How full is Allatoona Lake?
USGS publishes the water surface elevation for this gauge but not a percent-full figure, so we don't show one rather than estimate it.

The page is rebuilt automatically every day from USGS's published data. Values can be revised later by the source agency.
Where does the data come from?
The U.S. Geological Survey's Water Data API (api.waterdata.usgs.gov), which publishes readings from USGS and partner gauges. Forecasts come from the National Weather Service.
