What You'll Find at Lake Penchant

Lake Penchant is a shallow, brackish impoundment in central Terrebonne Parish that holds catfish, largemouth bass, and occasional redfish. The lake sits roughly 20 miles south of Houma and covers around 1,200 acres of marsh-fringed water, with depths rarely exceeding 8 feet. The bottom is soft mud and silt, typical of coastal Louisiana, and the water stays turbid year-round—which actually works in your favor because these fish rely more on smell and vibration than sight.

The lake's primary draw is channel catfish and blue catfish, especially in spring and fall when water temperatures drop into the 60s and 70s. Largemouth bass are present but not abundant; they tend to concentrate around the few cypress stands and submerged timber on the north and west banks. Redfish show up during high tides and seasonal pushes, though they're less predictable than the catfish.

Key Takeaways

  • Lake Penchant holds catfish year-round, with the best action in spring and fall when water temperatures drop and fish move into shallower feeding zones.
  • Cut mullet, live shrimp, and chicken liver work best for catfish; bass respond to topwater plugs and soft plastics around cypress and fallen timber.
  • Launch from the public ramp on the south side near the levee road, or fish from the levee itself if you don't have a boat.
  • Water levels fluctuate with rainfall and tidal influence, so check conditions before you go and bring a push pole or shallow-draft boat.

When to Fish Lake Penchant

Spring (March through May) is the most reliable season. Water temperatures climb from the low 60s into the 70s, catfish move shallow to feed before spawning, and you can catch them consistently from dawn until mid-morning. Fall (September through November) mirrors spring—cooler water pushes fish into feeding mode, and the same shallow-water tactics work well.

Summer can be productive early and late in the day, but midday heat pushes catfish deeper and makes the shallow flats uncomfortable. Winter is slowest; catfish are lethargic and scattered, though you can still catch them if you're patient and fish the deepest holes near the center of the lake.

Tidal influence is weak at Lake Penchant compared to lower Terrebonne, but rainfall matters. Heavy rain raises water levels and can trigger feeding; prolonged drought lowers levels and concentrates fish in the remaining deeper pockets.

How to Fish for Catfish

Channel catfish and blue catfish dominate Lake Penchant, and both respond to the same baits and tactics. Cut mullet is the standard—fresh or frozen, cut into chunks roughly 2 to 3 inches. Live shrimp works well in spring when shrimp are abundant in the marsh. Chicken liver is reliable year-round and cheaper than mullet; it holds together better in current and stays on the hook longer when catfish are finicky.

Fish the shallow flats on the south and west banks during spring and fall, casting or drifting with a simple three-way rig: main line to a barrel swivel, one arm to a 12-inch leader and 1/0 to 3/0 circle hook, the other arm to a 1 to 2-ounce sinker. Circle hooks are standard for catfish because they hook themselves as they turn to swallow the bait—you rarely need to set hard. In summer, move to the deeper central basin and fish the bottom with the same rig, but wait longer between casts because fish are less aggressive.

Blue catfish can run larger than channels and prefer live bait or fresh-cut mullet over chicken liver. If you're targeting them specifically, use bigger chunks and heavier sinkers to keep bait on the bottom where blues hunt.

Bass and Redfish in Lake Penchant

Largemouth bass are present but scattered. The best spots are the cypress stands on the north bank and any submerged timber or fallen trees you can locate. Fish early morning or late afternoon with topwater plugs—the commotion attracts bass in shallow water. Soft plastics like 4-inch paddle-tail shads on 1/4-ounce jigs work well around structure, and you can cover water faster by casting and retrieving than by sitting still.

Redfish appear during spring tides and seasonal pushes, usually in the shallower eastern arms of the lake where marsh grass meets open water. They're not a primary target at Lake Penchant, but if you're sight-casting in 2 to 4 feet of water and spot a red, a live shrimp or small mullet will often draw a strike. Most redfish here are slot-sized (18 to 27 inches), so check current regulations before you keep one.

Access and Launch Information

The main public boat launch is on the south side of Lake Penchant, accessed via the levee road that runs east from Highway 1 near Montegut. The ramp is basic—concrete, no amenities—but it's free and usually in decent shape. Water depth at the ramp varies with rainfall; in dry periods, you may need a shallow-draft boat or a push pole to reach deeper water.

If you don't have a boat, you can fish from the levee itself along the south and west banks. The levee provides solid footing and good casting distance, and you can walk the length of it to find active fish. Bring a headlamp if you plan to fish early or late, and watch your footing on wet grass.

There is no fuel dock or tackle shop at the lake, so bring everything you need from Houma. The nearest services are in Montegut, about 10 miles north.

Gear and Tackle Recommendations

For catfish, a medium-heavy spinning rod (6 to 7 feet) with 15 to 20-pound braided line handles the shallow water and soft bottom well. Braided line cuts through the turbid water and gives you better feel for bottom contact and bites. A conventional reel works too and is traditional for catfishing, but spinning gear is simpler if you're new to the lake.

For bass, a medium spinning rod with 10 to 12-pound monofilament or braided line is standard. Topwater plugs, soft plastics, and small crankbaits all work; bring a variety because bass can be selective depending on water clarity and season.

Bring a push pole if you have a shallow-draft boat—Lake Penchant's soft bottom and shallow flats make poling easier and quieter than running the motor. A landing net is useful for catfish, and polarized sunglasses help you spot bass and redfish in the shallows, even in turbid water.

Regional Differences and What to Expect

Lake Penchant sits at the transition between freshwater marsh and brackish estuary, so salinity varies with season and rainfall. Spring and early summer bring fresher water; late summer and fall can be brackish enough to support redfish. This mix means you might catch catfish, bass, and reds in the same day, though catfish are the most consistent.

The lake is smaller and shallower than reservoirs in the western parishes, and the bottom is mud rather than rock or clay. That means your tackle needs to be heavier to stay in place, and your bait needs to be tougher because it sits in soft substrate longer. The water is always turbid, so bright colors and strong scents matter more than natural appearance.

Compared to Gulf coast systems farther south, Lake Penchant is protected from wind and tide, making it easier to fish in rough weather. It's also less crowded than popular spots near Houma, so you can often find solitude on weekdays.

Frequently Asked Questions

Do I need a boat to fish Lake Penchant?

No. The levee provides good access for bank fishing, and you can walk the south and west banks to find active fish. A boat lets you reach deeper water and cover more ground, but it's not required.

What's the best time of day to fish?

Early morning (sunrise to mid-morning) is most productive for catfish and bass. Catfish feed actively in low light, and bass respond well to topwater in the first few hours after sunrise. Evening (late afternoon through dusk) is also good, especially in summer.

Are there size or bag limits at Lake Penchant?

Yes. Louisiana Department of Wildlife and Fisheries sets limits for catfish, bass, and redfish. Catfish limits vary by species and size; largemouth bass have a 12-inch minimum and a daily bag limit; redfish must be between 18 and 27 inches. Check current regulations before you fish.

What should I do if the water level is very low?

Low water concentrates fish in the deeper central basin and near the launch ramp. Fish the bottom with heavier sinkers, and focus on the deepest holes you can find. If the ramp is too shallow for your boat, consider bank fishing from the levee instead.

Can I catch redfish consistently at Lake Penchant?

Redfish are present but not reliable. They show up during high tides and seasonal pushes, usually in spring and early summer. If redfish are your target, fish the shallower eastern arms where marsh grass meets open water, and use live shrimp or small mullet.
