Great Salt Lake Elevations

Great Salt Lake Elevations

The United States Geological Survey (USGS) has been collecting water-surface-elevation data from Great Salt Lake since 1875 and continuously since October 1902. The north part of the lake has been monitored since April 1966.

Earthshots 1972-2016: Satellite Images of Environmental Change

Dramatic changes in lake levels are observed in these images from 1972-2016. The completion of the Railroad Causeway in 1959 divided the Great Salt Lake in half. Because all of the freshwater inflows enter the southern part of the lake and evaporation is greater in the northern part, the north arm became much more saline than the south; well defined in the satellite images. Several years of...

Great Salt Lake

Great Salt Lake is located on a shallow playa. Consequently, small changes in the water-surface elevation result in large changes in the surface area of the lake. This is particularly evident when the lake spills into the west desert at an elevation of about 4,215 feet, greatly increasing its area. The satellite imagery shows changes in the area of the lake from 1972, through the high-runoff...

Deep Brine Layer

In 1959, a solid-fill railroad causeway was constructed across the middle of the Great Salt Lake. The construction of the causeway divided the lake into two parts; the north (Gunnison Bay) and the south (Gilbert Bay). By 2013, water flowed from one side to the other through only two culverts near the center of the causeway. In December 2013, concern about the structural integrity of the...

Great Salt Lake Nutrients: Inflows and Gilbert Bay

Great Salt Lake is a hypersaline terminal lake and is an important habitat for migratory waterfowl. It is sensitive to climate and human-induced changes, and both make the long-term outlook for the lake uncertain. Because Great Salt Lake is near a populated area, there is an increased demand for the water that feeds the lake, and there is an increased risk for elevated concentrations of...
