Does the Great Salt Lake freeze over?

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.

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!

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.
