Geographic Setting

Lake Tahoe is the largest subalpine lake in North America. At 22 miles long and 12 miles wide, it is a beautiful expanse of deep, blue water. What makes it so intensely blue? Its depth. At its deepest point Lake Tahoe plunges to 1645 feet with an average depth of approximately 900 feet. With its huge surface area, that’s a lot of water. Tahoe is blue also because it is so clear and clean. Its clarity is primarily because the basin around it is fairly small and the water is very cold and the soils and vegetation have prevented nutrients from entering the lake where they would increase algae growth.

Since the 1960s and 1970s there has been dramatic population growth and increased development in the Tahoe area, which has had a negative effect on the lake. An increase in algae growth has reduced Tahoe’s legendary clarity. A substantial investment of energy and money is now underway to protect the lake.
