Overview

  • California's Sierra Nevada snowpack has reached 96% of its historical average as of April 1, 2025, following significant late-season storms.
  • This marks the third consecutive year of average or above-average snowpack levels, a rare occurrence last seen from 1998 to 2000.
  • Reservoirs statewide are at 117% of their historical average capacity, ensuring robust water reserves for the dry season.
  • Regional disparities persist, with the Northern Sierra snowpack at 118% of average, while the Southern Sierra lags at 84%.
  • Warmer temperatures in the coming weeks could accelerate snowmelt, raising concerns about wildfire risks and water management challenges.
