🎣 Fishing Spot: Indian River Lagoon (Treasure Coast)

🏞️ General Details About Indian River Lagoon - Treasure Coast

Indian River Lagoon—stretching through Indian River and St. Lucie counties along Florida's Treasure Coast—represents one of North America's most biologically diverse and productive estuarine systems. This shallow, brackish water lagoon extends roughly 60 miles from Sebastian Inlet south through Vero Beach, Fort Pierce, and Stuart, creating an inland waterway separated from the Atlantic Ocean by barrier islands. With average depths of just 3-4 feet across vast grass flats, intricate mangrove shorelines spanning hundreds of miles, and limited tidal exchange creating stable salinity, the Treasure Coast section of Indian River Lagoon produces consistent year-round fishing for snook, redfish, spotted seatrout, tarpon, and black drum—all within sight of luxury waterfront homes, historic fishing villages, and pristine natural preserves.

🌟 Why Indian River Lagoon (Treasure Coast) Is Special

• World-Class Snook Fishery
  The Treasure Coast lagoon has earned legendary status among serious snook anglers, producing trophy fish exceeding 40 inches and 20+ pounds alongside abundant slot-sized fish. The lagoon's extensive mangrove habitat, consistent baitfish populations, minimal fishing pressure compared to South Florida, and protective management create ideal conditions for growing big snook. Spring through fall (when regulations allow) produces explosive topwater action along mangrove shorelines at dawn and dusk. Winter concentrations around deep holes, residential docks, and warm-water discharges offer cold-weather opportunities. Many consider the Vero Beach to Stuart stretch among Florida's top five snook destinations for consistent trophy potential.

• Redfish Paradise with Trophy Potential
  Indian River Lagoon supports exceptional redfish populations from juvenile "rat reds" (14-20 inches) providing nonstop action to monster bull redfish (35-45 inches, 15-30 pounds) testing tackle limits. The shallow grass flats, oyster bar systems, mangrove edges, and spoil island shorelines create diverse habitat supporting all life stages. Fall through spring brings peak action—cooler water concentrates fish, tailing opportunities increase on shallow flats during calm mornings, and aggressive feeding precedes winter's slower metabolism. The lagoon's fertility grows quality fish quickly while protective slot limits preserve breeding stock. Redfish here exhibit less wariness than heavily-pressured South Florida fish, making them accessible to anglers of all skill levels.

• Exceptional Seatrout Populations
  Spotted seatrout thrive throughout the Treasure Coast lagoon, with grass flat systems providing ideal habitat. Average fish run 14-20 inches (1-3 pounds), but trophy "gator trout" exceeding 25 inches and 7+ pounds are caught regularly, particularly during winter months when big females stage in deeper holes preparing for spring spawn. The lagoon's consistent grass coverage creates stable populations less vulnerable to cold kill events affecting other Florida regions. Fall brings incredible concentrations—schools of dozens to hundreds of trout work grass flats from dawn through mid-morning, producing nonstop topwater action. The aggressive strike, acrobatic jumps, and delicate eating quality make seatrout perfect light-tackle targets.

• Tarpon Migration Highway
  From April through September, massive schools of migratory tarpon (80-150+ pounds) move through the Treasure Coast lagoon, staging near inlets, cruising grass flat edges, and providing world-class sight-fishing opportunities. Unlike some tarpon fisheries requiring offshore boats or specialized guides, lagoon tarpon are accessible to flats boats, kayaks, and even wade fishers willing to explore. Early morning hours often reveal laid-up tarpon schools in 3-6 feet of water—visible as dark shadows or occasional rolling fish—creating fly fishing and light-tackle casting opportunities rivaling anywhere globally. Resident juvenile tarpon (20-60 pounds) occupy the lagoon year-round, particularly around bridges, residential canals, and deeper channels.

• Minimal Tidal Influence Creates Unique Fishing
  The lagoon's microtidal nature (6-12 inch fluctuation) eliminates traditional tide-dependent fishing strategies, creating advantages and challenges. Advantages: fish all day without waiting for specific tidal windows; explore freely without worrying about getting stranded on dropping tides; fishing pressure spreads across all times rather than concentrating at "prime tide" hours. Challenges: fish roam rather than stage predictably; must cover water actively to find fish; subtle environmental cues (wind direction, temperature changes, barometric pressure) matter more than tide charts. This creates a thinking angler's fishery rewarding observation, pattern recognition, and adaptability over rote tide-following.

