More than 6 billion gallons of water have poured into Lake Tahoe in less than two days, helping the lake begin to recover from four years of crushing drought.

Since midnight Monday, the lake has gone up 1.92 inches, the equivalent of 6.39 billion gallons of water, according to the National Weather Service. The water comes as a winter storm slams the Sierra, bringing several feet of snow to higher elevations and rain at lake level, which sits at roughly 6,223 feet.

The lake—the second deepest in the United States behind Oregon's Crater Lake—was hit hard this year by the drought. Over the summer, the lake was shockingly low. Many boaters were unable to get their crafts into the lake after waters pulled back from most boat launches.
