The rain storms and blizzards that were supposed to come with El Niño were conspicuously non-biblical in California this winter, leaving the state in an ecological limbo that has regulators thinking about easing water-use restrictions in some places but not in others.

While the weather cheered ski resorts hit hard by the historic drought and brought some reservoirs to their highest points in years, in the end it dropped less snow than average in the Sierra, where more than a third of the state’s water comes from.
