The largest of these, by far, is the Great Salt Lake in Utah. But a recent report found that water diversions for farming, climate change and population growth could mean the lake essentially disappears within five years.

Water Loss Is Due to Human ConsumptionThe team concluded that the source of Great Salt Lake's water loss was largely due to water consumption by humans dwelling in the surrounding areas. It wasn't about the water flow rate but the amount of water flowing into the lake.
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.
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.

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.
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!
Changes in climate over thousands of years reduced the depth of Lake Bonneville from nearly 1,000 feet to today's average of only 16 feet for the Great Salt Lake. The lake still contains nearly 4.6 cubic miles of water.
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.
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.
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.
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.
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.
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.
Recreation in, and around, the lakeThe best place to swim or float in the lake is at Antelope Island State Park, where white oolitic sand beaches provide easy access to the lake without the brine flies that are prevalent on other areas of the shoreline. The beach area also has showers to rinse off the salty water.
Climate change isn't only causing wildfires and massive heat waves, but it's drying up vital bodies of water such as the Great Salt Lake bordering the Salt Lake Valley.
Great Salt Lake has ranged in salinity from about 5 percent to 27 percent over the past 22 years. This is two to nine times saltier than the ocean's 3 percent. At present Farmington Bay is approximately 5 percent salt, while the North arm is 26 percent and the South arm is 14 percent.
Great Salt Lake is an average of just 14 feet deep, with a maximum depth of 33 feet. Its shallow depth means that much of its surface area is exposed to the air, and is subject to its seasonal temperature fluctuations.
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.
