Understanding Charted Depths and Lake Monroe Water
Levels
Depths on a NOAA chart in Lake Monroe are based on a
gage height of 0.09 feet which represents mean lower low water. Vertical
clearances on a NOAA chart in Lake Monroe are based on a gage height of
3.7 feet which represents mean high water. There is no tidal range this
far south on the river. The following example shows current water
level (gage height) and the affect on chart depths and clearances:

Information below provided by NOAA Advanced Hydrologic Prediction
Service and observed water levels (Stage) at the Interstate-4 bridge
West of Lake Monroe every thirty minute.
Take the latest stage reading above and match that number to find
water depth.
