Which large salt lake in Utah is the largest in the Western Hemisphere?

The story behind the answer

Which large salt lake in Utah is the largest in the Western Hemisphere? Great Salt Lake is the correct answer.

Great Salt Lake is a hypersaline, landlocked lake in northern Utah. It is the largest saltwater lake in the Western Hemisphere and one of the world’s largest terminal lakes, meaning that rivers flow into it but no river carries water away to the ocean.

Its main inflows include the Bear, Weber, and Jordan rivers. As water evaporates, dissolved minerals remain behind, making the lake much saltier than seawater. Salinity varies substantially by location and by water level, especially because a railroad causeway divides the lake into northern and southern sections.

The lake supports brine shrimp, brine flies, and large numbers of migratory birds, but it cannot support most fish. Lake area and depth change dramatically with precipitation, drought, and river inflow, so “largest” refers to its status as a saltwater lake rather than a fixed modern surface area.