• Outstanding Kayak Fishing Destination
  Shallow depths (2-5 feet across vast areas), protected waters (barrier islands block ocean swells), extensive shorelines accessible only to shallow-draft vessels, and consistent fish populations make the Treasure Coast lagoon ideal for kayak fishing. Launch from numerous ramps, paddle residential shorelines at dawn targeting snook around docks, work grass flat edges for tailing redfish, explore mangrove creeks inaccessible to larger boats, and enjoy solitude impossible in boat-traffic areas. Many lagoon regulars fish exclusively from kayaks, developing intimate knowledge of backwaters, creeks, and hidden spots producing consistently. Kayak fishing also significantly reduces cost barriers to entry while providing excellent exercise and wildlife observation opportunities.

• Diverse Habitat in Compact Area
  Within a few miles, the Treasure Coast lagoon offers incredible habitat diversity: expansive grass flats (sight-fishing for reds and trout), mangrove-lined shorelines (snook ambush zones), oyster bars (redfish, black drum, sheepshead), spoil islands (circumnavigating while casting to edges), deep holes (winter refuges and trophy trout), residential dock lines (structure fishing), bridge pilings (snook, tarpon, sheepshead), and tidal creek systems (exploring backwaters). This variety allows adjusting to conditions, targeting different species, and maintaining fresh fishing experiences without traveling far. A single day might involve sight-casting to tailing reds on flats, working topwater along mangroves for snook, and finishing with live bait around a bridge for tarpon.

• Less Fishing Pressure Than South Florida
  While Miami, Fort Lauderdale, and West Palm Beach's lagoon sections see intense daily pressure from guides and recreational anglers, the Treasure Coast maintains comparatively lower angler density despite similar or better fishing quality. This translates to less-educated fish responding more aggressively to presentations, less competition for productive spots, and more solitude on the water. Anglers willing to explore beyond the most obvious ramps and well-known areas discover fishing reminiscent of "old Florida"—abundant fish, minimal pressure, and unspoiled shorelines. The region's smaller population and tourist base compared to Southeast Florida creates this advantage.

• Year-Round Consistency with Seasonal Peaks
  Unlike fisheries with pronounced on/off seasons, the Treasure Coast lagoon produces every month with seasonal variations enhancing rather than dictating success. Winter (Dec-Feb) offers excellent sight-fishing on warm days, trophy seatrout in deeper water, and concentrated snook around warm-water sources. Spring (March-May) brings pre-spawn snook aggression, early tarpon arrivals, and explosive dawn topwater action. Summer (June-Aug) delivers tarpon peak, aggressive snook feeding (when regulations allow), and consistent action despite heat. Fall (Sept-Nov) provides optimal conditions—comfortable temperatures, peak redfish and seatrout activity, lingering tarpon, and some of the year's best overall fishing. Every month offers quality opportunities; no season truly disappoints.

• Excellent Fly Fishing Opportunities
  The lagoon's shallow depths, clear water windows, sight-fishing potential, and concentrated fish populations create world-class fly fishing accessible from shore, kayak, or flats boat. Sight-casting to tailing redfish on grass flats, working streamers along mangrove edges for snook, targeting laid-up tarpon schools during calm mornings, and stripping flies over grass for seatrout—all produce regularly. The lagoon forgives beginner fly casters (soft presentations matter less than in ultra-clear Bahamas flats) while challenging experts with technical shots to spooky fish. Many visiting anglers specifically target the lagoon for accessible, productive fly fishing without requiring expensive lodge trips.

• Rich Fishing Heritage and Local Knowledge
  The Treasure Coast has supported fishing communities for generations—from commercial mullet fishermen to rod-and-reel pioneers to modern conservation-minded anglers. Local tackle shops in Vero Beach, Sebastian, Fort Pierce, and Stuart employ knowledgeable staff who provide honest fishing reports, pattern information, and tackle recommendations. Guide services offer specialized knowledge accelerating learning curves for visiting anglers. Fishing clubs and conservation organizations create community around shared passion for the lagoon. This culture of information-sharing and stewardship makes the region welcoming to newcomers while preserving traditions valuing the resource over individual catches.

