Changes in lake levels affect air quality, wildlife habitat, mineral extraction, and water availability for communities across the state. This tracker provides clear, up-to-date data to help Utah residents, policymakers, and advocates understand trends, risks, and the impact of water use decisions—supporting informed action to protect the lake’s future.Great Salt Lake Water Level%CollapseCriticalHealthyGreat Salt Lake water level data comes from USGS monitoring stations at the  Saltair Boat Harbor and at Saline, UT. These data are averaged for the  previous day at midnight each day, which is why our tracker displays  yesterday’s date.0feet below the minimum healthy levelGreat Salt Lake’s minimum healthy water level is 4,198’.0of the lakebed is exposedCompared to the lake area at its natural elevation of 4,207’.0square miles of exposed lakebedMore exposed lakebed reduces habitat and increases dust storms0FullCompared to the lake volume at its natural elevation of 4,207’.0Salinity12-16% salinity is ideal for brine shrimp.0South Arm ElevationThe 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.
