Boating Advisories
Important Change in River Level Measurements

Beginning in August 2016, the District will start implementation of the use of a new vertical datum, the North American Vertical Datum of 1988 (NAVD88).  In the past, the District has used the National Geodetic Vertical Datum of 1929 (NGVD29).  The new datum will result in a downward shift of between 0.64 to 0.90 feet depending on location.  There is no change in the actual river level, only the value used to represent the level is different.  The full conversion is expected to be complete by November 1, 2016.

More information about the vertical datum change may be found at or by calling the District offices at 386-362-1001 and asking to speak with Tom Mirti, Director of Water Resources.  

Idle Speed/No Wake

The Florida Fish and Wildlife Conservation Commission (FWC) has established idle speed, no wake zones for the Suwannee and Santa Fe rivers. These zones will be enforced by the FWC for individual segments of the rivers when water rises to specific levels. Idle speed, no wake means a vessel must proceed at a speed no greater than required to maintain steerageway and headway.

Report boating violations to FWC dispatch toll free at 1.888.404.3922.

Please visit our Current River and Lake Levels page for no wake notices.