• Proximity to Other Fishing Opportunities
  The Treasure Coast lagoon serves as a base for exploring diverse fishing: run through Fort Pierce Inlet for offshore trolling, bottom fishing, and inlet snook/tarpon action; explore Sebastian Inlet for world-famous surf fishing and inlet jetty opportunities; fish the St. Lucie River system for freshwater/brackish species mixing; access Atlantic surf fishing along barrier island beaches; target bridge and causeway structure throughout the region. This variety allows adjusting to weather, testing different techniques, and maintaining fresh challenges without extensive travel. A week-long Treasure Coast fishing trip can include lagoon, inlet, surf, river, and nearshore ocean fishing—all within 30 minutes' drive.

🎯 Mastering Indian River Lagoon (Treasure Coast): Advanced Techniques

Success on the Treasure Coast lagoon requires understanding shallow-water fish behavior, reading subtle environmental cues, and adapting to minimal tidal influence. These three techniques unlock consistent catches.

🎯 Technique #1: Dawn Topwater Assault on Mangrove Shorelines for Trophy Snook

Overview
The hour surrounding sunrise—from 30 minutes before first light through 60 minutes after—produces the Treasure Coast lagoon's most explosive fishing action. During this magical window, trophy snook (30-40+ inches) abandon deep-water holding areas and move shallow along mangrove shorelines to ambush mullet, pilchards, and other baitfish actively feeding near the surface. The combination of low light (reducing snook wariness), active baitfish (triggering predatory response), comfortable water temperatures (spring through fall), and structure proximity (mangroves provide quick escape routes) creates ideal conditions for aggressive topwater strikes that define what makes snook fishing addictive.

Working topwater plugs along mangrove edges during dawn requires specific techniques: understanding how to position relative to shoreline and sun angle, making accurate casts to precise targets without spooking fish, working lures with cadence that triggers strikes, setting hooks properly on explosive surface blowups, and fighting powerful fish near structure. Master this technique and you'll experience some of inshore fishing's most thrilling moments—watching a trophy snook's mouth engulf your lure in a surface explosion, feeling the immediate weight and power, battling a fish determined to reach mangrove roots, and landing a specimen that will replay in your memory for years.

When to Deploy This Technique

• Prime Season: April-October when snook regulations allow (verify current FWC rules)
• Optimal Time: 30 minutes before sunrise through 60 minutes after sunrise
• Best Conditions: Calm mornings (wind under 10 mph); overcast skies extend bite window
• Water Temperature: Above 72°F (snook less active in cooler water)
• Moon Phase: Days surrounding full and new moons produce best action

Understanding Snook Behavior at Dawn

Why Dawn Produces:

Baitfish Activity:

• Small baitfish (pilchards, glass minnows) feed actively at dawn
• Rise in water column and move shallow
• Create visible surface activity—dimples, swirls, flashes
• Snook position to intercept

Light Levels:

• Low light reduces snook wariness
• Fish move shallower than during bright sun
• Predators have vision advantage over prey
• Aggressive feeding window before sun increases visibility

Temperature Comfort:

• Night cooling makes shallow water comfortable
• Morning sun hasn't heated shallows yet
• Snook actively feed before day's heat builds

Snook Positioning:

Tight to Mangroves:

• Within 1-3 feet of mangrove edge
• Face away from mangroves toward open water—watching for prey
• Use overhanging branches and roots as cover
• Quick escape route if spooked

Points and Indentations:

• Where mangrove line juts out (points) or curves in (pockets)
• Current (minimal but present) deflects around points
• Pockets concentrate baitfish—classic ambush zones
• Priority targets

Creek Mouths:

• Where tidal creeks meet main lagoon
• Slightly deeper water provides staging area
• Baitfish move in/out with water flow
• Often hold multiple snook

1. Points: Where mangroves jut out into lagoon—cast to point and both sides

2. Creek Mouths: Slightly deeper water at tidal creek entrances—work thoroughly

3. Pockets: Indentations in mangrove line—baitfish concentrate here

4. Overhanging Trees: Extra shade and structure—snook often underneath

5. Uniform Shoreline: Even stretches without obvious structure hold fish—don't skip

Cast Placement:

• 5-10 feet from mangrove edge—not hitting branches
• Parallel to shore when possible—keeps lure in strike zone longer
• Perpendicular to shore at points, creek mouths—covers specific structure

🎯 Technique #2: Sight-Fishing Tailing Redfish on Grass Flats

Overview
Few inshore fishing experiences match the visual excitement of sight-fishing tailing redfish on shallow grass flats. During optimal conditions—calm winds, good water clarity, comfortable temperatures—redfish move onto 1-3 foot flats searching for crabs, shrimp, and other crustaceans living in seagrass. While feeding head-down in grass, their copper-colored tails break the surface, waving like flags revealing their location. Spotting these tails from 50+ feet away, positioning for a cast, presenting a lure or fly accurately without spoking the fish, watching the tail's reaction to your offering, and setting the hook on a visual eat creates hunting-style fishing that engages mind and body completely.

