Is the only remaining use left agricultural?
Looks like on average the data shows 42% agricultural. https://water.ca.gov/Programs/California-Water-Plan/Water-Po...
No, you are being misled by “environmental water,” which is a fancy way to say it’s water we don’t use because were not allowed to. This doesn’t make any sense, how can you include water you don’t use in your accounting for water use?
The reason this is there is to downplay the outsized use in agriculture, and also to shift some blame to folks that voted not to allow this water to be used in the first place.
But still, if you want to cut spending and are looking for where your money is spent, you don’t include money you choose not to earn in your list of spending.
In California, where we have persistent water shortages, residential, commercial and industrial water use ( including all landscaping, golf courses, etc) all put together still only amount to 10-20% of overall water use, depending on rainfall
