EcoWatch: The snowpack for the state of California--a critical source of drinking water for the state--hit its lowest level in the last 500 years, according to a study published yesterday in Nature. When the snowpack was measured in April--historically the high point for the season`s snowpack--it was just 6 percent of average for the past century.
