Despite Late Winter storms
Following one of the driest Februaries in California history, late winter storms increased the Sierra Nevada snowpack but were not enough to put the state on track for an average year.
As of April 2, 2018 the snow survey by the California Cooperative Snow Surveys Program indicates that water content in the statewide mountain snowpack increased from 23 percent of the March 1 average to 52 percent of today’s historical average. This figure does not include last weekend's storms. The early-April snow survey is the most important for water supply forecasting because the snowpack is normally at its peak before it begins to melt with rising spring temperatures.
“These snowpack results – while better than they were a few weeks ago – still underscore the need for widespread careful and wise use of our water supplies,” said California Department of Water Resources Director Karla Nemeth. “The only thing predictable about California’s climate is that it’s unpredictable. We need to make our water system more resilient so we’re prepared for the extreme fluctuations in our water system, especially in the face of climate change.”
The snowpack normally provides about a third of the water for California’s farms and communities as it melts in the spring and summer and fills reservoirs and rivers.
