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.

    See my other comment below. Farms are not at zero.

  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. [1] Suffice to say the CVP supplies a significant portion of California's water. It is the largest such project in the country.

      From your Wikipedia link: > Water use in California is divided into approximately 51% for environmental uses, 39% agricultural use and 11% urban uses, though that varies considerably between regions and between wet and dry years. Solely relying on these statewide volumes is controversial because they don't consider the fact that most of the volume of water used for environmental purposes includes flows down Wild and Scenic Rivers in the North Coast where there is no practical way to recover it for either agricultural or urban use because it lacks many connections to the statewide water supply system. It also doesn't factor in the amount of water required to keep salty water from the Pacific Ocean from intruding into the Delta beyond a certain small concentration. If we set aside the 51% of California's water that isn't actually used by people, that 39% of total water becomes 79.6% of water used. So, yeah, 80% of usage.
