What Lake Fields Offers

Lake Fields is a shallow, brackish impoundment in central Lafourche Parish that holds redfish, spotted seatrout, and largemouth bass year-round. The lake sits inland from the Gulf, fed by canal systems that bring saltwater influence during high tides and freshwater runoff during heavy rain. This mix makes it unpredictable — the salinity can swing from nearly fresh to full-strength Gulf water in a matter of weeks — but that instability is also what keeps fish concentrated and feeding.

The lake runs roughly 3 miles long and averages 4 to 6 feet deep, with scattered cypress and dead trees providing structure. Most of the shoreline is marsh grass, and the bottom is soft mud with occasional shell beds. Access is limited compared to larger Lafourche Parish waters, and that works in your favor: fewer boats mean less pressure on the fish and more predictable patterns.

Key Takeaways

  • Lake Fields holds redfish and spotted seatrout year-round, with redfish most active in spring and fall and trout peaking in winter and early summer.
  • The lake's salinity shifts with tides and rainfall, so check recent conditions before you fish — brackish water in summer often means better redfish, while saltier water in winter favors trout.
  • Shallow-running crankbaits, soft plastics on light jigs, and topwater plugs work best in water that rarely exceeds 6 feet deep.
  • Launch access is limited; confirm the boat ramp is open and passable before making the drive, as canal levels can close access for weeks.

Redfish in Spring and Fall

Redfish move into Lake Fields during spring (March through May) and again in fall (September through November), when water temperatures sit between 65 and 75 degrees. They hunt the shallow grass flats and the edges of the dead-tree structure, feeding hard on mullet and shrimp. Early morning and late afternoon are most productive, though redfish here will bite through midday if the water is cloudy.

Fish the grass edges with 3/8-ounce jigs tipped with 3-inch soft plastics in natural colors — pearl, chartreuse, or tan. Cast parallel to the grass line rather than into it; redfish hunt the transition zone where they can see prey but stay near cover. If you see tailing fish in the shallows, a topwater plug worked slowly will draw strikes, but be patient — these fish spook easily in water this clear.

Fall redfish are typically larger and more aggressive than spring fish, and they stay longer if water temperatures drop slowly. A hard freeze can push them out into deeper canals, so monitor the forecast and fish the warmest part of the lake — usually the western end — if a cold snap is coming.

Spotted Seatrout in Winter and Early Summer

Spotted seatrout dominate Lake Fields from December through June, with the peak bite occurring in January and February when water temperatures drop to 55 to 65 degrees. Trout stack up in the deepest holes — usually 5 to 7 feet — and around the cypress and dead-tree structure. They are less aggressive than redfish but more predictable; a slow, steady retrieve with a small jig or soft plastic will produce consistent catches.

Use 1/4-ounce jigs with 2-inch plastics in white, chartreuse, or natural shrimp patterns. Fish the structure vertically or with short casts, letting the jig fall on a slack line so trout can take it on the drop. Early morning is most productive, but trout will bite throughout the day if you stay on the structure. Avoid the shallowest water — trout here prefer 4 feet or deeper, even in winter.

By June, water temperatures climb above 80 degrees and trout move into the deepest canals or leave the lake entirely. Summer fishing is slow, and most anglers shift focus to redfish or move to other Lafourche Parish waters with better summer action.

Dealing with Salinity Changes

Lake Fields' salinity is its defining feature and its biggest wildcard. After heavy rain, the lake can turn nearly fresh within days, pushing saltwater fish deeper into the canals and bringing in largemouth bass and other freshwater species. During dry spells or high tides, Gulf water pushes in and the lake becomes brackish or salty, favoring redfish and trout.

Check the salinity before you fish by calling the Lafourche Parish Sheriff's Office marine patrol or asking at local tackle shops — they track conditions weekly. Brackish water (5 to 15 parts per thousand) is ideal for both redfish and trout. Freshwater conditions favor largemouth bass on soft plastics and crankbaits around the cypress, but bass fishing here is secondary to saltwater species. Highly saline water (above 25 ppt) concentrates trout and redfish but can make them finicky; slow your retrieve and use smaller baits.

