What to expect at Iatt Lake

Iatt Lake is a shallow, 400-acre impoundment in Morehouse Parish in northeast Louisiana, roughly 20 miles south of Bastrop. The lake sits in flat terrain typical of the Mississippi River Delta region, with cypress trees, tupelo, and marsh vegetation fringing most of the shoreline. Water depth rarely exceeds 8 to 10 feet, and much of the lake is shallower — a characteristic that makes it productive for largemouth bass and catfish but requires careful navigation, especially during low-water periods in late summer and fall.

The lake is managed by the Louisiana Department of Wildlife and Fisheries and is open to the public. Access is limited to a few boat launch points, and the lake draws a steady but not crowded crowd of local anglers. Because of its shallow profile and vegetation, Iatt Lake fishes best in spring and early summer, when water levels are higher and bass move into the shallows to spawn and feed.

Key Takeaways

  • Iatt Lake is a shallow, 400-acre lake in Morehouse Parish best fished in spring and early summer when water levels are highest and bass are active in shallow cover.
  • Largemouth bass and channel catfish are the primary species; bass average 2 to 4 pounds, and catfish are caught year-round on cut bait and live shiners.
  • A Louisiana fishing license is required for all anglers 16 and older, and current regulations allow five largemouth bass per day with a 12-inch minimum length.
  • Boat access is available at the public launch on the north side of the lake; the ramp is maintained but can be soft during wet weather.
  • Shallow-draft boats, kayaks, and canoes work best because much of the lake is 4 to 6 feet deep, and submerged stumps and cypress knees create navigation hazards.

Species and seasonal patterns

Largemouth bass are the primary draw at Iatt Lake. Fish typically range from 2 to 4 pounds, with occasional 5-pounders caught in spring. Bass spawn in March and April in the shallowest bays and along the cypress-lined margins. During this window, they are aggressive and respond well to topwater lures, soft plastics worked slowly through shallow cover, and small crankbaits. May and June remain productive as fish move slightly deeper but stay in vegetation and around structure.

Channel catfish are present year-round and provide a secondary fishery. They are caught most consistently from June through September on cut bait — shad, mullet, or chicken liver — fished on the bottom in 4 to 6 feet of water. Live shiners also work well. Catfish average 2 to 5 pounds, though larger fish are possible. Night fishing is common and often more productive than daytime.

Summer heat (July and August) slows bass activity significantly. Fish move to deeper holes and thicker cover, making them harder to locate. Many anglers shift focus to catfish during this period or fish early morning and late evening. By fall, water levels often drop noticeably, concentrating fish in the deeper central basin and around remaining vegetation. Winter fishing is slow; most anglers target catfish on the bottom.

Regulations and licensing

A Louisiana fishing license is required for all anglers 16 years old and older. Licenses are available online through the Louisiana Department of Wildlife and Fisheries website, at sporting goods retailers, and at some bait shops. A three-day tourist license is available for visitors and costs less than an annual resident license.

Current regulations for largemouth bass at Iatt Lake allow five fish per day with a 12-inch minimum length. Catfish have no daily limit and no minimum size. Regulations can change, so check the current Louisiana fishing guide before you go. Trotlines and juglines are permitted for catfish in Louisiana but are subject to specific rules about number and placement; review the current regulations if you plan to use them.

Access and boat launch

Public boat access is available at a single launch on the north side of Iatt Lake, maintained by the Louisiana Department of Wildlife and Fisheries. The ramp is concrete and accommodates single-axle and tandem trailers. During wet weather, the approach can become soft or muddy, so a high-clearance vehicle is helpful. There is no fee to launch.

Parking is limited to a small lot adjacent to the ramp. The area has no amenities — no restrooms, no fuel dock, no tackle shop. The nearest town with services is Bastrop, about 20 miles north. Plan to bring fuel, water, and supplies with you. Cell service can be spotty in the area, so do not rely on it for navigation or emergencies.

Boat type and navigation

Iatt Lake's shallow depth and submerged structure demand careful boat selection and operation. A shallow-draft aluminum boat, jon boat, or bass boat with a trolling motor is ideal. Kayaks and canoes work well for anglers willing to paddle and fish slowly. Avoid deep-V hulls and large center-console boats, which will run aground or strike stumps.

