Precipitation

[mychells]

How would a decrease in precipitation affect the supply of ground water in your region?

 

Thanks in advance!

This is a geology/meteorology question. Groundwater can persist in underground reservoirs for thousands of years, or the levels of water (the water table) can have a much closer dependence on rainfall patterns. It depends on the local conditions. So your question covers quite a bit of, er, ground.