The Treasure Coast lagoon offers extensive grass flat systems ideal for sight-fishing—particularly areas from Sebastian through Vero Beach where water clarity supports seeing fish. Fall through spring produces optimal conditions as cooler water temperatures, stable weather patterns, and lower winds create glassy morning surfaces revealing tailing fish clearly. Learning to spot tails, understand redfish feeding behavior, make stealthy approaches, and present lures properly transforms random fish encounters into predictable success.

When to Deploy This Technique

• Prime Season: September-April (cooler water increases tailing activity)
• Peak Months: October-December and February-April
• Optimal Conditions: Wind under 5 mph; water clarity 2+ feet; sunny or lightly overcast
• Best Times: Dawn through mid-morning (calm winds); occasionally late afternoon
• Water Temperature: 65-78°F ideal; fish still tail outside this range but less frequently

Understanding Tailing Behavior

Why Redfish Tail:

Feeding Position:

• Redfish tip head-down feeding on bottom
• Body angle causes tail to break surface
• Not intentional—byproduct of feeding posture
• Tail waves slowly as fish moves/feeds

What They're Eating:

• Crabs (primary food)—blue crabs, fiddlers, mud crabs
• Shrimp in grass and mud
• Small fish occasionally
• Other crustaceans and invertebrates

Optimal Tailing Conditions:

Water Depth:

• 1.5 to 3 feet—ideal tailing range
• Shallower: fish struggle to feed effectively
• Deeper: tails don't break surface (fish still there, just not visible)

Bottom Type:

• Grass flats with potholes—prime
• Mixed grass and sand patches
• Areas with slightly softer bottom (easier digging)

Water Clarity:

• 2+ feet visibility minimum for spotting tails
• Clearer water better (3-4 feet visibility = excellent)
• Stained water makes spotting difficult

🎯 Technique #3: Night Fishing Deep Holes and Lighted Docks for Trophy Seatrout

Overview
When air temperatures drop during fall and winter, big spotted seatrout—the 24-26"+ "gator trout" exceeding 6 pounds—concentrate in deeper holes (6-12 feet) scattered throughout the Treasure Coast lagoon. These depressions in otherwise shallow flats, often adjacent to channels or spoil islands, provide slightly warmer water during cold nights and stage pre-spawn females preparing for spring spawning. Fishing these holes at night using suspending jerkbaits, live shrimp under popping corks, or slow-worked soft plastics produces trophy seatrout at higher rates than random daytime flat fishing, particularly during coldest months (December-February).

Combining deep hole fishing with lighted dock structure creates an even more productive night strategy. Residential docks with lights attract glass minnows and other baitfish, which attract seatrout, snook, and other predators. Working these lighted zones systematically—casting from darkness into light, using jerkbaits and soft plastics, presenting live bait properly—produces consistent action during evening hours when daytime fishing slows.

When to Deploy This Technique

• Prime Season: November-March (winter concentrations of trophy trout)
• Peak Months: December-February (coldest water = tightest concentrations)
• Best Timing: 7pm-midnight (1-3 hours after dark most productive)
• Water Temperature: Below 68°F (cooler water = deeper staging)
• Moon Phase: Full and new moon periods best; any moon phase workable

Understanding Night Behavior and Deep Hole Structure

Why Fish Deep Holes at Night:

Thermal Refuges:

• Deeper water retains warmth better than shallows
• 1-2°F warmer than surrounding flats
• Significant to cold-sensitive fish
• Attracts multiple species

Pre-Spawn Staging:

• Big female trout (24-28"+) prepare for spring spawn
• Concentrate in holes during winter
• Feeding to build energy reserves
• Multiple big fish often in single hole

Night Feeding:

• Seatrout feed actively at night
• Less wary than daytime
• Move slightly shallower than day positions
• Aggressive strikes on properly presented baits

