California's Extreme Percipitation this Winter Will Not Solve Water Problems

Oroville Dam, California

Amazing rain and snow in California this winter have made people think the drought is finished and everything can go back to normal.
California gets it water from three sources, about a third each from: precipitation, snowpack, and aquifers (groundwater). In many areas of the state, groundwater systems have been depleted for long periods - even between droughts - from which they have not recovered.
Excessive, long-term groundwater over-use resulting in groundwater depletion can cause subsidence and permanent loss of groundwater storage as well as water quality degradation and seawater intrusion. These long-term impacts on groundwater have not been remedied by the recent weather. If recovery is possible, it will likely take several to many years to accomplish.
