How is the salinity of Great Salt Lake measured?
The salinity of Great Salt Lake is measured by taking specific gravity and temperature measurements and comparing them to standardized values reported in a table. Specific gravity is measured in the field by testing a water sample with a device very similar to a battery or antifreeze tester.

The Great Salt Lake
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 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...

Water-level and water-quality changes in Great Salt Lake, Utah, 1847-1983
The surface level of Great Salt Lake, Utah, fluctuates continuously, primarily in response to climatic factors. During 1847-1982 the lake surface fluctuated between a low of about 4,191 feet and a high of about 4,212 feet above sea level but showed no net change. From September 18, 1982, to June 30, 1983, however, the lake rose 5.2 feet-from about...

New Breach Allows Flow on the Great Salt Lake
The new Great Salt Lake breach was opened on Dec. 1 by the Union Pacific Railroad Company. This created a new opening between the north and the south arm of the lake, allowing water to flow between the two sides. This time-lapse video shows the breach opening, which took about two hours. Before the new breach was opened, the north arm of the Great Salt Lake was at an
