What You'll Find at Haymark Cove

Haymark Cove is a shallow, protected estuary in Terrebonne Parish that holds redfish, spotted seatrout, and flounder in the grass flats and deeper channels. The cove sits roughly 40 miles south of Houma and is accessible by boat from several launch points along Bayou Terrebonne. Water depths range from 2 to 8 feet across most of the cove, making it suited to poling skiffs, shallow-draft boats, and kayaks rather than larger center-console vessels.

The cove's appeal lies in its consistency: it holds fish year-round, though fall and spring bring the most predictable action. The shallow grass beds attract feeding redfish during low light, and the slightly deeper channels near the cove's mouth hold seatrout when the tide pushes water through. Haymark is also less crowded than some of the more famous Terrebonne Parish flats, which means you can often find fish without competing for space.

Key Takeaways

  • Haymark Cove holds redfish and spotted seatrout in shallow grass flats and channels, with water depths between 2 and 8 feet.
  • Launch from Cocodrie Marina, Terrebonne Parish boat ramps, or private access points along Bayou Terrebonne, depending on which part of the cove you want to fish.
  • Fall (September through November) and spring (March through May) are the most reliable seasons, though fish are present year-round.
  • Louisiana saltwater fishing license is required; check current redfish and seatrout bag limits and size restrictions before you go.
  • Tides and wind direction matter more than time of day—low tide concentrates fish in channels, and calm mornings allow sight-casting on the flats.

Seasons and Best Times to Fish

Fall runs from September through November and is the strongest season at Haymark Cove. Redfish move into the shallow flats to feed as water temperatures drop, and seatrout congregate in the deeper channels and along structure. Early morning and late afternoon are most productive, but the entire day can hold fish if the wind stays down. Water clarity is usually good in fall, which makes sight-casting possible if you pole the flats.

Spring (March through May) is the second-best window. Redfish spawn in the deeper channels and around the cove's mouth, and seatrout feed heavily before summer heat pushes them into deeper water. Water temperatures climb steadily, and by late May the bite can slow as fish move to cooler refuges. Summer (June through August) is slow and hot; fish are present but scattered, and midday heat makes sight-casting difficult.

Winter (December through February) is unpredictable. Cold fronts can shut down the bite for days, but between fronts the fishing can be excellent. Redfish and seatrout move into the deepest parts of the cove and the channels leading to it. If you fish winter, plan for shorter windows of opportunity and be prepared to move if the weather turns.

How to Reach Haymark Cove and Where to Launch

Cocodrie Marina is the most direct launch point. It sits at the end of Louisiana Highway 1, roughly 40 miles south of Houma, and offers fuel, tackle, and boat launch services. From Cocodrie, Haymark Cove is a 15- to 20-minute run south through Bayou Terrebonne. The marina charges a launch fee (amounts vary by season and vessel size) and has parking for trailers.

Terrebonne Parish also maintains public boat ramps along Bayou Terrebonne between Houma and Cocodrie. These ramps are free or low-cost and provide access to the bayou system, though you will have a longer run to reach Haymark Cove itself. Check with the Terrebonne Parish Parks and Recreation Department for current ramp locations and conditions, as some close seasonally or after storms.

Private access through hunting and fishing camps is another option if you know someone with property in the area. Many camps have private docks and are willing to let guests launch for a fee. This can save time and fuel if you find a camp close to the cove.

What Species to Target and Regulations

Redfish (red drum) are the primary target. They range from 18 inches to over 30 pounds and respond to live mullet, live shrimp, and topwater plugs. The current Louisiana redfish bag limit is three fish per person per day, with a 16-inch minimum size. Slot limits (which restrict the size of fish you can keep) vary by area and change periodically, so check the current Louisiana Department of Wildlife and Fisheries regulations before you fish.

Spotted seatrout are abundant and willing. They average 12 to 18 inches but can reach 25 pounds. Seatrout bite on small shrimp, soft plastics, and live baitfish. The current bag limit is 25 fish per person per day with a 12-inch minimum, though this can change. Flounder are also present in the deeper channels and around structure; they take live shrimp and small mullet.

