Lake Pontchartrain is more than just a scenic backdrop to southeast Louisiana—it’s a fishing paradise steeped in culture, variety, and year-round opportunity. Whether you’re an experienced angler or just looking to cast a line on the weekend, this ultimate guide will walk you through the best fishing spots, the top species to target, and pro tips to make your trip a success.
Why Fish in Lake Pontchartrain?
At over 600 square miles, Lake Pontchartrain isn’t technically a lake—it’s an estuary. That means it boasts a mix of freshwater and saltwater species, making it one of the most diverse fishing environments in the Gulf South. You’ll find everything from speckled trout and redfish to bass and catfish, and the brackish waters support healthy populations year-round.
Plus, the lake’s proximity to cities like New Orleans, Mandeville, and Slidell means easy access to public piers, marinas, and bait shops. Whether you’re fishing from a boat or the shore, the lake is ready to provide a great catch—and maybe even dinner.
Best Fishing Spots Around Lake Pontchartrain
From bridges to bayous, here are the top locations to cast a line.
1. The Lake Pontchartrain Causeway
At 24 miles long, the Causeway Bridge offers prime fishing along its pilings, especially if you’re in a boat. Speckled trout, redfish, and black drum are frequently caught here. The underwater structure provides excellent cover for baitfish, which in turn attracts larger game.
For boat owners, consider docking at one of the many nearby boathouse-accessible properties that make lake fishing more convenient.
2. The Trestles (Slidell)
The old railroad bridge, known locally as “The Trestles,” is a hot spot for anglers targeting speckled trout. Its submerged structure creates ideal fishing conditions, especially during spring and fall. You’ll need a boat to access this area safely, but the payoff is well worth it.
3. Bayou St. John
This historic waterway flows into Lake Pontchartrain near New Orleans and offers fantastic fishing opportunities for bass and sheepshead. Kayakers and shore anglers often find success here with soft plastics and live shrimp.
4. Seabrook Bridge
Located near the lake’s connection to the Industrial Canal, the Seabrook Bridge is a popular location for both shore and boat fishing. It’s especially known for trout, redfish, and flounder during the warmer months.
5. Fontainebleau State Park
On the north shore near Mandeville, this state park has piers and shoreline access perfect for families or anglers without a boat. You’ll find bream, catfish, and even the occasional trout.
Fish Species You’ll Find in Lake Pontchartrain
Fishing in Lake Pontchartrain is all about variety. Here’s what you can expect to reel in.
Speckled Trout (Spotted Seatrout)
One of the most targeted species in the lake, speckled trout are aggressive, plentiful, and delicious. They’re often found near bridge pilings, drop-offs, and where fresh and saltwater mix.
- Best bait: Live shrimp, plastic paddle tails, topwater lures
- Peak season: Spring and fall
Redfish (Red Drum)
Redfish thrive in the lake’s shallow marshes and grassy flats. These hard-fighting fish are a favorite among sport anglers and can grow to impressive sizes.
- Best bait: Crab, shrimp, soft plastics
- Peak season: Year-round
Black Drum
Younger black drum are often confused with redfish, but older ones grow much larger—up to 60 pounds. You’ll usually find them near bridges and deeper channels.
- Best bait: Crabs, cut bait
- Peak season: Winter and early spring
Flounder
These flatfish are known for their camouflage and sudden strikes. Look for them near sandy bottoms and tidal inlets.
- Best bait: Mullet, soft plastic jigs, shrimp
- Peak season: Fall
Bass
Yes, you can catch bass in Lake Pontchartrain! The freshwater influx from rivers and bayous creates pockets where largemouth bass thrive, particularly on the northern side of the lake.
- Best bait: Spinnerbaits, frogs, crankbaits
- Peak season: Spring and early summer
Tips for a Successful Day of Fishing
Fishing in Lake Pontchartrain is as much about preparation as it is luck. Here are some essential tips to increase your chances of a great catch.
Check the Weather and Tides
This estuarine lake is highly influenced by tide changes and wind. A moving tide generally means better fishing. Use apps or NOAA forecasts to plan around ideal times.
Use the Right Gear
A medium-action spinning rod and 10–20 lb test line are great all-around options. Don’t forget a landing net and long-handled pliers—some species have sharp teeth or spines.
Match Your Bait to the Species
Live shrimp work well for almost everything, but artificial lures like topwaters, paddle tails, and jerkbaits can be just as effective depending on the conditions.
Stay Safe on the Water
If you’re fishing by boat, make sure your equipment and safety gear are in good shape. The lake can kick up quickly with wind. Always wear a life jacket, especially near bridges.
Respect Local Regulations
Always follow Louisiana Department of Wildlife and Fisheries rules regarding size limits, daily catch limits, and fishing licenses. The rules can vary by species and season, so check ahead.
Fishing With Family? Here’s What to Know
Lake Pontchartrain is a great place to introduce kids to fishing. Many areas offer easy access, public restrooms, and picnic spaces. Fontainebleau State Park and the Mandeville Lakefront are both family-friendly and safe.
You can also create a long-term gathering spot with a custom boathouse or pier where you and your family can fish, relax, or launch kayaks. It’s a lifestyle investment that pays off in memories.
What Makes Lake Pontchartrain Unique
Lake Pontchartrain’s unique blend of saltwater and freshwater creates an ecosystem unlike any other in the U.S. It’s this balance that gives the lake its diversity—and why anglers from all over keep coming back.
The bridges, submerged structures, and marshy outlets create a natural habitat that supports fish spawning and growth. Plus, the lake’s sheer size means there’s room for everyone—whether you’re after a quiet morning in the marsh or an action-packed day under the Causeway.
