What You'll Find in Berwick Bay

Berwick Bay is a shallow, brackish estuary on Louisiana's central coast, about 90 miles south of Baton Rouge near Morgan City. The bay holds redfish, speckled trout, and flounder year-round, with seasonal runs of tarpon and Spanish mackerel. The water averages 4 to 6 feet deep across most of the bay, with scattered deeper holes and a maze of marsh grass that creates ideal habitat for sight-casting and wade fishing. The bay connects to the Gulf of Mexico through several passes, so salinity and fish behavior shift with tidal movement and seasonal freshwater inflow from the Atchafalaya River.

The bay's appeal lies in its accessibility and the sheer number of fish. You can reach productive water within minutes of the boat launch, and the shallow flats mean you can fish from a small skiff, kayak, or on foot. Redfish here run larger than in many other Louisiana bays—fish in the 6- to 8-pound range are common, and 10-pounders show up regularly. Speckled trout are plentiful but typically smaller, averaging 12 to 16 inches, though 20-inch fish are possible. The bay also draws serious anglers because it requires real technique: reading water, understanding tidal movement, and matching your approach to the season.

Key Takeaways

  • Redfish and speckled trout are the primary targets, with redfish running larger here than in many other Louisiana bays and available year-round.
  • The bay is shallow (4 to 6 feet average) with extensive marsh grass, making it ideal for sight-casting, wade fishing, and small-boat access.
  • Spring and fall are peak seasons for numbers and size, while summer heat pushes fish into deeper holes and early morning fishing becomes essential.
  • You need a Louisiana fishing license and a saltwater stamp; check current regulations for redfish bag limits and slot sizes before you fish.
  • Morgan City is the nearest town with boat launches, fuel, tackle shops, and lodging; plan for a 30- to 45-minute drive from Interstate 10.

Seasons and What to Expect

Spring (March through May) is the strongest season. Water temperatures climb into the 60s and 70s, and redfish move shallow to feed and spawn. Speckled trout congregate in the deeper holes and along channel edges. Sight-casting to redfish on the flats is productive, and topwater lures draw strikes throughout the day. Tides are moderate, and wind is often manageable. This is when visiting anglers catch the most fish and the largest redfish.

Summer (June through August) brings heat and low water clarity. Redfish retreat to deeper holes, channel edges, and the mouths of bayous where cooler water flows in. Speckled trout scatter and become harder to locate. Fish early—sunrise to mid-morning—before the sun drives them deeper. Live shrimp under a popping cork works well for trout; live mullet or cut bait draws redfish in the deeper holes. Afternoon fishing is slow. Thunderstorms are frequent and can close the bay quickly.

Fall (September through November) is the second-best season. Water cools, fish move back onto the flats, and both redfish and trout feed aggressively. Speckled trout often run larger in fall than spring. Tides can be strong, especially in September and October, so plan your fishing around slack water or incoming tide. Hurricane season peaks in September and October; check forecasts before committing to a trip.

Winter (December through February) is fishable but inconsistent. Cold fronts push water temperatures into the 40s and 50s, and fish move to the deepest holes and channel edges. Redfish are still present but less aggressive. Speckled trout fishing improves in late January and February as water stabilizes. Windy days are common, and boat access can be limited. This season suits anglers who know the bay well.

How to Reach Berwick Bay and Where to Launch

Berwick Bay is accessed from Morgan City, Louisiana, a working port town on the Atchafalaya River. From Interstate 10, take Exit 182 (La. 182 toward Morgan City) and follow it south for about 12 miles. The drive from I-10 takes 30 to 45 minutes depending on traffic and which launch you choose.

Morgan City Public Boat Launch is the primary access point. It sits on the Atchafalaya River near downtown Morgan City and has multiple lanes, fuel, and parking. The launch fee is typically $5 to $10 per day. From here, you motor south through the river channel into Berwick Bay proper—about 10 to 15 minutes depending on water level and current. The channel is well-marked and navigable year-round, though water levels drop in late summer.

Calumet Public Boat Launch is a smaller option on the east side of the bay, closer to some of the better flats. It has fewer amenities but less crowding. The launch fee is similar. From Calumet, you have more direct access to the shallow flats on the bay's eastern side.

Both launches have parking, and both are open dawn to dusk. Fuel is available at Morgan City marinas. Tackle shops in Morgan City stock live shrimp, mullet, and artificial lures; calling ahead ensures they have what you need, especially during peak season.

What Tackle and Lures Work Best

For redfish, sight-casting with topwater lures is the most exciting and productive method in spring and fall. Shallow-running plugs like MirrOlures, Rapala X-Raps, and Heddon Spooks work well. Soft plastics—4- to 6-inch paddle-tail shads in natural colors (mullet, shad, pearl)—are reliable year-round. Live mullet (4 to 8 inches) under a popping cork or free-lined along grass edges draws strikes. Live shrimp works but is less effective for larger redfish than mullet. Use 15- to 20-pound fluorocarbon leader and a 6- to 7-foot medium-power spinning rod.

