Last year, researchers estimated that California had lost 238 trillion litres of water over the course of 18 months of drought. Now, a huge reservoir of underground water — three times bigger than engineers thought — has been found under California. But it still won’t solve the state’s drought troubles.
Do you remember where you were when you first realised the severity of the drought in the Western US? I would guess that you weren’t staring at a cloudless sky or a dry faucet. You were probably looking at a photo of Folsom Lake.