A Louisiana saltwater fishing license is required for anyone 16 and older. You can purchase a three-day, seven-day, or annual license through the Louisiana Department of Wildlife and Fisheries website or at most tackle shops and marinas. Licenses are inexpensive and can be obtained online before you arrive. Always verify current bag limits and size restrictions on the LDWF website, as regulations are updated regularly.

Tactics and What to Bring

Sight-casting on the flats is the most effective approach when conditions allow. Use a shallow-draft skiff or kayak, pole slowly along the grass beds, and watch for tailing redfish or cruising seatrout. Cast ahead of the fish and retrieve slowly. Early morning with calm wind and clear water gives you the best visibility. Polarized sunglasses are essential—they cut glare and let you spot fish before they see you.

If sight-casting is not possible (cloudy water, rough conditions), work the channels and deeper edges with live bait. Anchor or drift and cast live shrimp or mullet near structure, drop-offs, and current breaks. This approach is less exciting than sight-casting but often more productive when water clarity is poor.

Bring light to medium spinning tackle (6 to 8-pound test) for seatrout and light redfish, and heavier gear (10 to 12-pound test) if you expect larger redfish. Topwater plugs, soft plastics in natural colors, and live shrimp are the core lures. Bring extra tackle because the shallow grass flats can be snaggy. A push pole, wading boots, and a net round out the essentials.

Tides, Wind, and Weather Patterns

Tides matter more at Haymark Cove than they do in some other Louisiana fisheries. Low tide concentrates redfish and seatrout in the deeper channels and holes, making them easier to find and target. High tide spreads fish across the flats, which can make sight-casting more difficult but also means fish are more dispersed and less pressured. Plan your tide around your fishing style: low tide for channel fishing, high tide for flats work if you can spot fish.

Wind direction affects water clarity and fish behavior. A south or southeast wind pushes water into the cove and can improve clarity; a north wind can muddy the water and push fish deeper. Calm mornings are ideal for sight-casting regardless of wind direction. Avoid fishing during strong fronts or sustained high winds—the bite shuts down and the water becomes too rough for small boats.

Haymark Cove is exposed to the Gulf of Mexico, so weather can change quickly. Check the forecast before you leave, and be prepared to head back to the marina if conditions deteriorate. Summer afternoon thunderstorms are common; plan to be off the water by mid-afternoon during the warm months.

Lodging and Services Near Haymark Cove

Cocodrie is the closest town to Haymark Cove and offers a few small motels, fishing camps, and restaurants. Lodging is basic but functional, and most places cater to anglers. Book ahead during fall and spring when the fishing is best, as rooms fill quickly. Fuel, ice, and tackle are available at Cocodrie Marina and nearby shops.

Houma, about 40 miles north, is a larger town with more lodging options, restaurants, and services. The drive from Houma to Cocodrie takes roughly 45 minutes to an hour, so staying in Houma is an option if you prefer more amenities. Many anglers split the difference and stay in Cocodrie for convenience, accepting the smaller selection in exchange for a shorter boat ride.

Frequently Asked Questions

Do I need a guide to fish Haymark Cove?

No, but a guide can be valuable if you are unfamiliar with the area or want to learn the flats quickly. Local guides know the tides, seasonal patterns, and productive spots. If you decide to hire one, book through Cocodrie Marina or ask at local tackle shops for recommendations.

What's the best time of day to fish Haymark Cove?

Early morning and late afternoon are most productive, especially during fall and spring. Tides and wind matter more than the clock, though. A low tide in the middle of the day can be better than a high tide at dawn if it concentrates fish in the channels.

Can I fish Haymark Cove from a kayak?

Yes. Kayaks are ideal for the shallow flats and allow you to approach fish quietly. Bring a PFD, a small tackle box, and a way to secure your kayak. Be aware that kayaks offer no protection from weather, so stay close to shore and watch the forecast.

What should I do if I catch a fish that's under the size limit?

Release it immediately and gently. Handle it by the lower lip (for redfish) or behind the gills, keep your hands wet, and return it to the water quickly. Avoid squeezing the fish or letting it flop on the deck.

Is Haymark Cove affected by saltwater intrusion or freshwater runoff?

Yes. Heavy rainfall and river discharge can lower salinity and muddy the water, which can slow the bite. Drought or dry periods can increase salinity. These cycles are normal in coastal Louisiana and affect fish behavior, but they do not make the cove unfishable—you may just need to adjust your tactics or timing.
