What Colyell Bay offers and how to fish it

Colyell Bay sits in Plaquemines Parish at the southeast tip of Louisiana, where the Mississippi River meets the Gulf of Mexico. The bay is a shallow, brackish system that holds redfish, spotted seatrout, and flounder year-round, with tarpon and permit moving through in warmer months. Access is limited — there are no public boat launches directly on the bay itself, and most anglers reach it by launching from nearby communities like Buras or Venice and running south through the river delta.

The bay's shallow flats and marsh edges make it best suited to shallow-draft boats: skiffs under 18 feet, kayaks, and poling skiffs. Wading is possible in some areas during lower tides, but the bottom is soft mud and the water clarity varies with river flow. Most productive fishing happens during slack tide or incoming water, when fish move onto the flats to feed.

Key Takeaways

  • Colyell Bay holds redfish and spotted seatrout year-round, with tarpon present from May through September in deeper channels.
  • Launch from Buras or Venice and run south through the Mississippi River delta; no public ramps exist on the bay itself.
  • A shallow-draft skiff or kayak is essential — the bay averages 2 to 4 feet deep with soft mud bottom.
  • Louisiana saltwater fishing license is required; check current regulations for redfish and seatrout bag limits before you go.
  • Water clarity and fish location shift with Mississippi River discharge, so local guides or recent reports are worth the investment.

Seasons and what fish are present

Redfish are the primary target year-round. Fall and winter (October through February) bring the most stable conditions and the largest concentrations of reds on the shallow flats. Water temperatures drop, fish move predictably, and the reduced river flow clears the water. Spring (March through May) sees redfish scatter as water warms, but tarpon begin arriving in the deeper channels and along the outside edges of the bay.

Summer (June through August) is hot and the river discharge is often high, which pushes fresh water into the bay and makes sight-fishing difficult. Tarpon and permit are present but require patience and local knowledge. Spotted seatrout are present all year but are most abundant in fall and winter. Flounder move through in spring and fall migrations, concentrating near deeper holes and channel edges.

Access and launch points

Buras, located about 80 miles south of New Orleans via Highway 1, has public boat launches at the Buras Marina and the Plaquemines Parish Recreation Complex. Both are on the Mississippi River, not directly on Colyell Bay, but they are the closest reliable public access. From Buras, the run to Colyell Bay is roughly 15 to 20 minutes by skiff, heading south and east through the river delta.

Venice, another 30 miles further south on Highway 1, also has public launches and is even closer to the bay's eastern approaches. The Venice Marina and nearby facilities cater to both recreational and commercial traffic. From either launch point, you will be running through active river channels and past commercial fishing operations — stay alert for tug traffic and keep to marked channels.

Private guides operate out of both Buras and Venice and can save time and frustration, especially if you are unfamiliar with the delta's maze of channels and the bay's shifting conditions. A guide also knows current water levels, recent fish movements, and which areas are productive on the day you are fishing.

Regulations and licensing

Louisiana requires a saltwater fishing license 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 bait and tackle shops in Buras and Venice. The license is inexpensive and covers all saltwater species in state waters.

Redfish have a daily bag limit of three fish per person, with a 18-inch minimum length. Spotted seatrout limit is 25 fish per person, with a 12-inch minimum. Flounder is 10 fish per person at 12 inches minimum. Tarpon and permit are catch-and-release only — they cannot be kept. Check the current Louisiana fishing guide before you leave, as regulations change and seasonal closures can affect what you can target.

Tackle and techniques for Colyell Bay

Redfish in the shallows respond to live bait and artificial lures. Live mullet, menhaden, and shrimp work well when drifted or cast near marsh edges and grass beds. For artificials, soft plastics in natural colors — 3 to 4-inch paddle-tail shads in pearl, chartreuse, or natural patterns — are effective. Topwater plugs can produce explosive strikes during early morning and late afternoon, especially in fall and winter.

