California’s historic drought has forced the state to rely on underground water reserves to an extent unseen in decades. One of the biggest water issues facing the state is how to maintain and rebuild its groundwater supply.

 

“After four years of drought, farmers are looking to gather up more water than ever,” said Jay R. Lund, director of the Center for Watershed Sciences at UC Davis. “People are going to be trying to refill aquifers with increased motivation due to the fourth year of drought.”
