it happened before you were born and it will happen after you die.....who cares?Really surprising this has not aroused some international interest. All that water from Arizona has caused considerable expense and inconvenience in Mexico over the years. The natural watershed in Arizona is huge and dumps into the Sonoita. View Google Earth and you can see how huge the watershed is. The Sonoita River runs to the West along the border for quite a distance collecting run off from Arizona before it drops down to us .
I also had that thought the other day. Probably not cost effective due to the inconsistency of the flow.I'm surprised Mexico doesn't put a small dam by Naya it to replenish the aquifer for Penasco
