description Great Salt Lake Overview
The Great Salt Lake is a vast, endorheic saltwater lake located in northern Utah in the United States. It is the largest saltwater lake in the Western Hemisphere and a modern remnant of the massive prehistoric Lake Bonneville. Because it lacks an outlet, the lake's salinity levels far exceed that of the ocean, creating an environment where only extremophile organisms, such as halophilic archaea and brine shrimp, can survive. It is currently experiencing significant water level declines due to drought and water diversion.
help Great Salt Lake FAQ
Why is the Great Salt Lake so salty?
The Great Salt Lake is an endorheic lake, meaning it has no natural outlet to the ocean, so water leaves only through evaporation. This continuous process leaves dissolved minerals and salts behind, resulting in salinity levels that can exceed 27% in some areas.
Where is the Great Salt Lake located?
The lake is located in northern Utah in the United States, bordering the state's capital city of Salt Lake City. It is a modern remnant of the massive prehistoric Lake Bonneville, which once covered much of the region.
Are there fish in the Great Salt Lake?
Because of the high salinity, the Great Salt Lake does not support populations of fish. However, it is famous for its massive populations of brine shrimp and brine flies, which provide crucial food sources for millions of migratory birds.
Can you float in the Great Salt Lake?
Yes, the extremely high salt concentration makes the water exceptionally dense, allowing swimmers to float effortlessly on the surface. Visitors often go to Antelope Island State Park to access beaches and experience this unique buoyancy.
