The Frederica River joins St. Simons Sound from the northward about 1 mile inside the entrance. Above its junction with Mackay River at the north end of Lanier Island, Frederica River extends northeastward for about 7 miles and rejoins Mackay River. This section is an alternate route of the Intracoastal Waterway. In 2004-2007, the reported midchannel controlling depth in Frederica River was 4.4 feet.
The fixed highway bridge crossing Frederica River from St. Simons Island to Lanier Island has a clearance of 9 feet. A strong east-to-west ebb current sets across the channel. During flood tide, the current flows northward in the direction of the channel and is very strong.
