Water levels supporting much of midwest[1] farming and ranching have been dropping for decades, far faster than the refill rate. Even areas that have formed water-use co-operatives have been unable to convince themselves to reduce draw enough to matter. Even if they zeroed their usage, the co-ops don't cover enough land area to make up for the surrounding areas that are drawing from the same aquifer.
