Critical information is totally absent from this article and all others I have read.  
**What is the long term evolution of groundwater resources?**  
The drought has exacerbated long term degradation of water resources.  
The drought is not the cause of the immediate emergency, the cause is the long term exhaustion of water resources as existential demand for water consumption has grown inexorably over the past century or so.  
When water is removed from an aquifer faster than it is replenished the exhaustion of that aquifer is a mathematical certainty. The larger the aquifer the longer the process will continue, and the greater will be the demand for existential consumption of the water extracted, but the end result is inevitable, and catastrophic.  
And the aquifers are in long term decline, and groundwater tables are dropping. The following are a few examples among many papers.
