The new year begins with a minimal snowpack in the Sierra Nevada as measuring stations across the state report an average Wednesday of 2.3 inches — just 21 percent of normal. “The survey is a disappointing start of the year, but it’s far too early to draw conclusions about what kind of a wet season we’ll have this year,” said Frank Gehrke, chief of the California Cooperative Snow Surveys Program. “There’s plenty of time left in the traditional wet season to reverse the dry trend we’ve been experiencing.”
