What You'll Find at Cataouatche Lake

Cataouatche Lake is a shallow, brackish estuary about 40 miles southeast of New Orleans, accessible from the town of Yscloskey at the end of Highway 46. The lake sits where freshwater from the Mississippi River mixes with Gulf saltwater, creating conditions that hold redfish and speckled trout year-round. Depths range from 2 to 6 feet across most of the lake, with scattered shell reefs and grass beds that concentrate fish in predictable spots.

The lake's character changes with the seasons and tides. Winter brings cooler water and tighter schools of redfish in the deeper holes and along the shell reefs. Spring and fall offer the most consistent action, with fish spread across the flats and grass beds. Summer heat pushes fish into deeper water and into the early morning and late evening hours. Tides matter more here than on the open Gulf—a rising tide floods the shallow grass beds and brings feeding fish into water you can reach from a small boat or wade.

Access is limited to boat launch at Yscloskey, a small marina community at the end of the road. There is no public shoreline fishing; you must have a boat or hire a guide. The nearest services—fuel, food, lodging—are in Yscloskey or back toward Chalmette. Plan for a 45-minute to one-hour drive from New Orleans proper.

Key Takeaways

  • Cataouatche Lake holds redfish and speckled trout in shallow brackish water, with the best fishing on rising tides and in grass beds and shell reefs.
  • Access is by boat only from the Yscloskey launch; there is no public shore fishing and limited services in the area.
  • Winter fishing concentrates on deeper holes and reefs; spring and fall offer the most consistent action across the flats.
  • Louisiana saltwater fishing license and redfish tag are required; check current bag limits and size restrictions before you fish.
  • Shallow-draft boats (skiffs, kayaks, canoes) work best because most of the lake is 2 to 4 feet deep and navigation requires local knowledge.

Seasons and Tides at Cataouatche

Spring (March through May) is the most reliable season. Water temperatures climb into the 60s and 70s, and redfish move onto the shallow flats to feed. Speckled trout are active throughout the day, and you can sight-cast to tailing redfish in the grass beds on calm mornings. Tides are moderate and predictable; plan your trip around a rising tide, which pushes fish into the shallows.

Fall (September through November) mirrors spring in many ways. Water cools from summer heat, fish spread out again, and the grass beds become productive. October and early November often see the year's best redfish bite. Afternoon tides tend to be stronger in fall, so plan your fishing window around the tide schedule rather than the clock.

Winter (December through February) concentrates fish in the deeper holes—4 to 6 feet—and along the shell reefs where they hold in cooler water. The bite is slower and more technical; you need to find the exact depth where fish are holding. Redfish are catchable but less aggressive than in warmer months. Speckled trout fishing can be excellent on calm days when you can sight-fish the deeper flats.

Summer (June through August) is the hardest season. Heat pushes fish deep and into low-light hours. Early morning (before 8 a.m.) and late evening (after 6 p.m.) are your only reliable windows. Midday fishing is slow unless you find deep holes or shade under docks. Mosquitoes are relentless; bring insect repellent and long sleeves.

Regulations and Licensing

You must have a Louisiana saltwater fishing license to fish Cataouatche Lake. Licenses are sold online through the Louisiana Department of Wildlife and Fisheries (LDWF) website, at Yscloskey marinas, and at sporting goods stores. A three-day non-resident license costs less than a full-year license if you are visiting for a short trip.

Redfish require a separate redfish tag in addition to your license. Each tag allows you to keep one redfish per day. Tags are included with some license packages or sold separately. Speckled trout have no tag requirement but do have a daily bag limit and size restriction—check the current LDWF regulations before you fish, as these change year to year.

Current size and bag limits for redfish and speckled trout are posted on the LDWF website. Redfish typically must be between 18 and 28 inches; speckled trout are usually 12 inches minimum. Possession limits and closed seasons vary, so verify the rules for the specific dates you plan to fish. Guides operating on the lake are familiar with current regulations and will keep you compliant.

Boats and Access from Yscloskey

Yscloskey is a working fishing village at the end of Highway 46, about 40 miles from downtown New Orleans. The boat launch is basic but functional; there is a concrete ramp and limited parking. Arrive early on weekends, as parking fills quickly. The launch fee is modest and usually paid at the marina office or a nearby tackle shop.

Shallow-draft boats are essential. Redfish skiffs (16 to 18 feet with a poling platform) are ideal if you own one or can rent. Kayaks and canoes work well for anglers willing to paddle and fish shallow water slowly. Larger center-console boats can fish Cataouatche but are overkill for the depth and distance involved. If you do not own a boat, several guides operate out of Yscloskey and can take you to the productive areas; expect to pay for a full-day charter.

