A living lake.
A shared future.
The Great Salt Lake supports ecosystems, communities, and livelihoods. Lady Lake starts with a simple idea: more people should feel connected to its recovery.

Part of a bigger story.
What we measure
Water-surface elevation at USGS station 10010000, Saltair Boat Harbor, in the lake’s south arm. The unit is feet above NGVD 1929—not depth, water volume, or a percentage of recovery.
What “healthy range” means
The shaded band marks 4,198–4,205 feet, the optimal range shown in Utah’s Great Salt Lake elevation matrix. Salinity, habitat, and other conditions also matter; a single gauge cannot describe the whole lake.
Read the range explanation ↗How it updates
The page requests the latest USGS observation when opened and every 15 minutes while open. Readings may be cached for up to five minutes. “Observed” is the measurement time, not the time you opened this page.
What “provisional” means
USGS may revise a measurement after review. We flag provisional data, label readings over 24 hours old, and show an unavailable state if the feed cannot be reached. The gauge does not use an invented backup reading.
