How full is Bennington 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.

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.
