What You'll Find at Great Island

Great Island is a shallow, sheltered estuary in Old Saybrook, Connecticut, where the Connecticut River meets Long Island Sound. The island itself is mostly private residential land, but the surrounding waters—particularly the flats and channels—hold striped bass, bluefish, and weakfish. The real draw here is the shallow-water access: depths run 2 to 8 feet across most of the productive areas, which means you can fish from a skiff, kayak, or wade depending on the tide and your gear.

The fishing changes sharply with the tide. Rising water pushes baitfish into the shallows and brings larger stripers in behind them. Falling water concentrates fish in the deeper channels and holes. Most anglers target the slack water around the turn of the tide, when fish are less spooked by current and easier to locate. The season runs strongest from May through October, with June and September typically the most consistent months.

Key Takeaways

  • Great Island's shallow flats and channels hold striped bass and bluefish year-round, but May through October is when most anglers fish.
  • Tidal current dominates the fishing here—rising tide pushes fish into the shallows, and falling tide concentrates them in deeper channels.
  • You can access the water by launching a boat from Old Saybrook's public ramps or by kayaking from nearby access points, but there is no wading access directly from Great Island itself.
  • Shallow-draft boats, kayaks, and light tackle work best; the flats are too thin for deep-V hulls at low tide.
  • Connecticut's saltwater fishing regulations require a license for residents and non-residents alike, and striped bass have a 19-inch minimum size with a one-fish daily limit.

How to Get There and Launch

Great Island has no public boat ramp of its own, but Old Saybrook—directly across the water—has two public launch sites. The Old Saybrook Town Dock on Main Street offers limited parking and a concrete ramp suitable for trailered boats; arrive early, as spaces fill quickly on weekends. The Saybrook Point Marina also provides launch access for a fee and has more parking, though it caters mainly to overnight slip holders.

If you have a kayak or canoe, you can launch from the Connecticut River's public access points in Old Saybrook and paddle into the Great Island flats in 10 to 15 minutes. This is often the most practical route for light-tackle anglers targeting the shallows. Parking at river-access points is limited but usually available on weekday mornings.

The distance from either ramp to the productive flats is short—roughly a mile—so fuel consumption is minimal and the run is safe even in moderate chop. Plan for a 10-minute boat ride at idle speed to avoid spooking fish in the shallows.

Seasons and What to Expect

Spring (May–June) brings the first strong bite as water temperatures climb above 55 degrees. Striped bass move into the shallows to feed on spawning herring and sand eels. Bluefish arrive later in May and can be aggressive on topwater plugs. Tides are larger in spring, which means faster current and more dramatic depth changes—plan your fishing around slack water.

Summer (July–August) is the slowest season. Water temperatures exceed 75 degrees, and fish retreat to deeper channels and the mouth of the Connecticut River where cooler water flows in. Early morning and late evening are your best windows. Midday fishing is often unproductive. Weakfish show up in July and August but are less reliable than spring stripers.

Fall (September–October) is the second-best season. Water cools, baitfish concentrate, and both stripers and bluefish feed aggressively. September often produces the largest stripers of the year. October can be excellent but unpredictable—a cold snap can shut down the bite for days. By November, most anglers move to deeper water or stop fishing altogether.

Tackle and Techniques

Light to medium spinning rods (6 to 7 feet) work best on the flats. Baitcasters are less practical because the shallow water and frequent casts demand accuracy and speed. Use 15- to 20-pound braided main line with a 20- to 30-pound fluorocarbon leader to handle the abrasive bottom and occasional bluefish teeth.

Live bait—particularly live mackerel, herring, or mullet—is the most consistent producer. Fish them on a simple sliding sinker rig or under a popping cork in water shallower than 4 feet. Artificial lures work too: small topwater plugs (2 to 3 inches) excel early and late in the day, and soft plastics rigged on 1/4- to 1/2-ounce jigheads cover water quickly when you're searching for fish.