Navigation requires local knowledge or a GPS unit loaded with the lake's shallow spots and hazards. Unmarked shell reefs and stumps are common; running at speed in unfamiliar water risks hitting bottom or damaging your prop. If you are new to the lake, hire a guide for your first trip or fish with someone who knows the water.

Fuel and basic supplies are available at Yscloskey marinas, but selection is limited. Bring food, water, and extra tackle from New Orleans. Cell service is spotty on the water, so do not rely on it for navigation or emergency contact.

Redfish and Speckled Trout Tactics

Redfish in Cataouatche respond to sight-casting and blind casting depending on the season and water clarity. In spring and fall, wade the shallow grass beds on a rising tide and look for tailing fish—their tail breaking the surface as they feed in 1 to 3 feet of water. Cast a topwater plug or soft plastic ahead of the fish and work it slowly. In winter, fish the deeper holes and shell reefs with live shrimp or cut mullet on the bottom.

Speckled trout are less predictable but often school in the same grass beds as redfish. They respond well to small topwater plugs, soft plastics, and live shrimp. Early morning and late evening are most productive. In summer, focus on the deepest holes and fish during low-light hours.

Live shrimp is the most reliable bait year-round. Bring a cast net or buy shrimp at Yscloskey. Soft plastic lures in natural colors (tan, pearl, chartreuse) work well when sight-casting. Topwater plugs create commotion that attracts both species, especially in shallow water on calm mornings.

When to Fish and What to Expect

Plan your trip around the tide schedule, not the calendar. A rising tide is almost always better than a falling tide because it pushes fish into the shallows. Check tide tables for the Yscloskey area before you go. Many anglers fish the two hours before high tide and the hour after, when fish are most active in shallow water.

Water clarity varies. After heavy rain, the lake can be murky from freshwater runoff. After a few days of dry weather, the water clears and sight-casting becomes possible. Cloudy water does not shut down the bite, but you will rely more on blind casting and bait fishing.

Weather is the biggest variable. Wind makes the shallow water choppy and pushes fish deeper. Calm mornings are ideal. Afternoon wind is common in spring and fall; plan to fish early and leave by midday if the forecast calls for wind. Summer thunderstorms can develop quickly; watch the sky and head back to the launch if storms approach.

Nearby Options and Alternatives

If Cataouatche is too shallow or crowded, Lake Borgne lies just to the east and offers slightly deeper water and a different fish population. Breton Sound to the south is larger and more exposed to Gulf conditions but holds bigger redfish and speckled trout. Both require a boat and are accessible from similar launch points in the Yscloskey area.

For a different experience, the Mississippi River Gulf Outlet (MRGO) and the canals around it hold redfish and speckled trout in a more structured environment. These narrow waterways are easier to navigate than open lakes and often hold concentrated fish, especially in winter.

If you prefer guided fishing without the learning curve, several charter captains operate out of Yscloskey and nearby marinas. A guide will put you on fish, teach you the water, and handle navigation—a worthwhile investment if you are new to the area or want to maximize your time.

Frequently Asked Questions

Can I fish Cataouatche Lake from shore?

No. There is no public shoreline access to Cataouatche Lake. You must have a boat to fish. The only launch is at Yscloskey, and from there you navigate to the productive flats and reefs by water.

What is the best time of year to fish Cataouatche?

Spring (March to May) and fall (September to November) are most consistent. Water temperatures are moderate, fish are spread across the flats, and tides are predictable. Summer is difficult due to heat; winter requires deeper fishing and more technical skills.

Do I need a guide, or can I fish on my own?

You can fish on your own if you have a boat and local knowledge or a GPS unit with the lake mapped. First-time visitors benefit from a guide who knows the shallow spots, reefs, and seasonal patterns. Hiring a guide for one trip is a good way to learn the water before returning solo.

What size boat do I need?

A shallow-draft skiff (16 to 18 feet) is ideal, but kayaks and canoes work well for anglers willing to paddle. Larger boats can fish the lake but are harder to navigate in 2 to 4 feet of water. Avoid deep-V hulls that require deeper water to operate safely.

How far is Cataouatche Lake from New Orleans?

About 40 miles southeast via Highway 46 to Yscloskey. The drive takes 45 minutes to one hour from downtown New Orleans. Yscloskey is a small village with limited services; bring fuel, food, and supplies from the city.
