This describes work on the calculation of Great Salt Lake (GSL) inflows for modeling and analyses in support of declining lake levels. This derives from the procedures of USGS 00-4221 (Loving et al., 2000) who estimated GSL streamflow inputs for 12 years from 1987-1998, and Mohammed ant Tarboton (2012), who modeled GSL levels for 1950-2010 water years. Some deviations from the methods given in USGS 00-4221 (Loving et al., 2000) were necessary due to limited availability of data for the extended period and where there were opportunities for improvement.
