California has had one weird winter this year: lots of snow and rain early, and almost none since January. It’s in years like this that it’s especially crucial to know just how much water to expect from melting Sierra snows — runoff that provides about a third of the state’s water supply. Current estimates combine patchy measurements with a kind of sophisticated guesswork. But that may be about to change with new technology that’s currently being tested.
