The Great Salt Lake Basin is one of the major basins in the Great Basin region, and it is known for the large, saline lake that dominates the area.

The Great Salt Lake Basin is a significant part of the Great Basin and is centered around the Great Salt Lake in Utah. Unlike the Rio Grande or Columbia basins, which are associated with distinct river systems flowing into larger bodies of water, the Great Salt Lake Basin is an endorheic basin, meaning that water within it does not flow out to any ocean. This area is famous for its unusual environment, which includes marshes and salt flats, and for having a distinctive saltwater lake. While the Rio Grande Basin is a component of the broader watershed that drains into the Gulf of Mexico, the Snake River Basin and Columbia Basin are situated in separate locations.
