Great Salt Lake Elevations and Areal Extent

Great Salt Lake is unique among lakes in the Western Hemisphere because of its size and salt content. It occupies a low part of the desert area of western Utah and is a terminal lake with no outlet to the sea. It varies considerably in size, depending on its surface elevation. At an elevation of 4,200 feet above sea level, it covers approximately 1, 700 square miles and contains about 16 million...

Quantifying Nutrient Mass and Internal Cycling in Great Salt Lake

The Great Salt Lake (GSL) is an indispensable economic and ecological resource. It provides critical habitat and food for millions of migratory birds, and generates nearly $200 million per year from recreational activities and the brine shrimp harvest industry (Bioeconomics, 2012). These uses, habitat and aquaculture, rely on a balanced supply of nutrients in the Great Salt Lake to support...

General Information, Facts, News, Publications and Partners

The western part of the conterminous United States is often thought of as being a desert without any large bodies of water. In the desert area of western Utah, however, lies Great Salt Lake, which in 1986, at its highest level, covered approximately 2,300 square miles and contained 30 million acre-feet of water (an acre-foot is the amount of water necessary to cover 1 acre of land with water 1...

Studies of Sources and Transport of Dissolved Solids (Salt) in the Colorado River Basin using the Spatially Referenced Regressions on Watershed Attributes (SPARROW) Model The Upper Colorado River Basin (UCRB) encompasses about 112,000 mi2 and discharges more than 6 million tons of dissolved solids (salt) annually to the lower Colorado River Basin. It has been estimated that between 32 and 45...

Great Salt Lake - Fifty years of change through satellite images

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, the north arm became much more saline than the south; well defined in the satellite images. Several years of greater than normal precipitation resulted in a large increase in the lake’s area during the early 1980's and the creation of a new...

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 culverts...
