The Sierra Nevada is getting soaked this year, and Lake Tahoe is one of the biggest beneficiaries.

The sixth-largest lake in the United States, which straddles California and Nevada, reached its natural rim after weekend storms dumped 12.5 billion gallons of water into the lake. A trickle is now flowing through the dam and into the Truckee River. This is a huge milestone for a body of water that has flirted with record-low levels amid an ongoing drought.
