The South Arm of Great Salt Lake is measured from the USGS monitoring station at Saltair Boat Harbor. This measurement is usually what is looked at when considering the health of the lake. The minimum healthy level is 4198′ above sea level
The North Arm of Great Salt Lake is measured at the USGS monitoring station at Gilbert Bay.

Data Sources
The National Water Dashboard allows you to create maps showing where things like reservoirs, rivers, watershed boundaries, and more are in a selected region.
Between 60-70% of Utah’s water comes in the form of snow, though it can be hard to know how much water is actually held in the snow. Snow-water equivalent calculates how much water is available in the snow, which varies depending on climate conditions.
This resource shows how much precipitation accumulates in Great Salt Lake over time.
Soil moisture is an indicator of drought and can predict both future drought and flood conditions. This resource shows soil moisture percentages throughout the Great Salt Lake watershed.
Other Dashboards
The Great Salt Lake Hydromapper is a resource from the USGS that shows changes in lake level, volume, and salinity over time. It also has information about other health indicators for the lake.
The Utah Department of Natural Resources has also created a dashboard with links to various sources of Great Salt Lake data.
