This is how dry it has been so far this season: California’s chances of having a normal “water year” have fallen to around 33 percent in much of the state, according to a federal scientist. Michael Dettinger, a hydrologist with the U.S. Geological Survey, said those dismal odds are based on the amount of rain and snow that has fallen so far this year – and the history of how much precipitation California traditionally gets in the remaining months of the rainy season.
