The I-95 Shrimp Highway: Shrimping the St. Johns River & Beyond

Up and down the Atlantic coast, shrimp make a massive summer migration into coastal inlets and rivers to spawn. In their search for nutrient-rich, brackish waters—the classic hallmark of a thriving estuary—these schools migrate in heavy waves dictated by moon phases, sometimes pushing an incredible 50 to 60 miles upstream into major river systems.

The St. Johns River in Northeast Florida boasts one of the most substantial and reliable summer shrimp runs on the entire East Coast. This unique river system becomes a massive shrimp superhighway, offering incredible action from Mayport on the coast south to Lake George, about 60 miles inland from the open Atlantic Ocean.

Unlike most rivers, the St. Johns flows south to north, dropping only about 30 feet in elevation along its entire 310-mile course. Because it flows so slowly, powerful ocean tides push saltwater deep inland, creating a massive brackish playground perfectly suited for migrating shrimp. While some folks bait shrimp at night in the shallows, targeting them during daylight hours in the deeper channels and holes is highly productive and much easier since you can see exactly what you’re doing.

Honorable mention to Volusia (Port Orange/South Daytona) and Flagler County (around Flagler Bridge): shrimp are caught near west channel markers in the intracoastal waters. NO ANCHORING. The channel experiences heavy boat traffic. The season can start as early as June and go to August.

Meet the species responsible for all the summer chaos and frenzy. The white shrimp with long antennae. Unlike winter shrimp, these dont make the best peel-and-eat compared to the winter species (Brown/Pink). They are fabulous when deep-fried and battered! These white shrimp with their trademark blue/green tail are now part of the winter shrimping season in Central Florida. These shrimp are light-tolerant, whereas their Brown and Pink counterparts, winter shrimp, are not.

The Seasonal Timeline: Tracking the Run

The shrimp run starts at different times depending on which part of the river you are fishing, heavily dictated by water temperatures and spawning cycles:

• April & May (The Spawn – CLOSED): Egg-bearing shrimp move onto the beaches and into the river mouth in early spring to spawn. Note: Shrimping is legally closed during these two months to protect the fishery’s future.
• Mid-July (The Kickoff): This is when the first reliable, catchable waves of the run show up. Expect plenty of “bait-sized” shrimp filling the nets early on.
• October & November (The Jumbo Peak): If you want the biggest shrimp of the year, this late-season window is your prime target.
• The Temperature Factor: Watch the thermometer. Warmer water over a mild winter can act as a massive accelerator for the season. The warmer the water, the faster the shrimp tend to grow—meaning we should see a significantly larger size class of shrimp moving through the river system this year!

Key Shrimping Hotspots & Coordinates (Cheat Sheet Coordinates – Bottom Of Article)

Shrimp are creatures of habit, congregating along the exact same river ledges, drop-offs, and structures year after year.

Green Cove Springs & Doctors Inlet (The Summer Hub)

Locals know Green Cove Springs is a mandatory stop on the shrimp’s journey from July through September.

• Spot 1: Black Creek (N 30°02.515', W 081°42.590')
  • The Run: Head north on the river after leaving the boat ramp; it is roughly 1.5 miles up on the western shoreline.
  • The Intel: The shrimp congregate just west of the bridge. They usually run a bit smaller here, but sheer numbers make up for it. Warning: Don’t cast too close to the bridge pilings—many a net has been lost here!
• Spot 2: West Shore (North of the Shands Bridge / SR 16) (N 29°59.049', W 081°37.655')
  • The Run: Head south from the ramp toward the bridge and look for the pier extending a couple hundred yards from the shoreline.
  • The Intel: This is the most consistent best bet on the river. The channel edge drops away rapidly from 3 feet down to 20 feet. Insider Tip: Watch the commercial crab traps! They mark right around where the drop-off begins. On some days, the shrimp sit in 7 to 10 feet of water; other days, you’ll have to venture deeper into the 17- to 20-foot range.
• Spot 3: South of the Shands Bridge (Eastern Shore) (N 29°59.151', W 081°36.645')
  • The Run: Located directly across the river, just south of the bridge footprint.
  • The Intel: The channel edge here is almost cliff-like, dropping from 3 feet to 30 feet in just 10 yards. Look for the shrimp hanging out around the middle depths (approx. 15 to 25 feet). This spot is sporadic—it can be ice-cold or produce lightning-fast limits.
• Live Green Cove Pier Update: Fresh intel shows massive activity right off the Green Cove Springs public pier. Multiple boats are actively stacked up just off the structure casting nets—an absolute visual guarantee that the shrimp are moving through.
• Doctors Lake Deep-Hole Report: While the shallower flats around Doctors Inlet have been slow lately, the shrimp have officially dug into the extreme deep water. Scan the bottom of Doctors Lake in the 37-foot holes. They are stacked thick right on the riverbed down there—mostly smalls and mediums. Drop your net deep away from the floater lines to lock them down.