Spotted seatrout prefer smaller baits and lures. Live shrimp under a popping cork is a classic approach. Soft plastics in the 2 to 3-inch range work well, and many anglers use a jig head with a shrimp or small shad. Tarpon in the channels require heavier tackle — 8 to 10-weight fly rods or conventional outfits rated for 20 to 30-pound line. Live mullet or large shiners are standard, cast near deeper holes and channel bends.

Sight-fishing is possible when water clarity allows. Polarized sunglasses and a poling platform or elevated position in the boat help you spot fish on the flats. Early morning and late afternoon offer the best light for spotting. Overcast days can be productive too, since fish are less spooky in lower light.

Conditions and what to bring

Colyell Bay is exposed to Gulf weather and can get rough quickly. Check the forecast before launching, especially from June through November when tropical systems are possible. The bay itself is shallow and protected compared to open Gulf waters, but the run through the delta can be choppy if wind is up. Bring extra fuel — the nearest gas is in Buras or Venice, and running out in the delta is a serious problem.

Sun protection is essential. The water reflects intensely and there is no shade on the flats. Bring sunscreen, a hat, and long sleeves if you can tolerate them. Mosquitoes are present year-round but are worst in summer and fall — insect repellent is worth the space in your bag. Bring fresh water to drink and a small cooler with ice. The nearest food and supplies are in Buras or Venice, so plan accordingly.

Tides in the delta are complex and driven partly by river discharge as well as Gulf tides. Slack water and incoming tide are usually best for fishing. Check tide tables for Port Fourchon or Venice before you go, but understand that river flow can override normal tidal patterns. A local guide or recent fishing reports will give you the most accurate picture of current conditions.

Getting there and planning your trip

Colyell Bay is a 90-minute to two-hour drive from New Orleans depending on which launch you choose. Highway 1 south is the only road access to Buras and Venice. The drive is long and the road is narrow in places, so plan to leave early if you want to fish at first light. Gas stations and food are available in Buras and Venice, but options are limited compared to larger towns.

Most anglers fish Colyell Bay as a day trip, launching at dawn and returning by late afternoon. Overnight lodging exists in Buras and Venice but is basic — plan ahead if you want a room. Many anglers stay in Houma or other towns further north and make the drive south. The bay is fishable year-round, but fall and winter offer the most stable conditions and the clearest water.

Frequently Asked Questions

Do I need a guide to fish Colyell Bay?

No, but a guide is valuable if you are unfamiliar with the delta's channels or if water conditions are poor. The bay itself is not large, but reaching it requires navigating the Mississippi River delta, which can be confusing. A guide also knows which areas are productive on the day you fish and can save you time and frustration.

What is the best time of year to fish Colyell Bay?

Fall and winter (October through February) offer the most stable conditions, clearest water, and largest concentrations of redfish. Spring is good for redfish and the arrival of tarpon. Summer can be productive but is hot and the river discharge often clouds the water, making sight-fishing difficult.

Can I wade fish in Colyell Bay?

Wading is possible in some shallow areas during low tide, but the bottom is soft mud and can be difficult to walk. Most anglers fish from a boat or kayak. If you wade, wear wading boots with good grip and be aware that the bottom can shift. Always wear a life jacket and fish with a partner.

What should I do if I get lost in the delta?

Stay calm and use your GPS or map to identify your location. Mark your launch point in your GPS before you leave. If you have cell service, call the launch facility or a local guide service. The delta channels can look similar, so marking waypoints as you travel helps you retrace your route. Always carry extra fuel and a charged phone.

Are there any seasonal closures I should know about?

Check the current Louisiana fishing guide for any seasonal closures or special regulations. Redfish and seatrout seasons are generally open year-round, but bag limits and size restrictions can change. Some areas may have temporary closures due to environmental conditions or research. Contact the Louisiana Department of Wildlife and Fisheries if you have questions about current rules.
