Thanks to overuse of water and drought, the lake has shrunk to a record low level, revealing lakebed sediments contaminated with toxic materials.
This simulated 3D view of the Great Salt Lake is based on satellite data collected on July 9, 2022. Much of the lighter colored land around the lake once was covered with water. See below for a virtual flyover of the lake. The Great Salt Lake is not nearly as great as it once was.that it had reached its lowest level in 175 years of record keeping.
As farmers, industry and the fast-growing cities of the Wasatch Front, including Salt Lake City, have diverted more and more water from the rivers coursing down from the mountains, the balance has been upset. Apublished in 2017 showed that consumptive use of water had lowered the lake by 11 feet and reduced its volume by 48 percent.
So does this photograph, taken on July 9 from the south shore of the lake at Great Salt Lake State Park: The Great Salt Air resort, circa 1900. This structure burned down in 1925. The current building on the site, built in 1981 — and flooded by the lake a few years later — was once at the edge of the water.

“This is a disaster,” says Kevin Perry of the University of Utah, lead researcher on the survey, quoted in a. “And the consequences for the ecosystem are absolutely, insanely bad.” And even without further declines in the lake's level, hot spots would increase as people ventured out onto the already exposed lakebed, further disturbing the surface crusts. Ultimately, the researchers found that these disturbances, plus reductions in plant cover protecting the crusts, could make more than a fifth of the lakebed vulnerable to producing dust plumes.
In their report, Kevin Perry and his colleagues note that despite Kennecott's efforts at dust suppression, high winds commonly kick up big plumes from the tailings pile. Under high winds on July 9, 2022, dust swirls up from embankments of a giant mining waste impoundment on the south shore of the Great Salt Lake. The waste, or tailings, comes from a nearby Kennecott copper mining operation. The stack in the distance is part of the ore smelting facility. It's almost as tall as the Empire State Building.
