Not sure why you've been downvoted. For years Central Valley aquifers have been getting drained faster than they refill, it's unsustainable. Particularly in the case of 'fossil aquifers', named because the water in them is ancient and doesn't appreciably replenish on human timescales. Central Valley agriculture isn't sustainable. The lower their ground waters get, the more they'll try to pull from the rest of the increasingly dry state. Californian politicians have no answer for this because there is none (other than 'scale back or move out') and they probably know it.
