What Graveline Bayou offers and how to fish it
Graveline Bayou is a shallow, brackish system about 15 miles east of Ocean Springs that holds redfish and spotted seatrout year-round, with the best fishing in fall and spring when water temperatures stabilize. The bayou runs roughly north-south, averaging 4 to 6 feet deep in the main channel but dropping to 2 feet or less across the flats, and it connects to Mississippi Sound through a series of narrow passes that concentrate fish during tidal movement. Unlike the deeper Gulf channels, Graveline rewards sight-fishing and light tackle—you can see redfish tailing in the shallows and take them on topwater or soft plastics without heavy gear.
The system is accessible by boat from Ocean Springs marinas, a 20 to 30-minute run depending on which launch you use. Most anglers fish the flats on either side of the main channel during low tide when redfish move into 18 inches of water to feed, then work the deeper holes and drop-offs as the tide rises. Spotted seatrout prefer the slightly deeper edges and channel structure, so your approach changes depending on what you're targeting and what the tide is doing.
Key Takeaways
- Graveline Bayou holds redfish and spotted seatrout in shallow water, making it ideal for sight-fishing and topwater lures rather than deep-water jigging.
- Low tide concentrates redfish on the flats in 18 inches of water or less; rising tide pushes them into deeper holes and channel structure.
- The bayou is accessible by boat from Ocean Springs in 20 to 30 minutes, and most productive fishing happens in fall and spring.
- Soft plastics rigged on light jigheads and topwater plugs work best; heavy conventional tackle is unnecessary and often counterproductive in these shallows.
Tides and seasonal timing
Graveline Bayou is tidal water, and the tide controls where fish are and how they feed. On a falling tide, redfish move from the deeper channel onto the flats to hunt shrimp and small baitfish in water so shallow you can see their backs. This is the prime window for sight-fishing—you pole or drift slowly, spot a fish, and cast ahead of it. As the tide bottoms out, fishing slows because fish are scattered and less active. When the tide rises, redfish retreat to the channel and deeper holes, and spotted seatrout move up from the sound to feed along the drop-offs and structure.
Fall (September through November) and spring (March through May) are the most consistent seasons. Water temperatures are moderate, baitfish are abundant, and both redfish and trout are actively feeding. Summer can be productive early and late in the day, but midday heat pushes fish into the deepest holes. Winter is fishable but slower—redfish and trout move to the deepest channels and are less aggressive, though a warm day can trigger feeding.
Tackle and lures for shallow-water fishing
Graveline Bayou is not a place for heavy conventional tackle or deep-water jigging. A 6 to 7-foot medium-light spinning rod with 15 to 20-pound braid and a 12 to 15-pound fluorocarbon leader is the standard setup. Braid gives you sensitivity to feel bottom and detect strikes in shallow water, and fluorocarbon is less visible to fish in clear shallows. Keep your drag set so a redfish can take line without breaking off, but tight enough that you can set the hook on a trout.
Topwater plugs work best on a falling tide when redfish are shallow and aggressive. Walk-the-dog style lures like a Rapala Skitter Walk or Heddon Zara Spook create commotion that draws strikes from 20 feet away. Soft plastics on 1/8 to 1/4-ounce jigheads are your workhorse for both redfish and trout—throw them near structure, along drop-offs, and on the edges of deeper holes. Shrimp-pattern plastics and small mullet imitations both work. Live shrimp under a popping cork is effective if you want to slow down and fish more deliberately, especially for trout along the channel edges.
Where to fish: flats, channels, and structure
The main channel runs down the center of Graveline Bayou and is the highway fish use to move with the tide. On a rising tide, work the drop-offs on both sides of the channel with soft plastics or live shrimp—redfish and trout both hunt along these transitions. The channel itself is 5 to 6 feet deep and holds fish when the tide is high and the flats are flooded.
The flats on either side of the channel are where sight-fishing happens. On a low or falling tide, pole or drift slowly and look for redfish tailing, cruising, or pushing water. Cast ahead of the fish and work your lure back slowly—redfish in shallow water are easily spooked by a fast retrieve or a lure that lands too close. Spotted seatrout prefer slightly deeper water and structure, so focus on the edges where the flats drop into the channel rather than the shallowest areas.
Oyster bars and grass beds hold both species and provide cover for baitfish. If you see a concentration of mullet or shrimp, fish it—redfish and trout will be nearby. The passes that connect Graveline to Mississippi Sound concentrate fish during tidal movement, especially on an outgoing tide when baitfish are flushed out and predators gather to feed.
Boat access and navigation
Most anglers launch from Ocean Springs marinas like Biloxi Bay Marina or Broadwater Boat Rentals and run east toward Graveline. The run takes 20 to 30 minutes depending on which part of the bayou you're targeting. The water is generally calm and well-marked, but shallow areas and oyster bars require attention—run at idle speed in water shallower than 3 feet and watch your depth finder. A shallow-draft skiff or flats boat is ideal, but a center-console with a jackplate can work if you're careful.
Graveline is open water, so weather can change quickly. Check the forecast before you go, and don't venture into Mississippi Sound if wind is picking up—the sound can get rough fast. The bayou itself is protected, but the passes to the sound are exposed. Most productive fishing happens in calm conditions when you can see the bottom and fish are more active.
What to expect: species and typical catches
Redfish are the primary target in Graveline Bayou. Fish range from 18 inches to 28 inches, with occasional larger fish in the deeper holes. They're aggressive on topwater and soft plastics, and they fight hard in shallow water—expect a redfish to make a long run and test your drag. Spotted seatrout are secondary but consistent, especially along the channel edges and deeper structure. Trout are typically 15 to 22 inches and prefer live shrimp or small soft plastics. Both species are year-round residents, so you won't go fishless, but fall and spring produce the most active feeding and the largest fish.
Mullet, ladyfish, and small catfish are common bycatch. Mullet can be fun on light tackle, and ladyfish are aggressive and acrobatic. Catfish are less desirable but common in the shallows—if you're targeting trout and redfish, use a small hook and light leader to avoid attracting them.
Frequently Asked Questions
What's the best time of day to fish Graveline Bayou?
Early morning and late afternoon are most productive because light is lower and fish are more active. Midday can be slow, especially in summer. Time your trip around the tide rather than the clock—a falling tide in the afternoon is better than a rising tide at dawn.
Do I need a guide to fish Graveline Bayou?
No, but a guide is helpful if you've never fished shallow bayous. They know the tides, the structure, and where fish move throughout the day. If you're comfortable reading a depth finder and poling a skiff, you can fish it on your own.
Can I fish Graveline in winter?
Yes, but it's slower. Fish move to the deepest channels and are less aggressive. A warm day in January or February can trigger feeding, and you'll still catch redfish and trout, just fewer of them. Spring and fall are more reliable.
What size redfish are in Graveline Bayou?
Most redfish run 18 to 26 inches. Larger fish are present but less common. The shallow flats produce more consistent action on smaller fish, while the deeper channel holes hold occasional larger redfish.
Is Graveline Bayou good for beginners?
Yes. The water is shallow and protected, fish are abundant, and you can see what you're casting at. Start on a falling tide, focus on sight-fishing the flats, and use topwater lures—it's forgiving and fun for someone learning shallow-water techniques.
