What Bayou Caddy Offers

Bayou Caddy is a narrow, shallow tidal waterway in Hancock County on Mississippi's Gulf Coast, roughly 40 miles south of the state capital. The bayou connects to the Gulf of Mexico through a series of passes and marshes, making it a brackish system where freshwater and saltwater mix. The water is typically stained dark brown from tannins, and depths range from 2 to 8 feet in the main channel, with much shallower areas in the surrounding marsh.

The bayou is known for redfish, spotted seatrout, and flounder in the shallower sections, with tarpon and large catfish present seasonally. The surrounding marsh and mangrove-like vegetation create a maze-like environment that rewards anglers who know the tides and can navigate tight quarters. Access is limited and requires a boat, and the area sees far fewer anglers than the more famous Mississippi Sound fisheries to the east.

Key Takeaways

  • Bayou Caddy holds redfish and spotted seatrout year-round, with the best fishing during spring and fall when water temperatures are moderate.
  • You will need a shallow-draft boat—a skiff or flats boat under 18 feet works best—because much of the bayou is 2 to 4 feet deep.
  • Tides control where fish hold and how accessible different sections are, so checking tide tables before you go is essential.
  • The bayou is accessible only by private boat; there are no public boat launches directly on Bayou Caddy itself, though nearby ramps serve the area.
  • A Mississippi fishing license is required, and saltwater endorsement rules apply because the bayou is tidal and brackish.

When to Fish Bayou Caddy

Spring (March through May) and fall (September through November) are the most productive seasons. During spring, redfish move into the shallows to feed after winter, and water temperatures in the 60s to 70s bring spotted seatrout into the bayou. Fall sees similar conditions as water cools from summer heat, and both species feed aggressively before winter.

Summer (June through August) is possible but challenging. Water temperatures climb into the 80s and 90s, and fish move deeper or into the marsh during the heat of the day. Early morning and late evening trips are more productive than midday. Winter (December through February) slows the bite considerably, though redfish remain in the bayou and can be caught on mild days when water temperatures stay above 50 degrees.

Species and What to Expect

Redfish are the primary target. They patrol the shallow flats and marsh edges year-round, feeding on crustaceans and small fish. Reds in Bayou Caddy typically run 18 to 28 inches, though larger fish are present. They are sight-fishing opportunities on calm days when you can spot tails in the shallows.

Spotted seatrout (speckled trout) school in deeper holes and channel edges, especially near structure like fallen trees or oyster beds. They respond well to live shrimp and soft plastics. Fish in the 15 to 22-inch range are common, with occasional larger fish in the deeper sections.

Flounder hold on the bottom in 4 to 8 feet of water, particularly in the main channel and near the passes. They are less abundant than reds or trout but present year-round. Live mullet or large shrimp work best.

Tarpon move into the bayou during summer months (June through August), typically on high tides when they push into the shallows. These are large, powerful fish that require heavy tackle and are more of a specialty target than a reliable fishery.

Boat Requirements and Navigation

A shallow-draft boat is mandatory. Skiffs and flats boats under 18 feet with a draft of 12 inches or less are ideal. The main channel holds 4 to 8 feet of water, but much of the productive fishing happens in 2 to 4 feet, and the marsh edges drop to 1 to 2 feet. A poling platform or push pole is valuable for sight-fishing the shallows without spooking fish.

Navigation requires attention to tide and local knowledge. The bayou has no marked channel buoys in many sections, and shallow areas shift with tides and seasonal water levels. A GPS unit with detailed maps of the area is helpful, but a local guide or detailed knowledge of the system is safer, especially on your first trip. Tides swing 2 to 3 feet, and low tide can leave you stranded in sections that are fishable at high tide.

Regulations and Licensing

A valid Mississippi fishing license is required. Because Bayou Caddy is tidal and brackish, saltwater endorsement rules apply. Redfish have a 18-inch minimum and 27-inch maximum length limit, with a daily bag limit of three fish per person. Spotted seatrout have an 12-inch minimum and 19-inch maximum, with a five-fish daily limit. Flounder have a 14-inch minimum with a ten-fish daily limit.

Tarpon are catch-and-release only in Mississippi waters. Check current regulations with the Mississippi Department of Marine Resources before you go, as rules can change. Licenses are sold online, at sporting goods stores, and at many bait shops in the area.

Access and Nearby Services

There is no public boat launch directly on Bayou Caddy. The nearest public ramps are at Waveland (about 15 miles north) and at various marinas in the Bay St. Louis area (about 20 miles east). Both require a short run to reach the bayou, but they are the standard access points for anglers targeting this water.

Bait and tackle shops in Waveland and Bay St. Louis stock live shrimp, mullet, and frozen bait. They can also provide current information on water conditions and recent catches. Fuel and supplies are available in both towns. The bayou itself has no facilities—plan to bring water, snacks, and sun protection for a full day on the water.

Tackle and Technique

For redfish and trout, medium spinning tackle (6 to 7-foot rods with 15 to 20-pound braided line) is standard. Live shrimp under a popping cork is effective for trout in deeper water. For sight-fishing redfish in the shallows, soft plastic baits (3 to 4-inch paddle-tail or shrimp imitations) on light jig heads work well and allow you to cover more water quietly.

Flounder fishing calls for heavier tackle and live bait fished on the bottom. A 6 to 7-foot medium-heavy rod with 20-pound line and a 2 to 3-ounce sinker keeps bait in the strike zone. Tarpon require heavy tackle (8 to 9-foot rods, 30 to 50-pound line) and large live mullet or mackerel. Most anglers targeting tarpon use wire leaders to prevent bite-offs.

Frequently Asked Questions

Do I need a guide to fish Bayou Caddy?

A guide is not required but is valuable on your first trip. The bayou's shallow, unmarked sections and tide-dependent navigation make local knowledge useful. Many guides based in Waveland and Bay St. Louis fish Bayou Caddy regularly and can teach you the tides, structure, and sight-fishing techniques specific to the water.

What is the best tide for fishing Bayou Caddy?

Rising and high tides are generally most productive because they push fish into the shallows and open up more water to fish. Low tide can strand you in shallow areas and concentrate fish in the main channel, which can be good but limits your options. Plan your trip around the tide table for the day you want to fish.

Can I fish Bayou Caddy in winter?

Yes, but the bite is slower. Redfish remain in the bayou and can be caught on mild days when water temperatures stay above 50 degrees. Spotted seatrout move deeper and are less active. Winter trips are best on calm, sunny days when water warms slightly.

What size boat do I need?

A boat under 18 feet with a shallow draft (12 inches or less) is ideal. Larger boats with deeper drafts can fish the main channel but cannot access the productive shallow flats and marsh edges where most redfish are found.

Is Bayou Caddy crowded?

No. Bayou Caddy sees far fewer anglers than the more famous Mississippi Sound fisheries. The shallow water, limited access, and need for a shallow-draft boat keep pressure light, which means less competition and more fish for those who make the trip.
