What You'll Find at Lake of Isles

Lake of Isles is a small, shallow freshwater pond in Voluntown, Connecticut, tucked into the quiet corner where the Southeastern Planning Region meets the Rhode Island border. The lake sits at roughly 300 acres and runs no deeper than 15 to 20 feet in most places, making it a warm-water fishery that holds largemouth bass, pickerel, and panfish. The shoreline is mostly wooded and undeveloped, which keeps the water relatively clear and the fishing pressure light compared to the bigger lakes closer to the coast.

The pond's shallow character means it warms quickly in spring and summer, which brings the bass shallow and keeps panfish active all season. Weed growth is heavy in the warmer months—that's typical for a pond this size and depth—and the weeds hold fish reliably. If you're coming from the coastal lakes or the larger reservoirs, Lake of Isles will feel different: quieter, smaller in scale, and less crowded even on weekends.

Key Takeaways

  • Lake of Isles holds largemouth bass, pickerel, and panfish in a shallow, weedy pond that warms quickly and fishes well from late spring through early fall.
  • Public access is limited; you'll need to confirm current boat launch availability and parking before you go, as conditions can change seasonally.
  • The pond's shallow depth and heavy weed growth make it best fished from a small boat, canoe, or kayak rather than from shore.
  • Early morning and late evening are most productive, especially in summer when midday heat pushes fish deeper into the weeds and into shade.

Seasonal Patterns and What to Fish

Spring (April through May) is when Lake of Isles comes alive. As water temperatures climb into the 50s and 60s, largemouth bass move shallow to spawn, and pickerel become aggressive along the weed edges. Throw crankbaits, spinnerbaits, and soft plastics in the 3- to 5-inch range along any visible structure—fallen trees, weed lines, and the shallow bays on the north and south ends of the pond. Panfish (bluegill, pumpkinseed) also spawn in spring and will hit small jigs and live minnows in 2 to 6 feet of water.

Summer (June through August) shifts the bite deeper and earlier in the day. By mid-June, the pond's weed growth is thick, and fish move into the densest cover during daylight. Fish the early morning (first two hours after sunrise) and the last hour before dark. Work soft plastics rigged Texas-style through the weeds, or throw topwater lures at first light when bass are hunting in shallow water. Panfish remain active all day in deeper pockets within the weed beds.

Fall (September through October) brings a second window of excellent fishing. As water cools and weeds begin to die back, bass move more freely and feed aggressively. Crankbaits and spinnerbaits work well again, and you can fish a wider range of depths. Pickerel fishing improves noticeably in October as they prepare for winter.

Winter (November through March) is slow. The pond doesn't freeze solid reliably every year, but when it does, ice fishing for panfish is possible in the deeper holes. Most anglers skip winter here and return when the water warms.

Access and Launch Points

Public boat access at Lake of Isles is limited and informal compared to state-managed launches. The primary access point is near the dam on the southern end of the pond, where a small parking area and a basic launch ramp serve small boats, canoes, and kayaks. The launch is maintained by the town of Voluntown, and conditions—parking availability, ramp condition, seasonal closures—can vary. Call the Voluntown Parks and Recreation Department before you go to confirm the launch is open and accessible.

Shore fishing is possible but limited. The shoreline is mostly private property or wooded and difficult to reach. If you do fish from shore, stick to the public areas near the launch and respect posted property lines. A small boat, canoe, or kayak is the best way to fish Lake of Isles effectively, since the productive water is often 50 to 100 yards from shore.

The nearest town with services is Voluntown, about 3 miles south. There's no bait shop on the pond itself, so bring what you need or stop in Voluntown before you arrive. The drive from the coast (Groton, New London) is roughly 30 to 40 minutes depending on where you start.

Tackle and Techniques That Work

For largemouth bass, bring a medium-power spinning or baitcasting rod with 10- to 15-pound braided line. Soft plastics (4- to 6-inch worms, creature baits, and swimbaits) are the most versatile choice for a weedy pond like this. Texas-rigged plastics let you punch through dense cover without snagging constantly. Crankbaits in the 2- to 3-inch range work well in spring and fall when weeds are thinner. Spinnerbaits (1/4 to 3/8 ounce) are reliable along weed edges and around structure.

