California is beginning to identify places to store storm water after concerns that groundwater supplies are decreasing.

The California Department of Water Resources has recently announced its new groundwater mapping project that will “provide critical information” about the underground water supply, it said in a statement.

The mapping project will allow officials to decide where replenishment is needed.
