I don't disagree, but aquifer filling is in part a function of precipitation over time. And when an area is getting much more precipitation over time than it used to, it increases the aquifer fill rate. There is also the "new" opportunity to build reservoirs on the rain sheds. If it had been impractical before it can become practical given even a modest increase in the average yearly rainfall. I good example of that is the LA project[1] to recover rain runoff rather than sluice it out to the ocean.
