But the most important factor is ground water and if this is getting depleted.....we're in trouble !!!
Here in the western U.S. such reservoirs are measured by acre feet. The surface area of the reservoir is known and when it drops by one foot (or multiples) then the amount of acre feet consumed are known. The hydrologists can determine the total voulme of the usable reservoir and predict how much will be remaining after a given period of time...
