Dust from the Great Salt Lake has already been recorded in southern Utah and Wyoming, according to the report.

The lake bed contains toxic dust mixed with dangerous metals and metalloids such as antimony, copper, zirconium and arsenic that could be kicked up and carried by gusts of wind to damage crops degrade soil melt snow and, if inhaled, increase the risks for illnesses such as asthma, bronchitis, heart disease and cancer.

If the lake is to be saved, overall water usage must be rapidly cut by 30 to 50%.Ī receded shoreline of the Great Salt Lake just outside Salt Lake City. Scientists and conservationists pin the blame squarely on excessive water use by the region's alfalfa and hay farms, which take 74% of the many trillions of gallons of the total diverted lakewater to irrigate their vast operations, according to the report. The Great Salt Lake provides a habitat for around 10 million migratory birds and brings Utah roughly $2.5 billion a year in economic activity, but, after drying at record rates since 2020, is currently sitting at 19 feet (5.8 meters) below its natural average levels, the report found. 4 report by a team of 32 ecologists and conservationists, says that the lake has lost 73% of its water and 60% of its surface area since 1850 and is facing 'unprecedented danger.' Without emergency measures to add an additional 326 billion gallons (1,234 billion liters) of water to the lake per year, or enough water to fill nearly 500,000 Olympic-size swimming pools, it could pass the point of no return by the end of 2024.
