: there are 1.6 million acres of almonds in California. Pulling up 400 acres is nothing.

      We don't need to rely on hunches. > In an average year, about 39% of California's water consumption, or 34.1 million acre-feet (42.1 km3), is used for agricultural purposes. Of that total, 11%, or 8.9 million acre-feet (11.0 km3) is not consumed by the farms for crop production but is instead recycled and reused by other water users, including environmental use, urban use, and agricultural use, yielding net water consumption for food and fiber production equal to 28% of California's water consumption, or 25.2 million acre-feet (31.1 km3). [0] The 80% figure is false. > In a normal year the CVP delivers about 7 million acre-feet of water for agricultural, urban, and wildlife use.

    Probably they are considering the data for California (relevant to this discussion) rather than the US as a whole. Although the link you posted doesn't break out the percentage for California, it does say that 20% of western state alfalfa is exported. However, the percentage is less important than the overall amount. "If California only produced enough almonds for the United States, than it would have about 8 percent more available water. If California only produced enough alfalfa for the U.S., it would have at least 3 percent more available water." https://www.sandiegouniontribune.com/opinion/commentary/story/2021-08-13/california-drought-water-agriculture-almonds-alfalfa-water-intensive https://www.sandiegouniontribune.com/opinion/commentary/stor...