Tackle and Technique for Shallow Water

Lake Fields rarely exceeds 6 feet deep, so heavy tackle is unnecessary and often counterproductive. A 6-foot medium-light spinning rod with 8- to 10-pound braided line gives you sensitivity to feel the soft bottom and detect subtle strikes. Pair it with a 12-pound fluorocarbon leader to reduce visibility in clear water.

Shallow-running crankbaits in shad patterns work well when fish are active and feeding in open water. Topwater plugs — especially walking-style plugs — produce explosive strikes in early morning and late afternoon, particularly for redfish. Soft plastics on light jigs are the most versatile option: they work in all seasons, all salinity levels, and all depths. Keep a selection of 2- to 3-inch plastics in white, chartreuse, natural shrimp, and mullet patterns.

Avoid heavy sinkers and deep-diving baits. The lake's shallow, soft bottom means you will snag constantly with anything heavier than 3/8 ounce. If you are losing jigs regularly, you are fishing too deep or too heavy for the conditions.

Launch Access and Timing

Lake Fields has one primary launch: the Lafourche Parish boat ramp near the intersection of Highway 1 and Canal Boulevard in Mathews. The ramp is public and free, but it is narrow and can be crowded on weekends. More importantly, canal levels fluctuate with rainfall and tidal cycles, and the ramp can become impassable for weeks during drought or after dredging work.

Call ahead — the Lafourche Parish Sheriff's Office marine patrol can tell you if the ramp is open and passable. Arrive early to avoid the afternoon crowd, and be prepared to wait if other trailers are launching. The ramp is maintained but not always in perfect condition; a high-clearance vehicle helps, especially after heavy rain when the approach can be soft.

Tides matter less here than in open Gulf waters, but they do affect canal levels and salinity. Fish the incoming tide if you want saltier water and better trout fishing; fish the outgoing tide for fresher conditions and better redfish. Check tide tables for nearby Port Fourchon or Cocodrie to predict conditions.

Seasonal Patterns and What to Expect

Winter (December to February) is the most reliable season. Water temperatures are stable, trout are concentrated, and salinity is usually brackish. Expect consistent action on jigs and soft plastics, especially in the morning. Dress warmly — wind can make the lake feel colder than the actual water temperature.

Spring (March to May) brings redfish and warming water. Salinity can swing wildly as spring rains arrive, so conditions change week to week. Topwater and jigs both work, but you may need to adjust your location and technique as the lake transitions. By late May, water temperatures climb above 80 degrees and the bite slows.

Summer (June to August) is slow. Most anglers avoid Lake Fields during this season and fish deeper canals or move to other parishes. If you do fish, early morning is essential, and focus on the deepest holes and the shadiest structure.

Fall (September to November) mirrors spring: redfish return, water temperatures drop, and salinity stabilizes. October is often the best month of the year. By November, water temperatures drop below 65 degrees and trout begin to concentrate, setting up the winter bite.

Frequently Asked Questions

What is the best time of day to fish Lake Fields?

Early morning (one hour before sunrise to mid-morning) is most productive year-round. Trout bite best in winter mornings; redfish bite throughout the day but are most aggressive at dawn and dusk. Avoid midday in summer unless the water is very cloudy.

Do I need a guide to fish Lake Fields?

No, but the lake is small enough that a guide can show you the structure and salinity patterns in one trip, which saves time if you are unfamiliar with Lafourche Parish waters. Local tackle shops can recommend guides or point you to productive areas.

Can I fish Lake Fields with live bait?

Yes. Live mullet and live shrimp work well for redfish and trout, especially in fall and winter. Use a simple slip-sinker rig with a 12-pound fluorocarbon leader, and fish the structure or grass edges. Live bait is slower than artificials but often produces larger fish.

What happens if the boat ramp is closed?

If the main ramp is impassable, you may be able to launch from canal access points along Highway 1, but these are informal and conditions vary. Call the Sheriff's Office marine patrol before attempting an alternate launch. Some anglers wade-fish the canals, but this is slow and limited to shallow areas.

Is Lake Fields good for beginners?

Yes. The lake is small, shallow, and forgiving. Fish are predictable by season, and you do not need specialized tackle or technique. The main challenge is access — confirm the ramp is open before you drive out, and plan for limited parking on weekends.
