At its lowest, the lake's water surface elevation measured at 4,188.2 feet in November 2022. On Tuesday, a large crane lifted around 50 boats into the marina, which is seeing rebounding levels of water, according to The Salt Lake Tribune.
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!
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.
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.
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.
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.
“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.”
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.
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 saltiest of the Great Salt Lake's water sits on the bottom of the lake. The heavy brine traps organic material (i.e., algae and plant and animal remains) and gases at the bottom of the lake.
The Great Salt Lake is home to many important biological and wildlife species, from archaea, to bacteria, to phytoplankton (400+ species). Perhaps the three most apparent species that can be seen with the naked eye are brine shrimp (tons), brine flies (billions) and birds (millions).
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.
The drying of lakes and reservoirs around the world is increasingly stressing water supplies for drinking and agriculture, endangering habitats for plants and fish, reducing the capacity to generate hydropower, and threatening marine recreation and tourism.
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.