What Constitutes a "Deep Hole":

Relative Depth:

• Lagoon averages 3-4 feet
• Holes are 6-12 feet deep
• Even 2-3 foot depressions can hold fish
• Transition zones most productive (where hole edges meet flat)

Hole Characteristics:

Location:

• Adjacent to spoil islands—dredge holes
• Near channels—scouring action creates depressions
• Middle of flats—natural depressions
• Random locations—find with electronics

Bottom Composition:

• Soft mud or sand
• Sometimes shell bottom
• Marks well on depth finders

Finding Holes:

• Use quality electronics—mark depth changes
• GPS mark productive holes—return repeatedly
• Ask local tackle shops—many share general areas
• Explore systematically—idle with depth finder watching

Lighted Dock Dynamics:

Why Lights Attract Fish:

• Lights attract zooplankton
• Baitfish feed on zooplankton
• Gamefish feed on baitfish
• Complete food chain under lights

Best Docks:

• Multiple lights (more illumination = more bait)
• Deeper water (6-10 feet) adjacent to dock
• Current or water movement nearby
• Isolated docks (less competition from other anglers)

🧭 Where to Fish Indian River Lagoon (Treasure Coast)

The Treasure Coast section of Indian River Lagoon spans roughly 60 miles through diverse habitat types. These locations provide starting points for your exploration.

Sebastian Area (Northern Indian River County)
Gateway to Treasure Coast lagoon. Sebastian Inlet State Park provides access to both inlet fishing and lagoon proper. North of inlet, explore grass flats extending west toward mainland—consistent seatrout and redfish water. Mangrove shorelines along barrier island (Orchid Island) hold snook dawn/dusk. Captain Forster Hammock Preserve offers primitive kayak access to mangrove systems—low pressure, quality fishing. Area known for clearer water than southern sections—good sight-fishing potential during optimal conditions. Multiple spoil islands worth exploring. Less development than Vero Beach areas creates more natural feel.

Vero Beach Area (Central Indian River County)
Most developed section but still productive fishing. Thousands of residential docks along barrier island shoreline create structure fishing opportunities similar to Banana River. Work docks systematically dawn/dusk for snook and seatrout. Western lagoon side features extensive grass flats—excellent for drifting or poling for seatrout and redfish. Round Island area accessible from park provides mangrove habitat and tidal creek systems. Herman's Bay south of Vero offers grass flat access with less boat traffic than central areas. Vero Beach Marina provides convenient launch but gets crowded weekends. Spoil islands scattered throughout—kayak destinations offering circumnavigation fishing. Water clarity variable—typically 1-3 feet visibility. Merrill P. Barber Bridge (Wabasso Causeway) provides structure fishing—snook, sheepshead, mangrove snapper.

Fort Pierce Area (Northern St. Lucie County)
Fort Pierce Inlet creates current and attracts fish—separate detailed coverage available. Inside lagoon, extensive grass flats stretch west from barrier island. North Causeway and South Causeway bridges offer structure fishing—snook, tarpon (seasonal), jacks. Dynamite Point area provides grass flat access. Spoil islands throughout this section—some of the lagoon's most productive. Mangrove shorelines along both mainland and barrier island sides. Water clarity moderate—1-2 feet typical. Area sees less fishing pressure than Vero Beach despite equal or better fishing. Fort Pierce City Marina provides downtown access—protected launch. Treasure Coast fishing guides concentrate here—local knowledge valuable.

St. Lucie River Junction (Southwest of Fort Pierce)
Where St. Lucie River meets Indian River Lagoon creates mixing zone—freshwater influence creates brackish conditions. Diverse species mix: lagoon saltwater species plus river species (largemouth bass, gar, catfish occasionally). Extensive mangrove systems throughout—kayak paradise. Tidal creek networks offer exploration fishing. Less fishing pressure—most boats head to inlet or main lagoon. Savannas Preserve State Park provides kayak access to pristine mangrove wilderness. Water quality concerns periodically affect this area (freshwater discharges from Lake Okeechobee)—check conditions before planning trips. When conditions good, exceptional fishing in unique environment.

