New research explores how farmers can help California rebuild its groundwater supply

During drought years, California relies heavily on its groundwater supply. As droughts become longer and more intense with climate change, it's becoming more important than ever to "bank" excess surface water during stormy weather patterns in order to provide some long-term insurance. That's the goal of the Sustainable Groundwater Management Act, which was passed in 2014. In order to meet that goal, state and local water managers need to work together to search for possible methods of recharging groundwater aquifers. And the sooner the better, because there is a lot of water missing from those basins.
