 Below is an example of how to convert the Stage level to current water levels of Lake Koshkonong

The Datum Gage and Stage Level are measured in feet above sea level.
Datum Gage + Stage Level = Water Elevation Today 770.00   Datum Gage
+ 5.42    Sample Stage Level
775.42   Water Elevation Today
The Datum Gage is always 770.00. The Stage level varies with water elevations.
