Lake Tahoe is the second deepest lake in the United States and 11th deepest in the world; at 6,225 feet of elevation it's the highest lake of its size in the U.S.; its depth is 1,645 feet, with an average depth of 1,000 feet; it has 72 miles of shoreline and a surface area of 191 square miles. These and other nuggets of Lake Tahoe lore and legend can be found at the Tahoe Center for Environmental Sciences and Lake Tahoe at Sierra Nevada College in Incline Village. The three-story, 45,000-square foot, environmentally-friendly energy-saving building, which was completed in early October, houses an educational and research center for all things Lake Tahoe. The Center is open daily to the public and there is no admission fee.
