Great Salt Lake Brine Density and Chemistry Hub

The salinity level of Great Salt Lake (GSL) is quite dynamic due to natural lake level fluctuations and man-made barriers within the lake. At a number of sites throughout the lake, the UGS takes samples at various depths through the water column, measures those samples for density, and analyzes them for chemistry. This sampling program has largely been funded by the Utah Division of Forestry, Fire and State Lands.

Great Salt Lake is likely best known for its high salinity and large size. Yet this unique lake also supports mineral and brine-shrimp industries, provides a resting place for millions of migratory birds, and reveals varied spectacular sights. Sunsets over distant islands, white beaches, and water colors ranging from blue to pink offer inspiration for artists. Antelope Island, Great Salt Lake, Utah. Photographer: Carole McCalla