Crucial Shands Bridge Field Intelligence

• East vs. West Battle: The East Shore south of the bridge is generally more productive than the West Shore. You’ll regularly see boats stacked up thick on the south-east side—they wouldn’t be idling there if the shrimp weren’t home!
• Net Destruction Warning: Do not cast on the north side of the east shore fishing pier. An old, severely damaged submerged pier down there will tear your net to shreds instantly. Anglers casting from the East Pier always throw to the south to stay clear of the wreckage.
• Bridge vs. Boats: Don’t underestimate land-shrimpers. The people throwing nets directly from the bridge structure are often just as productive as anyone out there in a boat.
• Live Shands Pier Status: For those without a boat, the pier action remains a steady option. Live reports show mostly smalls mixed with a few decent mediums being pulled up over the rail.
• Light Up the Night: If you are shrimping after dark, drop a submersible shrimp light into the water. The illuminated side of the hull consistently out-produces the dark side of the boat by a mile.
• Day & Night Shifting: During the day, stick to the deep channels and holes at the mouth of Doctor’s Lake or along the main channel south of the Shands Bridge. After dark, the shrimp spread out from the deep holes into the shallower waters. Homeowners with lighted docks on the water near the Green Cove Condos (N 29°59.648', W 081°40.576') easily fill their 5-gallon limits off their back steps.

Welaka, Turkey Island & Pomona Park (The Autumn Transition)

• The Run: Shrimping here is an absolute hotspot later in the season, burning bright between September and October as the schools make their maximum upriver push.
• Driving Route from DeLand (Southern Access): If you are trailering up from the DeLand area, take US 17 North, pass completely through Crescent City, and head into Pomona Park. At the main stoplight in town, turn left onto CR 308B. Follow this straight down, and it will take you directly to the public launch ramp footprint.
• The Target Zones: Once you launch, the river sits precisely 8 miles north of Lake George.
  • The Condos: Cruise exactly 1 mile south from the ramp to reach the deep-water staging shelves right in front of the local riverfront condos.
  • Turkey Island: Directly south of the condos, you will find Turkey Island. For the absolute sweet spot where the schools stack up thickest, focus your sonar on the East Side of the river near Turkey Island around Channel Marker 42. Two nets working the drop-offs in the deep channel right near Marker 42 can easily pack a cooler.
• The Intel: Welaka sits off US 17, approximately 15 miles south of Palatka. As an added bonus to the late-season shrimp push, the flounder fishing is on fire here throughout October!
• ⚠️ Real-Time Field Warning (Welaka / Georgetown Bug Hatch): Netters heading to the Welaka and Georgetown areas should prepare for intense bug pressure. A massive recent mosquito hatch has created an eerie anomaly on the water—huge, thick clumps of dead mosquitoes are floating in the St. Johns River, stretching for hundreds of yards. From a distance, it looks like a massive trail of dark lawn debris or grass clippings dumped in the river. If the bugs get too thick to breathe down south, pivot back to your reliable upriver safety blankets like Doctors Inlet and Black Creek.

Dunns Creek & Crescent Lake (The Deep Late-Season Run)

Further upriver lies Dunns Creek, a historic waterway averaging about 100 yards wide and mostly 8 to 15 feet deep (with some deeper holes dipping to 17 feet). In the late 1800s, this creek served as a bustling commercial artery for large paddlewheelers servicing Crescent City.

• The Run: While it is unusual for shrimp to push this far upriver and linger, massive late-season pushes turn Dunns Creek and Crescent Lake into an absolute goldmine through late October.
• The Intel: Tides here vary by about a foot daily, depending heavily on the winds down in Jacksonville. When the tide is moving, the current puts immense pressure on local crab trap floats.
• Harvesting Tactics: This area produces a dual bounty of shrimp and massive blue crabs. You can easily target them during the day out on Crescent Lake—even after a morning gator hunt, a single guy can cast a net in the deeper channels and pull a couple of gallons of shrimp in an hour or two.
• Nighttime Chaos: At night, the shrimp and crabs in Crescent Lake get so thick and jump so aggressively against the hull that you’ll wish you brought a dip net just to scoop them straight out of the air and into the boat!

