The low snowpack, higher temperatures, and increased rainfall in March are causing concern for Bay Area scientists and farmers. The March 1 Philips Station measurement found that snowpack measured 47% on average for March and 45% of the April 1 average, and statewide the snowpack stood at 66% of average. However, watershed scientists believe more rain and snowstorms in March will be crucial for preserving water resources across California. The snowpack is in better shape than it was one month ago, but there is only a month left of the snow-accumulation season left. Snowmelt from the Sierra Nevada accounts for approximately 30% of California's annual water supply, and agriculture uses approximately 40% of this state's total water use. Water storage experts are waiting until next month to determine the water year outlook.
