Even when the water temperature is in the 20's (°F), the lake does not freeze, due to the high salt content of the water; but icebergs have been ob- served floating on the lake's surface, formed from freshwater that flows into the lake from tributaries and freezes on the surface before it mixes with the brine.

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 ...

Great Salt Lake is between 3.5 and 8 times saltier than the ocean. The organisms that live in the water have special adaptations that allow them to survive such saline conditions. Air blocks much of the sun's DNA-damaging ultraviolet light from reaching the surface of the earth.

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.

Lake Levels Due 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!

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 Great Salt Lake is the largest saltwater lake in the Western Hemisphere and the eighth-largest terminal lake in the world. It lies in the northern part of the U.S. state of Utah and has a substantial impact upon the local climate, particularly through lake-effect snow.

In the 1950s, the bridge was rebuilt with rock, creating a causeway that severs the lake's North Arm from its major sources of fresh water. As a result, the North Arm has grown increasingly salty and hostile to most life, except for microorganisms like halobacteria and red algae that thrive there and give it its color.

The Smell of the Great Salt Lake There are a handful of different reasons for this. The first is that the lake carries huge amounts of salinity. This means that less bacterial sulfates which make hydrogen sulfide. A second source of the lake smell is the combination of low depth and low oxygen where the lake is.
