March storms are building the Sierra Nevada snowpack and helping to fill key reservoirs that are tapped in the spring and summer for water supply. The recent series of storms brought more snow to the Sierra Nevada – mostly in the northern Sierra.

Maury Roos, a hydrologist with the California Department of Water Resources, says the northern Sierra has nearly received its average precipitation for the entire month of March. But, Roos says, it’s not “Miracle March”… yet.
