Overview
- Statewide snowpack measured about 66% of average Friday ahead of the month's third manual survey at Phillips Station, according to state figures.
- Recent warm rain percolated into colder snow and refroze, lifting the median snow water equivalent from 70% to 75% this week, researchers said.
- The State Water Project projects supplying roughly 30% of requested deliveries, while the Central Valley Project set initial allocations of 15% for major agencies south of the Delta and 100% for many north of or within the Delta.
- Conditions vary sharply by region, with the Southern Sierra near 90% of average, the Central Sierra near 67%, and the Northern Sierra about 46%.
- Reservoir storage remains strong—Shasta at about 115% of average and Oroville near 129%—but a relatively dry short‑term forecast and the shrinking window before the April 1 peak limit prospects for a major rebound.