For pickerel, the same bass tackle works, but pickerel often prefer slightly larger baits and flashier presentations. A 1/2-ounce spinnerbait or a 5-inch soft plastic will draw strikes. Live shiners or small shiners on a simple rig (size 2 to 4 hook, split shot, and a bobber) are deadly in spring and fall.

Panfish respond to small jigs (1/16 to 1/8 ounce) tipped with a small piece of worm or a live minnow. A light spinning rod and 4- to 6-pound line make panfish fishing more enjoyable and let you feel the subtle bites. Bluegill and pumpkinseed will also hit small poppers and dry flies if you have a fly rod.

What to Expect: Weather and Conditions

Lake of Isles is exposed to wind from the northwest and west, which can make the pond choppy in the afternoon, especially in spring and fall. Morning calm is common, which is another reason to fish early. Summer afternoons can be hot and still, which pushes fish deep and makes fishing slow.

The pond is surrounded by forest, so it stays relatively cool even in midsummer. Mosquitoes can be heavy in June and July, especially near the shoreline. Bring insect repellent and consider fishing from a boat where the breeze helps keep them at bay.

Water clarity varies seasonally. Spring runoff can cloud the water for a few weeks, but by early summer the pond clears and remains relatively clear through fall. Algae blooms are possible in late summer but are not common. Check local reports before you go if you're concerned about water quality.

Nearby Water and Alternative Options

If Lake of Isles is crowded or not fishing well, several other ponds in the region are worth exploring. Pachaug Pond, about 10 miles south in Griswold, is larger and holds similar species. Ashland Pond, also in Voluntown, is smaller and shallower but can be productive for panfish. Both have public access, though you should confirm current conditions before you go.

If you want to fish moving water, the Pachaug River (which flows out of Pachaug Pond) holds smallmouth bass and panfish in its slower sections. The river is more technical to fish and requires wading, but it offers a different experience from pond fishing.

Regulations and What to Bring

Connecticut requires a fishing license for anyone 16 and older. You can purchase a short-term license (1 day, 7 days, or annual) through the Connecticut Department of Energy and Environmental Protection (DEEP) website or at most bait shops. Bass have a 12-inch minimum length and a 6-fish daily limit. Pickerel have a 15-inch minimum and a 10-fish daily limit. Panfish have no size limit and a generous daily limit, so you can keep as many as you want for a fish fry.

Bring sunscreen, water, and a hat—there's little shade on the water. A life jacket is required by law if you're in a boat, canoe, or kayak. A small cooler with ice keeps your catch fresh if you plan to keep fish. Polarized sunglasses help you see fish in shallow water and reduce glare off the water.

Frequently Asked Questions

Is Lake of Isles good for beginners?

Yes, if you have access to a small boat or kayak. The shallow water and abundant panfish make it forgiving for someone learning to fish. Bass fishing is also straightforward here—weeds hold fish reliably, so you don't have to search as hard. Shore fishing is harder because most productive water is far from land.

Can I fish Lake of Isles in winter?

The pond doesn't freeze solid every year, so ice fishing is not reliable. Open-water fishing in winter is slow because fish are deep and inactive. Most anglers fish elsewhere during the cold months and return to Lake of Isles in spring.

What's the best time of day to fish here?

Early morning (sunrise to mid-morning) and late evening (one hour before sunset) are most productive, especially in summer. Midday fishing is slow because fish retreat into deep weeds and shade. Spring and fall allow longer productive windows throughout the day.

Do I need a boat to fish Lake of Isles?

A boat, canoe, or kayak is strongly recommended. Shore access is limited and most fish are in deeper water away from the shoreline. A small rowboat or kayak is enough to reach productive water and explore the pond's structure.

Are there any fish-cleaning stations or facilities at the pond?

No. The launch area is basic—a ramp, parking, and not much else. Bring a cooler and ice if you plan to keep fish. You'll clean them at home or at your lodging.
