Nassau Sound Fishing from Amelia Island: Where River Meets Ocean

Nassau Sound: An Overlooked Fishery

Nassau Sound sits at the southern end of Amelia Island where the Nassau River, Fort George River, and several major tidal creeks converge before emptying into the Atlantic Ocean. The sound functions as a massive mixing zone where freshwater flow from the interior meets ocean saltwater on every tide cycle. This nutrient exchange supports an extraordinary forage base—shrimp, crabs, mullet, menhaden, and small baitfish—that attracts predators ranging from redfish fishing targets in the creeks to tarpon and sharks at the sound's ocean mouth.

Nassau Sound does not have the name recognition of the St. Johns River or the Indian River Lagoon, and that relative anonymity works in an angler's favor. Fishing pressure stays low year-round, particularly in the back creeks and marsh flats that hold the best inshore action.

Fishing Zones Within the Sound

Back Creeks and Marsh Flats

The tidal creeks feeding into Nassau Sound from the west—Simpson Creek, Clapboard Creek, and the channels winding through Big Talbot Island—hold redfish and seatrout on their oyster-lined banks and grass-edged flats. At high tide, redfish push deep into the Spartina marsh, tailing on flooded grass as they feed on fiddler crabs. At low tide, fish pull back to the creek channels and oyster bar edges. A kayak or shallow-draft skiff is the only way to access most of this water.

Main Sound Channel

The deeper channel running through the center of Nassau Sound holds flounder, sheepshead fishing targets around structure, and seasonal concentrations of black drum. The channel edges where sand meets oyster or rock produce the most consistent flounder bites, particularly during outgoing tides when current sweeps bait from the creeks into the deeper water.

Sound Mouth and Nearshore

Where Nassau Sound opens to the Atlantic, the tidal rip creates a fertile zone for larger predators. Tarpon cruise the sound mouth from May through September, visible by their rolling behavior on calm mornings. Jack crevalle run in schools that attack any bait or lure in their path. Bull redfish congregate here in fall. And during summer months, spinner and blacktip sharks patrol the turbid water hunting schools of mullet and menhaden.

Seasonal Highlights

Spring Flounder Run (March–May)

Flounder move from deeper offshore water back into the sound system as temperatures warm. They take up ambush positions on the sandy channel edges, particularly near the spoil islands and creek mouths. A live mud minnow or finger mullet on a 1/4-ounce jighead, bounced slowly along the bottom, produces the most consistent results. The flounder fishing window extends through May before summer heat pushes fish into deeper holding areas.

Summer Tarpon (June–August)

Tarpon ranging from 50 to 150 pounds enter Nassau Sound on incoming tides during summer months. They roll on the surface in the deeper parts of the sound, particularly near the old pilings and channel edges. Live mullet or menhaden on heavy tackle (7-foot heavy spinning rod, 50-pound braid, 60-pound fluorocarbon leader, 7/0 circle hook) gives you a realistic chance at hooking one. Fighting a tarpon in the strong current of Nassau Sound tests every piece of equipment.

Fall Mullet Run (September–November)

The fall mullet migration through Nassau Sound triggers the best fishing of the year. Every species in the system keys on the mullet run—redfish, trout, flounder, jacks, tarpon, and sharks all feed aggressively. Casting live or cut mullet into feeding frenzies produces non-stop action. Artificial lures that mimic mullet—4-inch white paddletails, silver topwater plugs—work nearly as well when fish are in a competitive feeding mode.

Nassau Sound borders Big Talbot Island and Little Talbot Island State Parks. These parks provide beach access, kayak launches, and trail systems that enhance a fishing trip to the area. The FWC redfish regulations set the slot at 18 to 27 inches with a one-fish daily bag limit. Bull redfish caught at the sound mouth must be released.

Getting There and Getting On the Water

• Boat ramp at George Crady Fishing Bridge State Park: Access to the sound from the A1A bridge—convenient for boats and kayaks
• Simpson Creek kayak launch: Put in from Big Talbot Island for access to the back creeks and marsh flats
• Nassau Sound Bridge (A1A): Bank fishing from the bridge shoulders for sheepshead, drum, and seasonal flounder
• Little Talbot Island beach: Surf fishing access to the nearshore zone adjacent to the sound mouth for pompano and whiting