Stuart Area (Southern St. Lucie County)
Southern extent of Treasure Coast lagoon. St. Lucie Inlet to south provides ocean access (separate from Fort Pierce Inlet). Inside lagoon, grass flats, mangroves, and spoil islands create diverse habitat. Jensen Beach Causeway area popular—boat ramp, shore fishing, bridge structure. Roosevelt Bridge (US 1) provides extensive structure—multiple lanes, numerous pilings, productive night fishing. Sandsprit Park offers well-maintained launch facilities. Area receives South Florida fishing pressure (proximity to West Palm Beach) but still productive. Water quality better than areas north (less freshwater discharge impact typically). Manatee Pocket and surrounding waters worth exploring—protected, less wind exposure.

Grass Flat Systems (Throughout Region)
Vast shallow grass flats (2-4 feet) extend throughout Treasure Coast lagoon—primary habitat type. Seatrout over grass; redfish along edges, in potholes. Turtle grass, shoal grass, manatee grass species create underwater meadows. Look for variations: potholes (slightly deeper areas—fish concentrate), sand patches (ambush zones), grass edges (transition zones), depth changes (even 6 inches matters). Drift or pole across flats systematically. Dawn through mid-morning most productive. Sight-fishing during calm conditions—spot tails, wakes, fish shadows. Use electronics to identify subtle bottom contours. Avoid running over seagrass—propeller scarring damages habitat.

Mangrove Shorelines (Both Sides of Lagoon)
Hundreds of miles of mangrove-lined shores—red, black, white mangrove species. Snook heaven—work topwater at dawn/dusk along edges. Redfish cruise mangrove roots searching for crabs. Tidal creeks cutting through mangroves offer exploration opportunities. Higher water stages put fish tighter to mangroves; lower stages concentrate fish in creeks and deeper edges. Cast parallel to mangroves when possible—keeps lure in strike zone longer. Oyster bars form at some mangrove edges—excellent redfish, black drum, sheepshead habitat. Approach quietly—fish spook easily in shallows. Mainland (west) side mangroves generally less developed, more natural than barrier island side.

Spoil Islands (Scattered Throughout)
Numerous spoil islands created from historical dredging operations dot the lagoon. Each island offers: mangrove shorelines (snook, redfish), oyster bars (multiple species), adjacent grass flats (seatrout, reds), deeper water nearby (channel edges). Circumnavigate islands while casting—cover all sides. North/south sides fish differently based on wind, sun angle. Some islands allow primitive camping (check regulations)—multiday fishing adventures. Less boat traffic near islands farther from ramps. GPS mark productive islands—return consistently. Islands create current breaks—fish stage in eddies. Kayak-friendly destinations—paddle to island, fish around it, explore.

Deep Holes (Scattered, Marked by Locals/Electronics)
Scattered depressions throughout lagoon—6-12 feet deep amid 3-4 foot flats. Winter trophy seatrout magnets—big females concentrate here. Also hold snook during cold snaps, black drum, sheepshead. Find with quality electronics—mark depth changes. GPS mark productive holes—guard them (locals sometimes protective of spots). Fish at night November-March—suspending jerkbaits deadly. Transition zones most productive (where hole edges meet flat). Multiple fish often in single hole—don't leave after one catch. Windward sides of holes sometimes better (current pushes bait toward edge).

Bridge and Causeway Structure (Multiple Locations)
Numerous bridges cross lagoon: Sebastian Inlet causeway, Wabasso Beach causeway, Merrill P. Barber Bridge, Fort Pierce causeways, Jensen Beach Causeway, Roosevelt Bridge (Stuart). Each provides structure fishing: pilings concentrate baitfish, attract predators, create current breaks. Snook around pilings; tarpon (seasonal) in channels; sheepshead and mangrove snapper around barnacle-covered pilings; black drum near deeper structure. Night fishing under lights excellent—work same technique as lighted docks. Day fishing during moving water (minimal tidal influence but some current). Shore fishing access at some bridges—catwalk or bank. Boat positioning critical—respect navigation channels, watch traffic.

Residential Canal Systems (Throughout Developed Areas)
Residential canals feeding into main lagoon create habitat diversity. Deeper water (6-10 feet) than main flats provides thermal refuges during cold weather. Dock lines along canals—structure fishing similar to main lagoon. Dead-end canals hold fish seeking shelter. Seawalls create vertical structure—work parallel with casts. Snook common in canals; seatrout during cooler months; tarpon (juvenile) year-round in some. Public water but respect private property—don't trespass on docks or yards. Lower boat traffic than main lagoon creates less-pressured fish. Approach quietly—sound travels in confined spaces.
