St. Marys and Nassau Rivers

Nassau County

This 125-mile river starts in the acid swamps of Okeefenokee and becomes a tidal river below US 17 north of Jacksonville. Upstream is redbreast sunfish and small largemouth bass territory. The salt marsh zone is famous for striped bass (the same is true for nearby Nassau River).

Both coastal rivers allow anglers to catch a variety of freshwater species. When fishing the Saint Marys River, stay abreast of Florida and Georgia regulations as rules change depending on your location. In the upper reaches of these rivers, in areas of greater freshwater concentrations, black bass, panfish, and catfish can all be taken. The St. Marys River is known for its healthy bluegill and redbreast sunfish populations. The shallower, vegetated banks are these rivers' most productive sunfish habitats. Woody snags or downed trees should be targeted as well. Live baits, such as worms and crickets, are great choices for sunfish in these waters. Both the Nassau and the St. Marys River have good populations of Florida bass as well. Targeting cypress stands and other woody structures with soft plastics or jigs along river shorelines is a great way to fish for bass. Good bass fishing can be found in the areas around King’s Ferry, Boulogne, and St. George. In the lower stretches of these rivers, anglers can fish for various saltwater species, including drum, sea trout, and flounder. Live bait is an effective way of taking these species, with mud minnows, shrimp, and crabs being popular choices. Artificial jigs and plugs are two effective ways to target these fish as well. Areas to target include current breaks, woody structures, and hard bottom areas. Deeper holes should not be overlooked, as colder weather can drive fish into areas insulated from cooling air temperatures. Check the local tide charts and plan your trip around the tides. Fish are more active during rising and falling tides than slack water times. The best location for hitting striped bass would be in the lower stretches of the St. Marys River, between I-95 and the town of St. Marys. Trolling plugs and casting shad-imitating jigs in deeper holes should attract any fish in these areas.
