Catfish Lake basics and what makes it different

Catfish Lake is a shallow, brackish impoundment in central Terrebonne Parish that holds channel catfish, blue catfish, and flathead catfish year-round. The lake sits roughly 15 miles south of Houma and covers around 3,000 acres of open water surrounded by marsh. Unlike the deeper bayou systems nearby, Catfish Lake is rarely deeper than 8 feet and often runs 3 to 5 feet in the main basin, which means water temperature swings fast with the seasons and weather.

The lake's brackish character — a mix of fresh and salt water — changes with rainfall and tidal influence. After heavy rains, salinity drops and catfish bite more aggressively. During dry spells or high tides, the water gets saltier and catfish move to deeper holes and channel edges. This variation matters more at Catfish Lake than at freshwater impoundments because it happens on a weekly or even daily basis.

Access is limited to a few public launch points and private camps. The main public ramp is at the Catfish Lake Wildlife Area, managed by the Louisiana Department of Wildlife and Fisheries. Parking is free, but the ramp can get crowded on weekends, especially during spring and fall when catfish are most active.

Key Takeaways

  • Catfish Lake holds channel, blue, and flathead catfish in shallow water that ranges from 3 to 8 feet deep, so you can fish it from a small boat or even a kayak.
  • Water salinity changes with rainfall and tides, so catfish bite best after rain when the lake freshens up.
  • The public launch at Catfish Lake Wildlife Area is free but fills up on weekends; arrive early or fish weekday mornings for better conditions.
  • Cut mullet, live shrimp, and chicken liver work year-round, but live bluegill and shiners produce bigger flatheads in spring and early summer.
  • Summer heat pushes catfish into deeper holes and channel edges; winter and spring offer the most consistent shallow-water action.

When to fish Catfish Lake for the best bite

Spring (March through May) is the peak season. Water temperatures climb into the 60s and 70s, catfish move shallow to spawn, and they feed hard before and after. Channel catfish bite all day, but the hour before sunset through midnight is most reliable. Blue catfish show up in deeper holes during the day but move to shallower flats at night.

Summer (June through August) is tougher. Daytime water temperatures exceed 85 degrees, and catfish retreat to the deepest holes — usually along old bayou channels and the lake's eastern edge where depth reaches 7 to 8 feet. Night fishing produces better results. Early morning (before sunrise) can be productive if you're on the water by 5 a.m.

Fall (September through November) brings a second strong bite as water cools and catfish move back to shallower feeding zones. September and early October are still warm, but by late October, water temperatures drop into the 60s and catfish become aggressive again. This is an excellent time for flatheads, which hunt actively in cooling water.

Winter (December through February) slows the bite but does not stop it. Catfish cluster in deeper holes and move less, so you need to fish the exact spots where they hold. Midday fishing can work better than night because the sun warms the shallows slightly. Channel catfish remain catchable; flatheads become harder to locate.

Baits, rigs, and tackle that work at Catfish Lake

Cut mullet is the standard bait and works every month. Use fresh mullet cut into 2- to 3-inch chunks, fished on a simple three-way rig with a 1- to 2-ounce sinker and a 18-inch leader to a 2/0 or 3/0 circle hook. Circle hooks reduce gut-hooked fish and are easier to remove. Cast near structure — fallen trees, channel edges, or deeper holes — and let the bait sit.

Live shrimp (when available) outperforms cut bait for channel catfish in spring and early summer. Fish them on a 1/0 or 2/0 circle hook under a small cork, or on the bottom with light weight. Shrimp are more expensive than mullet but the bite is often worth it.

Chicken liver is cheap, durable, and effective for channel catfish. It stays on the hook longer than cut bait and works well in current or when you're fishing multiple rods. Use a mesh bag or a small treble hook to keep it secure.

For flatheads, live bluegill or shiners (6 to 8 inches) are far superior to cut bait. Fish them on a 4/0 to 6/0 circle hook with minimal weight, allowing the baitfish to swim naturally. Flatheads hunt by sight and movement, so live bait matters more than scent. Fish at night, especially during spring and early summer when flatheads are most active.

Structure and where catfish hold

Catfish Lake's shallow bottom means structure is everything. Old bayou channels that cut through the lake hold catfish year-round because they offer depth and current. These channels are visible on a GPS map or a depth finder; they typically run 6 to 8 feet deep while the surrounding flat is 3 to 4 feet. Fish the channel edges rather than the center, where catfish hunt passing baitfish.

Fallen trees and root wads along the shoreline and in shallow water concentrate catfish, especially in spring and fall. These snags hold baitfish and provide shade. Fish tight to the wood; catfish will bite within inches of a submerged log.

