Early snowmelt complicates California's water storage
California faces a challenging water management scenario as record-breaking heat triggers early snowmelt in the Sierra Nevada, reducing the snowpack to just 38% of its mid-March average. While reservoir levels are currently above historical averages, the premature runoff complicates efforts to effectively store water for the drier months ahead. The Yuba Water Agency is grappling with flood-control mandates and a significant pipe rupture, hindering their ability to maximize snowmelt storage.
