The Great Salt Lake is the prominent body of water located within the Great Basin.

The Great Salt Lake, located in Utah, is the largest saltwater lake in the Western Hemisphere and a defining feature of the Great Basin. This lake has no outlet, causing water to evaporate and leaving behind high salinity levels. It is a key ecological site, providing essential habitat for migratory birds, particularly during the warmer months. The lake’s size and water levels fluctuate, largely influenced by regional precipitation and evaporation rates. As part of the Great Basin, it highlights the area's arid climate and unique hydrology.