The eastern shore, where the lake borders deeper bayou systems, is productive year-round. This area has more depth and tidal influence, so catfish use it as a refuge during summer heat and a feeding zone during cooler months.

Shallow flats (2 to 4 feet) produce best in spring and after rain when salinity drops. Channel catfish spread out across these flats to feed at night. Fish them from sunset through midnight, then move to deeper structure as dawn approaches.

Boat size and navigation

Catfish Lake is shallow enough for small boats. A 16- to 18-foot center console or open boat works well. Flat-bottomed skiffs and jon boats are ideal because they draw minimal water and let you access shallow flats and tight shoreline spots. A trolling motor is helpful for positioning without spooking fish, especially in spring when catfish are shallow.

Navigation is straightforward but requires attention. The lake has few hazards, but shallow water means you can run aground if you stray from the main basin. Use a GPS or a simple map to stay in deeper water when running between spots. The public ramp at Catfish Lake Wildlife Area is marked and easy to find; follow signs from Louisiana Highway 57.

Tides affect water level and current, especially in the eastern part of the lake where bayou influence is strongest. A rising tide pushes water into the lake and can improve the bite; a falling tide concentrates catfish in deeper holes. Check tide predictions for Terrebonne Parish before you go.

Regulations and what you need to know

Louisiana requires a freshwater fishing license for anyone 16 and older. You can purchase a one-day license online through the Louisiana Department of Wildlife and Fisheries website or at most bait shops in Houma. The cost varies but a one-day license is inexpensive compared to a full-year license.

Catfish have no size limit and no daily catch limit in Terrebonne Parish, so you can keep as many as you want. This makes Catfish Lake a good choice if you plan to keep fish for a fish fry. Channel catfish in the 2- to 5-pound range are common; blue catfish run larger, often 5 to 15 pounds. Flatheads can exceed 30 pounds but are less common.

The Catfish Lake Wildlife Area is open to the public during daylight hours. Camping and overnight stays are not permitted at the public ramp, but private camps and lodges in the area offer accommodations if you want to stay longer.

Getting there and what to bring

Catfish Lake is 15 miles south of Houma. From downtown Houma, take Louisiana Highway 57 south toward the coast. Follow signs for Catfish Lake Wildlife Area; the public ramp is well marked. The drive takes about 30 minutes from Houma.

Bring a cooler with ice, a headlamp or flashlight (especially for night fishing), insect repellent, and sunscreen. The marsh offers no shade, and mosquitoes are heavy in summer and fall. A basic first-aid kit is wise because the nearest hospital is in Houma. If you plan to fish at night, bring extra batteries and a backup light.

Bait shops near the ramp sell cut mullet, shrimp, and chicken liver. Prices are reasonable, but it's cheaper to buy bait in Houma before you drive out. Live baitfish (shiners and bluegill) are harder to find; call ahead to local shops or bring your own if you plan to fish for flatheads.

Frequently Asked Questions

Is Catfish Lake good for beginners?

Yes. The water is shallow and forgiving, catfish bite reliably in spring and fall, and you don't need expensive tackle. A simple rod, reel, and three-way rig with cut mullet will catch fish. The main challenge is finding the right spots, so fish near visible structure like fallen trees or channel edges.

Can I fish Catfish Lake from a kayak?

Yes, but with caution. The water is shallow enough, but the lake is open and exposed to wind. Afternoon winds can kick up quickly, making paddling difficult. Fish early morning or evening, stay in shallower areas near shore, and wear a life jacket. Catfish bite well at night, but night kayaking on an unfamiliar lake is risky.

What's the difference between channel catfish and blue catfish at Catfish Lake?

Channel catfish are smaller (usually 2 to 5 pounds), bite more readily on cut bait, and are more active during the day. Blue catfish run larger (5 to 20 pounds), prefer live bait or cut shad, and bite better at night. Both are good eating; channel catfish have milder flavor.

Do I need a guide to fish Catfish Lake?

No, but a guide can save time if you're unfamiliar with the lake. Local guides know the best structure, current conditions, and seasonal patterns. If you prefer to fish on your own, arrive early, fish near visible structure, and be patient — catfish are not hard to catch once you find them.

What's the best time of day to fish Catfish Lake?

Spring and fall: sunset through midnight for channel catfish; all night for flatheads. Summer: early morning (before sunrise) or night. Winter: midday when the sun warms shallow water. Night fishing is most consistent year-round, but you need a light and should fish with a partner.
