Geography of Lake Tahoe: Lake Tahoe is the second deepest lake in the U.S., with a maximum depth of 1,645 feet (501 m), trailing only Oregon's Crater Lake at 1,949 ft (594 m).[7] Tahoe is also the 16th deepest lake in the world, and the fifth deepest in average depth. It is about 22 mi (35 km) long and 12 mi (19 km) wide and has 72 mi (116 km) of shoreline and a surface area of 191 square miles (490 km2). Washoe Indians used the lake. Approximately two-thirds of the shoreline is in California. The south shore is dominated by the lake's largest city, South Lake Tahoe, California, which adjoins the town of Stateline, Nevada, while Tahoe City, California, is located on the lake's northwest shore. Although highways run within sight of the lake shore for much of Tahoe's perimeter, many important parts of the shoreline now lie within state parks or are protected by the United States Forest Service. The Lake Tahoe Watershed (USGS Huc 18100200) of 505 sq mi (1,310 km2) includes the land area that drains to the lake and the Lake Tahoe drainage divide traverses the same general area as the Tahoe Rim Trail.