Submerged cypress knees, stumps, and fallen trees are scattered throughout the lake. These hazards are most dangerous in the shallower bays and along the margins. Operate at idle speed in unfamiliar areas, and watch the water surface for signs of structure. A depth finder helps, but it does not catch everything. During low-water periods (late summer and fall), navigation becomes more difficult; many anglers avoid the lake during these months.

Tackle and technique for bass

Spring bass fishing at Iatt Lake responds well to topwater plugs, especially early and late in the day. Spinnerbaits and soft plastics — 4-inch worms and creature baits — worked slowly through shallow cover produce consistently. Crankbaits that reach 3 to 5 feet work in slightly deeper areas. Cast to the edges of cypress stands, fallen trees, and vegetation mats. Patience and a slow retrieve often outperform aggressive fishing.

In summer and fall, switch to darker colors and fish deeper structure. Soft plastics rigged Texas-style on 3/16- to 1/4-ounce weights allow you to fish heavy cover without constant snagging. A 6- to 7-foot medium-power rod with 12- to 15-pound monofilament or braided line is standard. Fluorocarbon leaders can help in clear water, though Iatt Lake is typically stained to slightly murky.

Catfish fishing and night angling

Catfish are most reliably caught on the bottom in 4 to 6 feet of water, away from the thickest vegetation. Cut shad or mullet, chicken liver, and stink baits all work. Use a simple three-way rig or a slip sinker rig with a 2/0 to 4/0 circle hook. Cast out, set the rod in a holder, and wait. Catfish often bite within 15 to 30 minutes of bait hitting bottom.

Night fishing for catfish is popular and often more productive than day fishing. Bring a headlamp, a cooler, and patience. Many anglers fish two or three rods simultaneously, which is legal in Louisiana. The deeper central basin and areas near the old channel are good night spots. Catfish bite throughout the night, though activity often peaks in the first two hours after dark and again near dawn.

When to fish and what to bring

Spring (March through May) is the best time to fish Iatt Lake. Water levels are high, bass are active, and weather is mild. Early morning and late afternoon are most productive. Summer requires early starts and patience; many anglers fish 5 a.m. to 9 a.m. and then leave as heat builds. Fall can be good in September and early October, but water levels drop and navigation becomes tricky. Winter is slow.

Bring sunscreen, insect repellent (mosquitoes and biting flies are heavy in warm months), a first-aid kit, and plenty of water. The lake is remote, and help is not nearby. A fully charged phone, a map or GPS unit, and a basic tool kit are wise precautions. If you plan to fish at night, bring a powerful headlamp and extra batteries. Wear a life jacket at all times on the water.

Frequently Asked Questions

Do I need a guide to fish Iatt Lake?

No. The lake is small enough and shallow enough that you can navigate it safely with a map, GPS, or basic local knowledge. Many anglers fish it without a guide. If you are unfamiliar with shallow-water navigation or want to learn the best spots quickly, a local guide can be worth the cost, but it is not necessary.

What is the best time of day to fish?

Early morning (sunrise to 9 a.m.) is most productive year-round. Late afternoon and evening also produce, especially in spring. Midday is typically slow, particularly in summer. Night fishing for catfish is excellent from June through September.

Can I fish from the bank?

Bank access is limited. Most of the shoreline is private property or thick marsh. A few spots near the boat launch allow shore fishing, but a boat is the practical way to fish Iatt Lake. Kayaks and canoes launched from the ramp work well for anglers without a motorized boat.

What happens if the water level drops?

Low water in late summer and fall concentrates fish in the deeper central basin but makes navigation hazardous. Many anglers avoid the lake during these periods. If you do fish during low water, operate at idle speed and watch carefully for stumps and cypress knees.

Is there a bait shop near the lake?

No bait shop is located directly at Iatt Lake. Bastrop, about 20 miles north, has sporting goods stores and bait shops. Plan to buy bait and supplies before you arrive at the lake, or bring your own.