Palatka, Lake George & Coastal Estuary Extensions

• Palatka Area: To reach the heart of the Palatka action, take SR 100 heading west off I-95. It will eventually turn into SR 20 and take you right into the area. Take Route 17 North until it merges with Route 100, head into East Palatka, and cross the Memorial Bridge.N 29°38.748', W 081°37.368'). At the end of the bridge, go straight to Third Street, then turn left. This takes you right to the excellent Palatka City Dock and Boat Ramp launch site.
• ⚠️ Palatka Public Dock Net-Snag Warning: If you are throwing from the public dock structure in Palatka, look closely for spots marked with a spray-painted “X.” Local netters mark these zones for a reason—severe, net-grabbing obstructions lie directly beneath them. Stay well away from the “X” marks unless you want to donate your expensive cast net straight to the bottom of the river!
• The Lake George Condos: For a highly popular late-season destination just south of Palatka, local scouts are currently checking on the Lake George Condos area. When the shrimp push out of the narrower river stretches, they group heavily on the flats and bars just where the river opens wide into Lake George. Keep your ears to the radio for live catches here.
• Jacksonville Area: For shrimpers looking further downriver toward the coast, many netters heavily utilize the walkways of the Trout River Bridge on the Jacksonville Northside.
• St. Augustine Coastal Bonus (Pine Island): If you venture just outside the river system to Pine Island off St. Augustine, the golden rule of shrimping remains the same: find the holes. Early casting on the flat bars might yield absolutely zero shrimp for the first 10 or 15 minutes. But if you scan your sonar to find where a deep hole cuts through, the payoff is immense. Dropping your net straight into a coastal deep hole can trigger an instant 100-shrimp-per-throw haul, filled with a beautiful mixed bag of smalls, mediums, and plenty of jumbo large ones, letting you limit out in under an hour.
• St. Augustine Coastal Secret (The Guana River Dam): For a stellar coastal alternative targeting migrating white shrimp, head to the Guana Tolomato Matanzas Reserve.N 30°00.866', W 081°20.570'). Located roughly 7.5 to 8 miles north of Vilano Beach/St. Augustine along North A1A, turn left onto Guana River Road.
  • The Structure: The dam impounds water to create a 3,240-acre brackish estuary (Lake Ponte Vedra).
  • The Strategy: Set up on the tidal saltwater side of the dam. The estuary drops into deep pockets ranging from 15 to 20 feet deep near the outfall structures.
  • The Ultimate Trigger: This spot goes on absolute fire when nor’easters blow in or major moon phases hit. Rising water levels and heavy ocean wind push massive surges of water against the dam, stacking white shrimp like cordwood in the deep tailwater pool.

The Technical Playbook: Methods & Variations

Shrimping methods vary drastically from location to location across Florida. Depending on water depth, structure, and time of day, you must adapt your tactics to fill your limit.

1. Daylight River Channel Edging (Deep Water Cast Netting)

During the daylight hours, shrimp run deep and hug the radical drop-offs along the river’s main channel edges.

• The Fleet Blueprint: Finding hot new territory is simple—look for clusters of local boats idling along a channel edge. Mark that exact line on your electronics and get ready to cast.
• The Big Daddy Net: This method requires heavy, large-radius cast nets—frequently scaling up to a 12-foot radius with a tight 3/8-inch square mesh. When thrown correctly, this net opens into a massive 24-foot sweeping circle that blankets the bottom. Because it covers so much acreage, a perfectly deployed 12-foot net can catch enough shrimp in just 3 or 4 throws to fill your bucket and send you home early.
• The Multi-Net Strategy: Throwing a 12-foot net takes serious muscle. Keep two nets on deck: a smaller, lighter scout net and the large “Big Daddy.” Throw the small one while you search for the run, deploy the large net once you find a thick school, and switch back to the small net if your arms start to wear out.

2. Nighttime Shallow Baiting (Stealth Cast Netting)

When darkness falls, a highly productive alternative method comes into play along the shallow shorelines of the St. Johns River.

• Charming the Spots: Netters prepare multiple shallow-water spots near the shore by using dry dog food as chum to create a highly concentrated attractant zone. Mark each baited area with a simple wooden stake so you can easily relocate it in the dark.
• The Silent Approach: After letting the spots sit for an hour or so to let the schools gather, approach the first marked stake by boat in total, dead silence.
• The One-Cast Limit: If your boat approach is quiet, the net is fully opened, and the cast is accurate, you will often catch an entire load of shrimp in one single throw before cleanly moving on to the next pre-baited stake.

3. Coastal Lantern & Dip Netting (The Catwalk Culture)

Further south, or directly within coastal openings, the casting mesh gives way to an entirely different style of night shrimping.