For speckled trout, live shrimp under a popping cork is the standard. Cast near grass edges, channel drop-offs, and deeper holes. Small soft plastics (2 to 3 inches) on a 1/8-ounce jighead also work, especially in summer when trout are scattered. Topwater lures produce in spring and fall, particularly early morning. Use 12- to 15-pound fluorocarbon leader and a 6-foot light-to-medium spinning rod.

Flounder are present but not the primary target. They hold in deeper holes and channel edges. Live mullet or shrimp on a 1/4-ounce jighead works. Fish the deeper water (6 to 8 feet) along the bay's edges and in the Atchafalaya River channel.

Bring multiple rod setups if you can. Conditions change throughout the day, and switching between topwater, soft plastics, and live bait keeps you fishing effectively. Polarized sunglasses are essential for sight-casting on the flats.

Regulations and Licensing

You need a Louisiana fishing license and a saltwater stamp. Both are available online through the Louisiana Department of Wildlife and Fisheries (LDWF) website, at tackle shops in Morgan City, or at the boat launches. A three-day tourist license costs less than a full-year license and is a good option if you're visiting for a short trip.

Redfish have a daily bag limit of three fish per person. The slot size varies by season and management zone; check the current LDWF regulations before you fish because slot limits change. Generally, redfish between 18 and 27 inches are legal, but this can shift. Fish outside the slot are released.

Speckled trout have a daily bag limit of 25 fish per person with no size restriction, though most anglers practice catch-and-release on smaller fish. Flounder have a 10-fish daily bag limit and must be at least 12 inches. Tarpon and Spanish mackerel have their own regulations; check LDWF before targeting them.

Regulations are enforced by Louisiana Wildlife and Fisheries officers. Violations carry fines and can result in loss of fishing privileges. Keep your license on you while fishing.

Where to Stay and What to Bring

Morgan City has several motels, including budget chains and locally-owned options. Rooms range widely in price depending on season and day of week. Spring and fall weekends book up, so reserve ahead. Some motels cater to fishing trips and can arrange guide services or provide fishing reports.

Restaurants in Morgan City serve seafood and casual fare. Grocery stores stock snacks, drinks, and basic supplies. The town is small but functional for a fishing trip.

Bring sunscreen, a hat, and long sleeves—the sun reflects off the water and burns quickly. Bring more water than you think you'll need. Mosquitoes are present year-round, especially in summer and fall; insect repellent helps. Waders are useful for wade fishing the flats, though many anglers fish from boats. A cooler with ice keeps your catch fresh and your drinks cold. Binoculars help spot redfish tails on the flats from a distance.

Tides, Weather, and Timing

Berwick Bay is tidally influenced, with tides typically ranging 1 to 2 feet. Incoming tide pushes fish onto the flats and into the marsh grass; outgoing tide concentrates them in deeper holes and channels. The best fishing often occurs during the first two hours of incoming tide and the last two hours of outgoing tide. Slack water (the brief period between tides) can be slow.

Wind direction matters. A south or southeast wind pushes water into the bay and raises water levels, which is good for flats fishing. A north or northwest wind lowers water levels and can make shallow areas unfishable. Check the forecast before you launch.

Freshwater inflow from the Atchafalaya River affects salinity and fish behavior. High river levels (usually in spring) push fresh water into the bay, which can temporarily scatter fish or push them to the bay's edges where saltier water remains. This is temporary; fish adjust within a day or two.

Frequently Asked Questions

Can I wade fish in Berwick Bay?

Yes. Much of the bay is 3 to 5 feet deep, making it ideal for wading. Wear waders or water shoes because the bottom is soft mud and grass. Wade slowly and watch for deeper holes. Sight-casting to redfish while wading is productive in spring and fall. Early morning provides the best light for spotting fish.

What's the best time of day to fish?

Early morning (sunrise to 10 a.m.) is most productive year-round. Fish feed actively in low light and cooler water. Summer fishing is best from sunrise to mid-morning; afternoon fishing is slow. Fall and spring allow all-day fishing, though morning is still strongest.

Do I need a guide?

No, but a guide is helpful if you're unfamiliar with the bay. Guides know the current conditions, where fish are holding, and how to read the water. Morgan City has several guide services; expect to pay $300 to $500 per day for a full-day trip. If you fish on your own, arrive early to scout, talk to other anglers at the launch, and ask tackle shop staff where fish are biting.

What if the water is too murky to sight-cast?

Live bait becomes your primary method. Fish live shrimp or mullet under a popping cork in the deeper holes and along channel edges. Soft plastics on a jighead also work in murky water. Topwater lures can draw strikes even when visibility is poor because fish respond to vibration and sound.

Is Berwick Bay safe to fish alone?

Yes, but use common sense. Tell someone where you're going and when you'll return. Carry a charged cell phone and a personal flotation device. The bay is busy with commercial traffic, especially near the river channel; stay alert and keep your boat visible. Weather can change quickly; check the forecast and leave early if storms approach.
