Sean de Guzman from the Department of Water Resources confirmed this as the greatest April reading since automated sensors were deployed. The snowpack’s water content is a crucial indicator of the state’s future water supply.
Historical Comparisons
The snowpack in 1952, 1969, and 1983 also saw high levels, but the 2024 measurements surpass them due to more comprehensive sensor data.

De Guzman noted the 1952 measurement was also 237% of average, but fewer snow courses were measured then. This makes precise comparisons across decades challenging.
Challenges of Manual Measurements
Manual snow measurements continue despite weather and avalanche threats. The Department of Water Resources collaborates with the National Park Service and the U.S. Forest Service for comprehensive data.

These partnerships are vital for accurate water forecasting and managing the state’s resources effectively.
From Drought to Surplus
California faced severe drought conditions for three years until powerful storms began in December 2023.

These storms replenished reservoirs and built the extraordinary snowpack now seen in 2024. The rapid shift from drought to surplus showcases the variability of California’s climate.
Reservoir Storage Levels
As of May 2024, reservoir storage statewide is at 107% of average. This remarkable recovery from drought highlights the impact of the recent weather events.

Reservoirs that were once dwindling are now filled, ensuring a more stable water supply for the upcoming months.
Flooding Concerns
With the snowpack melting, significant flooding is expected, especially in the Tulare Lake Basin.

Karla Nemeth, director of the Department of Water Resources, emphasized the risk of “significant flooding.” The region, once a vast body of water, has already begun to reemerge due to the runoff.
Tulare Lake’s Historical Significance
Tulare Lake was drained in the 19th century for farmland. The current runoff is reviving this historic lake, posing both opportunities and challenges for the region.
