What You'll Find at Great Island

Great Island is a shallow-water fishery tucked into the Connecticut coast near Old Lyme, where tidal flats and narrow creeks hold striped bass and bluefish on the push and pull of the tide. The island itself is mostly private, but the surrounding water—especially the flats on the eastern side and the creeks that drain into the Sound—holds fish in predictable patterns. You're fishing water that rarely exceeds eight feet, often much less, which means sight-casting and reading the bottom are part of the game here.

The real draw is the seasonal movement. Spring brings stripers moving through on their way north; summer holds resident fish in the deeper creeks; fall brings aggressive feeding as baitfish schools tighten up. Winter fishing is possible but thin. The access points are limited and require local knowledge—there's no public boat launch on the island itself, and much of the shoreline is private. But if you know where to launch and how to read the tides, Great Island rewards the effort.

Key Takeaways

  • Great Island's shallow flats and tidal creeks hold striped bass and bluefish, but you need a boat or kayak to reach the best water—there is no public shoreline access on the island itself.
  • Spring and fall are the strongest seasons; summer holds fish in the deeper creeks, and winter fishing is sparse.
  • Tidal movement is everything here—fish move onto the flats on the rising tide and retreat to deeper channels on the drop, so timing your arrival matters more than the time of day.
  • Launch from Lyme town ramps or nearby Old Lyme access points, then motor or paddle east toward the island's flats and the creeks that drain into Long Island Sound.

Seasonal Patterns and What Fish to Target

Spring (April through May) brings migrating striped bass moving through the Sound on their way to spawning grounds. These fish are hungry after winter and will hunt baitfish on the flats during the rising tide. Bring small plugs, soft plastics in the three- to four-inch range, and be ready to cast to moving water rather than static structure. The bite is often best in the two hours before high tide.

Summer (June through August) slows the action on the flats themselves, but the deeper creeks—especially those on the western side of the island—hold resident stripers that have settled in for the season. Fish these channels at dawn and dusk, when light is low and stripers move shallow to feed. Bluefish show up in July and August, often chasing baitfish in the same creeks. They're aggressive and will hit larger plugs and metal.

Fall (September through October) is when Great Island comes alive. Baitfish schools compress as water cools, and stripers and bluefish feed heavily in preparation for winter. The flats produce consistent action during the rising tide, and the creeks hold fish throughout the day. This is the season to fish multiple tides if you can—morning and evening bites are both strong.

How to Read the Tides and Fish the Flats

Great Island's flats are only productive on the rising tide. As water pushes in from the Sound, stripers move onto the shallow bottom to hunt. The sweet spot is usually the first two hours of the rising tide, when water depth is still manageable but deep enough for fish to move freely. Once the tide peaks and begins to fall, fish retreat to the deeper creeks and channels—fishing the flats on the outgoing tide is usually a waste of time.

The creeks that drain the island work the opposite way. On the falling tide, water rushes out through these channels, concentrating baitfish and stripers in a smaller space. Fish the creek mouths and the deeper sections as the tide drops, especially in the hour or two before low water. The current creates a natural funnel, and stripers will position themselves to intercept baitfish being swept seaward.

Depth is your constant reference. Carry a depth finder or learn to read the water by eye—sandy bottom looks lighter, mud and grass darker. Stripers on the flats often hunt in two to four feet of water. If you're in shallower than two feet, you're likely spooking fish. If you're deeper than six feet, you've moved off the productive zone.

Access Points and How to Launch

There is no public launch on Great Island itself. Your best options are the town ramps in Old Lyme and nearby Lyme. The Old Lyme town ramp (located near the Connecticut River mouth) gives you direct access to the Sound and a reasonable run to Great Island's eastern flats—roughly a mile or so depending on which part of the island you're targeting. Launch fees vary; check with the town before you go.

If you have a kayak or small skiff, the Lyme town ramp offers another route, though it's slightly farther from the island. Both ramps are busy during peak season, so arrive early if you're fishing a weekend. Parking can be tight, especially in summer. If you don't have your own boat, some charter captains in the area run trips to Great Island and the surrounding flats—ask at local tackle shops for current recommendations.

Once you're on the water, navigation is straightforward but requires attention. The island is clearly visible from the Sound, and the flats on the eastern side are obvious once you're close—they're the shallow, light-colored water. Stay aware of other boat traffic, especially on weekends. The creeks are narrow in places, and running at speed in shallow water is how people damage props and get stuck.

Tackle and Bait Choices

For the flats, light to medium spinning tackle works best. A six- to seven-foot rod with eight- to ten-pound braid gives you the sensitivity to feel the bottom and the distance to reach cruising fish. Stripers on the flats respond well to small plugs (two to three inches), soft plastics rigged on light jig heads, and topwater lures during low-light periods. Bluefish want something with more flash and size—try four-inch soft plastics or small metal spoons.

Live bait is effective if you can keep it alive in the boat. Mackerel and herring work, but they're harder to find than they used to be. If you go the live-bait route, use a simple rig: a single hook through the nose or back, minimal weight, and let the bait swim naturally. Dead bait is less effective on the flats but works in the creeks, especially on the falling tide when current does the work for you.

Bring more than one rod. If you're sight-casting on the flats, having a second rod rigged with a different lure type lets you switch quickly without losing time. The bite window on the flats is often narrow, and changing lures mid-session can mean the difference between a few fish and none.

What to Watch Out For

Shallow water means shallow-draft hazards. Rocks, sandbars, and submerged debris are real. Run at idle speed in water shallower than four feet, and use your depth finder or polarized sunglasses to spot obstacles before you hit them. The flats look clear from a distance, but they're not. Respect the bottom.

Weather changes fast on the Sound. A calm morning can turn choppy by midday, especially in summer when afternoon sea breezes build. Check the forecast before you launch, and don't stay out if conditions are deteriorating. The flats offer no shelter, and a small boat in rough water is a bad combination.

Crowds are increasing. Great Island is becoming more popular, and weekends can be busy. If you want solitude and consistent fishing, fish weekdays or early morning. The fish don't care about crowds, but they do care about noise and commotion—a quiet approach catches more than a loud one.

Frequently Asked Questions

Can I fish Great Island from shore?

Not really. The island itself is private, and the surrounding flats are too far from public land to reach on foot. You need a boat or kayak to fish the productive water. If you don't have one, look into charter services or ask at local tackle shops about shared-boat options.

What's the best time of year to fish Great Island?

Spring (April-May) and fall (September-October) are strongest. Summer holds fish but the action is slower and more concentrated in the creeks. Winter is possible but sparse. If you can only make one trip, go in fall when the bite is most consistent.

Do I need a Connecticut fishing license?

Yes. Connecticut requires a saltwater fishing license for anyone 16 and older. You can purchase one online through the Connecticut DEEP website or at most tackle shops. Licenses are inexpensive and valid for the calendar year.

How shallow can I run my boat on the flats?

Two feet is about the minimum for most boats without risking damage. Kayaks and very shallow-draft skiffs can go shallower, but you'll spook fish in water that shallow anyway. Three to four feet is the sweet spot—deep enough to avoid obstacles, shallow enough to find feeding stripers.

What do I do if I get stuck on a sandbar?

Don't gun the engine—that digs you in deeper. Tilt the motor up, use a pole or paddle to push off, or wait for the tide to rise. If you're truly stuck, call for a tow. It's worth the cost to avoid prop damage. Prevention is easier: run slow in shallow water and watch your depth finder.
