Bayou St. John is a tidal estuary running through New Orleans, offering year-round fishing for redfish, speckled trout, and catfish within the city limits

Bayou St. John stretches roughly seven miles from Lake Pontchartrain south through the Tremé and Gentilly neighborhoods to its junction with the Industrial Canal. The water is brackish—a mix of freshwater and saltwater—because it connects directly to the lake and experiences tidal flow. This means the salinity and water level change throughout the day, which affects where fish hold and what species you'll find at any given time.

The bayou is accessible from multiple public launch points and shoreline access areas, making it one of the few places in New Orleans where you can fish without a boat. Redfish and speckled trout dominate the catch, especially in fall and spring. Catfish are present year-round. The water quality varies depending on recent rainfall and tidal conditions, and you should check local reports before heading out.

Key Takeaways

  • Bayou St. John is tidal and brackish, so fish location and species composition shift with the tide and time of year.
  • Public boat launches exist at the north end (near Lake Pontchartrain) and at several points along the bayou, with parking available at most.
  • Redfish and speckled trout peak in fall (September through November) and spring (March through May), while catfish bite year-round.
  • Shore fishing is possible at designated public access points, though boat access gives you more water to cover and better chances at larger fish.
  • Louisiana fishing licenses are required; saltwater stamps are needed because the bayou is classified as coastal water.

Public Access and Launch Points

The most popular public launch is at the north end, near the Bayou St. John Fishing Pier and the area adjacent to Lake Pontchartrain. This launch has a concrete ramp, parking, and restroom facilities. It's the easiest entry point if you're towing a trailer, and it puts you in deeper water immediately.

Mid-bayou access exists at several smaller public areas, including spots near Esplanade Avenue and along the Industrial Canal approach. These are better for kayaks, canoes, or small skiffs than for trailered boats. Parking is limited at these locations, and some are day-use only. Check with the New Orleans Parks and Recreation Department or the Audubon Commission for current access status, as maintenance and closures can change seasonally.

Shore fishing is possible at the Bayou St. John Fishing Pier (north end) and at scattered public rights-of-way along the bayou, though private property lines are strict in residential areas. Bring a map or use a GPS app to confirm you're on public land before setting up.

Seasons and What Fish Are Biting

Fall (September through November) is the peak season. Water temperatures drop from summer heat, and redfish and speckled trout move into the bayou to feed before winter. Tides are more stable, and water clarity improves. Expect the best action on incoming tides during early morning and late afternoon.

Spring (March through May) is the second-best window. Fish are moving back into shallow water after winter, and spawning activity drives feeding. Water levels can be high due to spring runoff, which can muddy the water, but fish still feed actively. Speckled trout are particularly aggressive in April and May.

Summer (June through August) is slow. Heat stresses fish, and they move into deeper water or toward the lake. Catfish remain active, especially at night. If you fish summer, target early morning or dusk, and focus on deeper holes and channel edges.

Winter (December through February) is unpredictable. Cold snaps can shut down fishing for days, but mild spells can produce good action. Redfish and trout are still present but less aggressive. Catfish remain a reliable option. Water levels are often lower, which concentrates fish in deeper areas.

Tackle, Bait, and Technique

For redfish and speckled trout, light to medium spinning tackle works well. Use 8- to 12-pound test line and 12- to 20-pound fluorocarbon leader. Topwater plugs, soft plastics (3 to 4 inches), and live shrimp all produce. Cast near structure—fallen trees, dock pilings, marsh grass edges—and work the bait slowly. Redfish often hunt in very shallow water, sometimes with their backs exposed; speckled trout prefer slightly deeper edges.

Catfish respond to cut bait (mullet, mackerel, or shrimp) fished on the bottom with a simple three-way rig or slip sinker setup. Use heavier tackle (12- to 20-pound line) because catfish fight hard and the bayou bottom is snaggy. Fish at dawn, dusk, or night for best results.

Tidal timing matters. Incoming tides generally produce better fishing because water movement triggers feeding. Slack tide (the period between incoming and outgoing) can be slow. Check tide tables for New Orleans before you go; the bayou's tides are predictable and follow Lake Pontchartrain's cycle.

Regulations and Licensing

You must have a valid Louisiana fishing license. Because Bayou St. John is classified as coastal water (it connects to the Gulf via Lake Pontchartrain), you also need a saltwater fishing stamp, even though the water is brackish. Licenses are sold online through the Louisiana Department of Wildlife and Fisheries website, at sporting goods stores, and at many bait shops in New Orleans.

Bag limits and size restrictions vary by species and change annually. Redfish have a minimum size (typically 18 inches) and a daily bag limit (usually two fish). Speckled trout have a minimum size (typically 12 inches) and a daily limit (usually 25 fish). Catfish have no size restriction but do have a daily bag limit. Check the current regulations on the LDWF website before you fish; regulations are updated each year and sometimes mid-season.

Catch-and-release is always legal if you follow size and bag limits. If you plan to keep fish, bring a cooler with ice.

Water Quality and Safety Considerations

Bayou St. John's water quality depends on rainfall and tidal exchange. After heavy rain, freshwater runoff can lower salinity and reduce visibility. During dry periods, the water is clearer and more saline. Check local fishing reports or call a bait shop before heading out to learn current conditions.

The bayou runs through an urban area, so boat traffic can be heavy, especially on weekends. Wear a life jacket, keep your boat visible, and stay alert. The bottom is soft mud and can be snaggy; use breakaway rigs or accept that you'll lose some tackle.

Alligators are present but rarely aggressive toward anglers. Keep a safe distance, do not feed them, and avoid wading in shallow water at dawn or dusk. Mosquitoes can be intense, especially in summer and after rain; bring insect repellent.

Nearby Resources and Bait Shops

Several bait and tackle shops near the bayou stock live shrimp, cut bait, and tackle. These shops also post current fishing reports and can advise on recent catches and water conditions. Shops near the north end (Lakeview area) and along Esplanade Avenue are closest to the bayou. Call ahead to confirm hours and bait availability, especially in winter.

The Audubon Commission and New Orleans Parks and Recreation maintain the public access areas and can answer questions about closures or maintenance. The Louisiana Department of Wildlife and Fisheries publishes fishing advisories and updates regulations online.

Frequently Asked Questions

Do I need a boat to fish Bayou St. John?

No. The Bayou St. John Fishing Pier and several public shoreline areas allow shore fishing. A boat gives you access to more water and deeper holes, but you can catch redfish and trout from shore, especially during incoming tides and in fall and spring.

What's the best time of day to fish?

Early morning (sunrise to mid-morning) and late afternoon through dusk are most productive. Combine this with an incoming tide for the best results. Catfish bite well at night, but redfish and trout are more active during daylight hours.

Can I fish in winter?

Yes, but conditions are variable. Cold snaps can shut down fishing, but mild days can produce good action. Catfish remain reliable year-round. Winter water levels are often lower, concentrating fish in deeper holes and channel edges.

What should I do if I hook a large fish near structure?

Keep steady pressure and avoid letting the fish wrap around pilings or fallen trees. Use a heavier leader (20-pound test) if you're fishing near structure. If the fish gets wrapped, try backing off slightly to give it room to move, then reapply pressure. Accept that some fish will be lost to snags.

Is the water safe to eat fish from?

Check current fish consumption advisories from the Louisiana Department of Health and Hospitals before keeping fish. Advisories change based on water quality testing and can vary by species and location within the bayou. When in doubt, contact the department or a local bait shop.
