What You'll Find at Mandalay
Mandalay National Wildlife Refuge sits in the coastal marshes south of Houma, where the Atchafalaya River delta meets the Gulf. The refuge protects about 7,000 acres of brackish and saltwater marsh, shallow bays, and spoil banks—the ridges left behind when channels were dredged. You fish here for redfish, spotted seatrout, and flounder in water that ranges from a few inches to four or five feet deep depending on tide and location.
The refuge is open to fishing year-round, but access is limited to boats. There are no public boat launches inside the refuge itself, so you'll launch from Houma or from private marinas in the area and run south through the waterways. The refuge is managed by the U.S. Fish and Wildlife Service and sits adjacent to the Atchafalaya National Wildlife Refuge, so the two blend together on the water.
Key Takeaways
- Mandalay is a boat-only refuge with no public launches inside its boundaries; launch from Houma marinas and run south through marked channels.
- Redfish and spotted seatrout are the primary targets, with flounder and black drum also present in deeper holes and along shell ridges.
- Tides control water depth and fish movement in the shallow marsh; incoming tides push fish into the marsh, outgoing tides concentrate them in channels.
- Louisiana fishing licenses and saltwater permits are required; check current regulations for bag limits and closed seasons before you fish.
- Summer heat and mosquitoes are intense; early morning and late afternoon trips are more comfortable and often more productive.
How to Reach Mandalay and Launch Your Boat
The nearest public boat launch is at Houma, about 20 miles north. Southdown Marina, Atchafalaya Basin Marina, and several other private facilities in and around Houma offer launch ramps and fuel. From Houma, you run south through the Intracoastal Waterway or through marked channels that cut through the refuge. The run takes 30 to 45 minutes depending on which route you take and water conditions.
Once you're in the refuge, navigation is straightforward but requires attention. Channels are marked with red and green buoys. Shallow water and soft bottom are everywhere outside the main channels, so running at idle speed and watching your depth finder keeps you off the mud. Many anglers use shallow-draft boats—skiffs in the 18 to 22-foot range—because the water is often too shallow for larger center consoles.
Redfish and Seatrout in the Shallow Marsh
Redfish are the most reliable target in Mandalay. They hunt in water two to four feet deep, especially along the edges of marsh grass and around shell ridges. Incoming tides push them into the shallow marsh to feed; outgoing tides pull them back into deeper channels and holes. Early morning on a rising tide is often the most productive time, when fish are moving shallow and feeding actively.
Spotted seatrout prefer slightly deeper water—three to five feet—and concentrate around the deeper holes and channel bends. They're more active in spring and fall; summer heat pushes them into the deepest water available, and winter cold slows them down. Live shrimp and small mullet work for both species. Soft plastics on light jig heads are effective and easier to cast in the wind that's common in open marsh.
Flounder and black drum are secondary targets but worth fishing for. Flounder hold on the bottom in deeper holes and along channel edges; black drum root around shell ridges and oyster reefs. Both respond to live shrimp and cut mullet fished on the bottom.
Understanding Tides and Water Levels
Tides in Mandalay are subtle—the range is usually only a foot or so—but they control where fish are and how easy they are to reach. A rising tide pushes saltwater into the marsh, raising water levels and allowing fish to move into shallow areas where they feed. A falling tide drains the marsh, concentrating fish in the channels and deeper holes where they wait for the next tide cycle.
Wind also affects water levels. A strong south wind pushes water into the marsh and raises levels; a north wind pulls water out and lowers it. After a day of north wind, water can be so low that shallow-draft boats run aground. Check tide predictions and wind forecasts before you go, and be ready to move to deeper water if conditions change.
Regulations and Licensing Requirements
You need a valid Louisiana fishing license and a saltwater fishing permit. Both are available online through the Louisiana Department of Wildlife and Fisheries website or at tackle shops in Houma. Bag limits and size restrictions change by species and season, so check the current regulations before you fish. Redfish have a minimum size (usually 18 inches) and a daily bag limit; seatrout have similar restrictions. Flounder and black drum have their own rules.
The refuge itself has no special restrictions beyond state law, but the U.S. Fish and Wildlife Service manages it, so stay in designated fishing areas and follow posted signs. Hunting is allowed in certain seasons in parts of the refuge, so be aware of that if you're fishing during duck or deer season.
Tackle and Bait for Mandalay Conditions
Light to medium spinning tackle works well here. A 6.5 to 7-foot rod with 15 to 20-pound braid handles the shallow water and occasional larger redfish. Live shrimp is the most reliable bait; buy it fresh from a Houma tackle shop or bring it with you if you're traveling. Small mullet and pinfish also work. Soft plastics—3 to 4-inch paddle-tail shads in natural colors—are effective and less messy than live bait.
Bring more tackle than you think you'll need. The shallow water and shell ridges snag lures regularly. Polarized sunglasses help you spot fish in the clear water, especially on calm mornings. A push pole or electric trolling motor lets you move quietly through shallow water without spooking fish.
When to Fish and What to Expect
Spring (March through May) and fall (September through November) are the most comfortable and productive seasons. Water temperatures are moderate, fish are active, and the mosquitoes are manageable. Summer is hot and buggy; early morning trips before 10 a.m. are more bearable and often more productive because fish are active in cooler water. Winter can be slow, but calm days in December and January can be excellent.
Expect to see other boats, especially on weekends. The refuge is popular with locals and visiting anglers. Weekday mornings are quieter. Bring plenty of water, sunscreen, and bug spray. The marsh offers no shade, and the sun reflects off the water intensely. A wide-brimmed hat and long sleeves protect your skin and help you see better through polarized glasses.
Frequently Asked Questions
Do I need a guide to fish Mandalay?
No, but the refuge is large and navigation can be confusing if you're unfamiliar with it. A guide is helpful your first time, especially if you want to learn which areas hold fish in different seasons and tides. Many Houma guides fish Mandalay regularly and can show you productive spots.
What's the best tide for fishing?
Rising tides are usually most productive because fish move shallow to feed. The hour or two before high tide is often excellent. Falling tides concentrate fish in channels and holes, so they can be good too, but you'll cover less water and catch fewer fish overall.
Can I fish at night?
Yes, night fishing is allowed. Some anglers fish for catfish and other species after dark. Bring a good spotlight and navigation lights. The marsh is disorienting at night, so know your way out before you go in.
What if I run aground?
Soft bottom is common, and most boats can be poled or pushed off. Carry a push pole or have a trolling motor that can reverse. If you're truly stuck, call for help from another angler or a guide service. Cell service is spotty in the refuge, so let someone know where you're going before you leave.
Are there alligators?
Yes, alligators are present but rarely aggressive toward anglers in boats. Keep your distance and don't feed them. They're more active in warm months. Avoid wading in shallow water where visibility is poor.
