California prepares for abundant spring water supply from snowmelt.

California's Department of Water Resources has forecasted that spring runoff will be well above average for watersheds throughout the state due to one of the biggest snow seasons on record for the Sierra. The runoff is expected to fill reservoirs and downstream waterways, with releases being made to manage capacity. Water managers are anticipating high flows on rivers throughout the San Joaquin region for the next several months and are carefully monitoring flood risks for communities along the Tuolumne, San Joaquin, and Merced rivers. The Tulare Basin is forecast to see runoff in excess of 400% of the average, and snowmelt will also impact Lake Tahoe.
