California is suffering through five years of drought. Though our reservoirs aren’t full, the state Legislature has been flooded with proposals to deal with the drought’s impact and to address the Golden State’s future water needs. While the effects of the drought are highly visible — brown lawns, fallowed fields, declining river flows and low reservoirs — what you can’t see is the lack of easily accessible data that’s necessary to effectively manage the state’s water. California does not suffer from a lack of data on water.
