Take the Ogalalla acquifer for example, overall it is being depleted but measurements in the NW area show water level increases, possibly due recharge efforts as well as local precipitation.

Over time, this gives all the information we need to know whether we are unsustainably drawing down our groundwater. Thank you for your thoughts.

It is. We don’t. And outside of California it is well understood that this means it is simply impossible to have a truly sustainable water system. It’s like having a bank account without knowing who is taking money out or how much they are taking.... But it's this true world wide as we do not possess the technology to with reasonable accuracy measure the current quantity of water, where it is currently located, the reasonable probability of where it will migrate, over what period of time, as well as a host of other factors, making speculating on how much water is available at best a WAG (wild ass guess)...
