What Is the Water Level Function in the Navionics Boating App?

The Water Level function allows you to adjust shoreline and depths to the current lake level, and is available with an active subscription in the Navionics® Boating app.  Adjusting the setting in a positive direction will raise the water level for times of a flood pool. Moving the slider in a negative direction will lower the water level in cases of drought or when a lake is physically drained.

If the Water Level is changed to a positive number (indicating that the water is deeper than referenced on our original charting) it will cause a hazard warning to appear on your map screen. Tap the symbol to get more information.

To reset the depth information to display as it would in our original chart database, set your Water Level to 0 ft/mt/fm.
