Lake Tahoe is a national treasure. It’s one of the world’s largest, deepest, and clearest mountain lakes—22 miles long, 11 miles wide and in a 501-square-mile watershed. The communities surrounding it depend on the protection of its stunning natural beauty and year-round recreational opportunities. The U.S. Forest Service and state agencies manage nearly 85% of the watershed’s land.
