Suwannee and Santa Fe Rivers

During flood conditions, certain portions of flood-prone rivers are established by rule as “Idle Speed/No Wake” for the purpose of regulating the speed and operation of vessel traffic for public safety. These zones are determined by Florida Administrative Code and flood levels are dependent upon NOAA/USGS flood gauge readings. See the following information about zone activations due to flooding.

NOTE: Information is updated Monday - Friday by 5 p.m. Eastern Time.
