EXPLANATION

The U.S. Geological Survey, in cooperation with the Utah Department of Natural Resources, Division of Forestry, Fire, and State Lands, 

collected bathymetric data for the north part of Great Salt Lake during the spring and early summer of 2006 using a single beam, high-definition 

fathometer and real-time differential global positioning system. Approximately 5.2 million depth readings were collected along more than 765

miles of survey transects for construction of this map. Sound velocities were obtained in conjunction with the bathymetric data to provide 

time-of-travel corrections to the depth calculations. Data were processed using commercial hydrographic software and exported into a 

geographic information system (GIS) software for mapping. Due to the shallow nature of the lake and the limitations of the instrumentation, 

contours above an altitude of 4,194 feet were digitized from existing USGS 1:24,000 source-scale digital line graph data. The Behrens Trench 

is approximately located.

For additional information on methods used to derive the bathymetric contours for this map, please see Baskin, Robert L., 2006, Calculation 

of area and volume for the North Part of Great Salt Lake, Utah, U.S. Geological Survey Open-File Report OFR–2006–1359.
