What will happen if Great Salt Lake dries up?

As the lakebed becomes exposed, toxic dust mixed with metals and metalloids like antimony, copper, zirconium and arsenic become a problem, per Live Science. The dust could lead to soil degradation and snow melt, as well as raise residents' risk of respiratory conditions, heart disease, lung disease and cancers.

The precipitous drop in water levels, which has shrunk the Great Salt Lake's footprint by half in the last decades, stems from a two-fold problem: Climate change has decimated the mountain streams that feed the lake, while demand for that same freshwater has ballooned for new development, agriculture and industry.

Lake Levels Due to its shallowness (an average of 14 feet deep and a maximum of 35 feet deep), the water level can fall dramatically during dry years and rise during wet years. When snowpack melts in the spring, the lake usually rises about 2 feet. However, record snowpack in 2023 triggered a rise of 5.5 feet!

The 1,700 square miles of various water environments, remote islands and shorelines, with Utah's highest density of wetlands, provide habitat for plants, brine shrimp, reptiles, amphibians, mammals, shorebirds and waterfowl. Birds rely on the lake, a critical link in the Pacific Flyway between North and South America.

After the ice age the earth's climate became drier and Lake Bonneville gradually receded to form Great Salt Lake. Great Salt Lake is too saline to support fish and most other aquatic species. Several types of algae live in the lake. Brine shrimp and brine flies can tolerate the high salt content and feed on the algae.

A new scientific report warns the lake is on track to disappear in the next five years, unless water use is cut by as much as 50% annually. I don't know of any other environmental threat that's moving this quickly, said Bonnie Baxter, a Westminster College biochemist and one of the authors of that study.

A recent report found that the lake could essentially disappear within five years. As a key stopover for migrating birds, the lake's loss could undermine whole ecosystems. These salty lakes occur in so-called endorheic basins—places where there is no outlet for the water to flow out to sea.
