The Sierra snowpack may be next to nothing, but the Stockton area is set to receive another full supply of water from New Melones Lake, and there’s no reason to expect a shortage here this year, officials said. While the lack of snow is a big concern for the state as a whole, most reservoirs still are in healthy shape for the moment thanks to last winter’s floods. New Melones probably is in the best condition of the major reservoirs, at 134 percent of normal.