• South Florida Style: Netters line up along wet, concrete causeway catwalks under the cover of darkness. Bright lanterns are suspended directly over the moving tide, fully illuminating the surface. Anglers stand above the flow and use long-handled dip nets to cleanly pick off individual shrimp as they swim past.
• The North Florida Comfort Shift: In North Florida and local coastal inlets, netters use the same lantern-and-dip-net combination but skip the cold bridge structures entirely. Instead, they anchor their boats directly in the Intracoastal Waterway (ICW) or river mouths. Hanging lanterns over the gunwales lets you enjoy the same “phantom light” surface run from the dry, stable comfort of your own deck.

Mastering Your Electronics & Boat Handling

• Reading the Sonar Screen: Never throw your net blindly. A modern fish finder is one of your most valuable assets. On your screen, shrimp will show up as a thin line or a light, misty cloud hugging the bottom. If you see heavy arch markings suspended higher up in the water column, ignore them—those are just baitfish, and throwing will only waste your energy.
• Drifting vs. Anchoring: Unless the shrimp are incredibly concentrated or a dense crowd of other boats boxes you in, always choose drifting over anchoring. Drifting allows you to cover vast stretches of the channel edge. More importantly, moving with the tide minimizes “blowback”—when a fast-moving current pushes against your heavy net and forces the lead lines to cone and close prematurely before hitting the riverbed.
• The Wash Basin Tactic: Keep a heavy-duty, 3- to 4-foot-diameter plastic wash basin on your deck. Empty your loaded cast net directly into the tub. Because the basin holds a few inches of river water, it keeps the shrimp and small fish stable and alive while preventing them from scattering across your deck. This lets you clear your webbing and redeploy your net while the school is beneath you, leaving culling and sorting for when the action cools down.
• Timing the Tides: The best feeding and moving window occurs during the first hour after a major tide change. While both shifts will produce, an outgoing tide consistently outperforms an incoming tide.
• Know Your Legal Limits: The FWC legal bag limit on the St. Johns River is 5 gallons of heads-on shrimp per person or per vessel, whichever is less.

STRATEGIC HIGHWAY & LAUNCH ROUTES

• Gainesville to Green Cove Springs: North on Waldo Rd (US 301) through Waldo (CRITICAL: MIND THE LOCAL SPEED TRAPS!). At Starke, take SR 16 East to US 17. Launch at Governor’s Park Public Ramp (situated on the right side of US 17, 2–3 miles north of the SR 16 junction).
• DeLand to Welaka / Pomona Park (Southern Access): US 17 North completely past Crescent City into Pomona Park. Turn left at the main town stoplight onto CR 308B straight to the public ramp footprint. (Ramp sits 8 miles north of Lake George; run 1 mile south from the ramp to reach the condos and Turkey Island).
• I-95 to Palatka Launch: Take SR 100 West off I-95 (becomes SR 20). Take Route 17 North into East Palatka, cross the Memorial Bridge, go straight to 3rd Street, and hang a left to reach the Palatka City Dock & Boat Ramp.
• Jacksonville Area: Access the Trout River shipping channels via the launch grids near Seafarers Marina (455 Trout River Dr) to quickly scout deep current lines near Channel Marker 68.

⚡ Tidbits & Suggestions

• Sonar Screen: Shrimp show as a thin line or a light, misty cloud hugging tight to the bottom. Marks suspended higher up are baitfish—do not cast.
• Drift, Don’t Anchor: Drifting covers more ground and completely eliminates ‘blowback’ (when a strong current forces your net to cone and close prematurely before hitting bottom). Anchor only for heavy boat congestion or ultra-dense schools.
• The Daylight Net: Use a heavy 12-ft radius net with 3/8-inch square mesh (spreads to a 24-ft circle). Sinks rapidly to channel beds, traps everything, and can record limits in 3 to 4 casts. Use a small scout net to find them, and bring out the big daddy once you hit them.
• Night Shallow Baiting: Chum shallow flats with dry dog food, mark with a stake, let sit 1 hour. Approach in total silence by boat; an accurate throw clears the spot in a single cast before moving to the next stake.
• Tides & Limits: The first hour following a tide change is peak activity (outgoing tide outperforms incoming). The legal FWC bag limit is 5 gallons heads-on per person or per vessel, whichever is less. The system is legally CLOSED during April and May to protect the spawn.

Buy a cheap cast net! DO this.

Duct tape 5 inches above the lead line on both sides of the net. This prevents the net from closing too soon. You want it to sink open to trap the shrimp between the net and the river bottom.
