Abstract

Time series of level, area and volume in the Great Salt Lake from the earliest South Arm level record on 10/18/1847 to 10/6/2023. Volume and area of the Great Salt Lake are derived from recorded levels and bathymetry. The bathymetry used is included. Bathymetry is adjusted for the presence or absence of Magnesium corps pond. The area of the evaporation pond is not regarded as part of the lake except prior to its construction and during the time it was overtopped.

Headings should be obvious. Note that separate levels in the north arm only started being recorded in 1966 so for dates prior to that the North Arm Level is taken from the South Arm. The bathymetry was then used to compute area and volume in each arm separately and add them up.

GSLLAV.txt is time series of level, computed area and volume from level using bathymetry on the days of each observation

GSLLevelVol.csv is beginning of month time series of level and volume. This is interpolated when there is not an observation on the first day of the month.
