Water experts say it's going to take more than one big year to fill the Great Salt Lake. SALT LAKE CITY — Ever since The Great Salt Lake hit its lowest water level on record in November 2022, concerns over things like arsenic in the exposed lake bed have only grown.
So just how bad is it, really? 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.
To augment the declining Great Salt Lake , a pipeline has been proposed to pump seawater from the Pacific Ocean. As extreme as it sounds, the idea is still being considered almost a year after it was first raised.
However, the most deleterious effect of the Great Salt Lake drying up is that the air surrounding Salt Lake City could sporadically become poisonous. Since the bed of the Great Salt Lake holds high levels of dangerous particles like arsenic, antimony, copper, zirconium, and various heavy metals.
Within years, the lake's ecosystems could collapse and millions will be exposed to toxic dust contained within the drying lakebed, unless drastic steps are taken to cut water use. A team of 32 scientists and conservationists caution that the lake could decline beyond recognition in just five years.
SALT LAKE CITY (ABC4) — The Utah Division of Water Resources is sharing good news about the impacts all the rain is having on the Great Salt Lake, whose water levels reached a historic low last year.
Most recent data within water-surface elevations show a downward trend. With climate change and Utah's ever growing human population, we expect this negative trend to continue. In fact, it is estimated that the lake is 11 feet lower due to human diversions.
The shallow bottom of Great Salt Lake supports a microbial carpet that harness the sun's energy through the process of photosynthesis. This carpet is made up of a community of microbes, including several types of cyanobacteria (also known as blue-green algae), algae and other organisms.
The state of Utah owns basically most of the Great Salt Lake, including Antelope Island, Fremont Island, Gunnison Island, the Ogden and Farmington bay wetland areas, along with the entire lakebed.
Lake LevelsDue 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 precipitous drop in water levels, which has shrunk the Great Salt Lake's footprint by half over the past few decades, stems from a two-fold problem: Climate change has helped decimate the mountain streams that feed the lake, while demand for the streams' fresh water has ballooned for new development, agriculture ...
“Impressive winter precipitation and record-breaking snowpack have undoubtedly improved the situation of Great Salt Lake,” Hasenyager said. “However, it's important to note that it will take much more than one above-average winter to fully replenish the lake's water levels and address our long-term challenges.”
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.
Compass Minerals announced in 2021 it was seeking to extract lithium from the Great Salt Lake under a pilot program. The company, which has a plant in Ogden, said it was utilizing new methods of extracting the precious resource within the ambient brine of the Great Salt Lake.
Because of the abundant algae and halophiles, as well as the high salinity, the lake does not support fish — but it teems with brine shrimp and brine flies, which provide essential nutrition for migrating birds.
Bacteria can decompose quickly, but it removes oxygen at a more rapid pace. This can also be a source of the rotten egg smell that the Great Salt Lake is known for.
