Great Salt Lake Level and Volume Time Series

Time series of level, area and volume in the Great Salt Lake from the earliest South Arm level record on 10/18/1847 to 10/5/2024. 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.

GSL_north_arm.txt is measured data from the USGS station 10010100 GREAT SALT LAKE NEAR SALINE, UT

GSL_south_arm.txt is measured data from the USGS station 10010000 GREAT SALT LAKE AT SALTAIR BOAT HARBOR, UT

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.
WyrAveLevels.csv is time series of average water year level

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.

大盐湖水位、面积和体积的时间序列数据，始于1847年10月18日最早的南岸水位记录，至2024年10月5日。大盐湖的体积和面积是通过记录的水位和测深数据计算得出。所使用的测深数据包含在内。测深数据已根据镁质淤积池的存在与否进行调整。蒸发池的面积在建设之前及其溢出期间不视为湖泊的一部分。

GSLLAV.txt 文件记录了使用测深数据计算得出的水位、面积和体积的时间序列数据。
GSLLevelVol.csv 文件记录了每月初的水位和体积时间序列数据。当月份的第一天没有观测数据时，将进行插值。
WyrAveLevels.csv 文件记录了平均水年的水位时间序列。

标题应清晰可辨。请注意，北岸的水位记录仅从1966年开始单独记录，因此在1966年之前的数据，北岸水位取自南岸。然后使用测深数据分别计算每条臂的面积和体积，并将它们相加。