Wade fishing is possible in some areas at low tide, but the bottom is soft mud and silt—wear wading boots with good grip. Most anglers fish from a boat or kayak because it gives you mobility to follow the tide and reach the deeper channels where larger stripers hold.

Regulations and Licensing

Connecticut requires a saltwater fishing license for anyone 16 and older, whether you are a resident or visiting from out of state. You can purchase a license online through the Connecticut DEEP (Department of Energy and Environmental Protection) website or at tackle shops in Old Saybrook. A short-term license (7 days) is available if you are not a resident.

Striped bass have a 19-inch minimum size and a one-fish daily limit. Bluefish have no size minimum but a 10-fish daily limit. Weakfish must be 12 inches and have a 5-fish daily limit. These regulations change periodically, so check the DEEP website before you fish.

No special permits are needed to fish Great Island's public waters, but do not trespass on private land. The island itself is private; stay in the water and respect posted boundaries.

Tides, Currents, and Timing

The Connecticut River's tidal range at Great Island is roughly 3 to 4 feet, which sounds small but creates strong current in the narrow channels. Rising tide pushes water into the flats and shallows, concentrating baitfish and drawing stripers in to feed. Falling tide drains the flats and concentrates fish in the deeper channels and holes.

The slack water—the 20 to 40 minutes around the turn of the tide—is when most fish bite. During strong current, fish hold tight to structure and are harder to locate. Plan your trip to fish the slack water, not the peak of the tide. Tidal predictions for Old Saybrook are available through NOAA or most fishing apps; use them to time your launch.

Water clarity varies with rainfall and tide stage. After heavy rain, the Connecticut River pushes brown water into Great Island, which can shut down the bite for a day or two. Clear water (typical in summer and fall) makes sight-fishing possible on the flats, especially if you are poling a shallow-draft boat.

What Makes Great Island Different

Great Island is not a destination for deep-water trolling or offshore work. It is a shallow-water fishery that rewards patience, tide awareness, and light tackle. The fish here are not larger than what you will find elsewhere on the Connecticut coast, but they are abundant and willing to bite when conditions align. The proximity to Old Saybrook's ramps and the short run to productive water make it ideal for anglers with limited time or small boats.

The trade-off is that Great Island is crowded on weekends and holidays, especially in June and September. Weekday mornings are quieter and often more productive. The shallow water also means you must respect the bottom—running hard at low tide will strand you quickly. Local knowledge of the channels and holes is valuable; if you are new to the area, consider hiring a guide for your first trip.

Frequently Asked Questions

Do I need a boat to fish Great Island, or can I wade?

You can wade in some areas at low tide, but a boat or kayak gives you much better access to the productive channels and deeper holes where larger stripers hold. Kayaking is practical and affordable if you do not own a boat; the paddle from Old Saybrook to the flats takes 15 minutes.

What is the best time of day to fish Great Island?

Early morning (one hour before sunrise to two hours after) and late evening (two hours before sunset to dark) are most productive, especially in summer. Midday fishing is slow. Time your trip to fish the slack water around the turn of the tide, regardless of time of day.

Can I fish Great Island in winter?

Yes, but the bite is unpredictable and water temperatures drop below 40 degrees by December. Some stripers stay year-round, but most anglers move to deeper water or stop fishing. Winter trips require experience and proper safety gear.

What bait works best at Great Island?

Live mackerel, herring, and mullet are most consistent. Dead bait works but attracts fewer fish. Artificial lures—topwater plugs and soft plastics—are effective early and late in the day when fish are feeding actively.

How far is Great Island from other Connecticut fishing spots?

Old Saybrook is roughly 20 miles east of the Connecticut River's upper reaches and 15 miles west of the Rhode Island border. The Niantic River and Niantic Bay are 10 to 15 minutes by boat and offer similar shallow-water fishing for stripers and bluefish.
