What the Flats at Falmouth offer

The Flats at Falmouth are shallow saltwater grounds in Casco Bay where striped bass, bluefish, and flounder move through predictable channels and over sand bars, especially during the spring and fall migrations. The flats sit in 2 to 6 feet of water most of the year, making them accessible to waders, kayakers, and small boats without deep-water capability. The bottom is mostly sand and mud, with eelgrass beds that hold baitfish and attract larger predators.

Access is straightforward: you can launch from Falmouth Town Landing on Route 1 or wade directly from the beach at Mackworth Island State Historic Site, which sits just offshore. The flats are protected from Atlantic swells by the islands in Casco Bay, so conditions are usually calmer than open-water fishing. Tides matter here more than anywhere else on the Maine coast — the flats drain almost completely at low tide, and the best fishing happens during the two hours before and after high water.

Key Takeaways

  • The Flats at Falmouth hold striped bass and bluefish during spring (April–May) and fall (September–October) migrations, with summer flounder present June through September.
  • Water depth ranges from 2 to 6 feet, so wading and kayak fishing are practical options alongside small-boat access.
  • Tides control when the flats are fishable — low tide empties most of the area, and the best window is two hours before and after high water.
  • A Maine saltwater fishing license is required for anyone 16 and older; non-resident licenses are sold online and at tackle shops in Falmouth.
  • Falmouth Town Landing provides the main boat access, with parking and a concrete ramp suitable for kayaks and small skiffs.

Seasons and what species are present

Spring striped bass fishing runs from mid-April through May, when fish move north from wintering grounds and feed heavily in the shallows before heading upriver. Catches are most consistent in the first two weeks of May. Bluefish arrive slightly later, usually by late May, and remain through June. Both species feed on sand eels and silversides in the early morning and late afternoon.

Summer (June–August) is quieter for striped bass, but flounder fishing improves as water temperature rises. Flounder hold in the deeper channels and edges of the flats, where they ambush small fish and crustaceans. Fall brings the second major push: striped bass return in late August and peak in September and early October as they feed before migrating south. Bluefish are also aggressive in the fall, and the combination of two strong species makes September and October the most productive months overall.

Winter fishing is possible but unpredictable. Some striped bass remain in deeper pockets of Casco Bay, but the flats themselves are less productive. Most anglers focus on the warmer months.

How to reach Falmouth Town Landing and where to wade

Falmouth Town Landing is located on Route 1 (Main Street) in downtown Falmouth, about 20 minutes north of Portland. The facility has a concrete boat ramp, parking for roughly 30 vehicles, and a small dock. There is a parking fee — typically $5 to $10 per day, though rates change seasonally. The ramp is suitable for kayaks, canoes, and small skiffs; larger boats can launch but the flats themselves are too shallow for anything drawing more than 2 feet of water.

From the landing, paddle or motor northeast into Casco Bay toward Mackworth Island. The flats extend roughly 1 mile northeast of the island and are marked by shallow water and visible sand bars at low tide. If you are wading, Mackworth Island State Historic Site offers direct beach access. The island is open to the public, and you can park at the small lot and walk to the shore. Wading is best on the western side of the island, where the flats slope gradually and you can reach productive water in 10 to 15 minutes.

Regulations and licensing requirements

A Maine saltwater fishing license is required for anyone 16 years old and older. Non-residents can purchase a 7-day license or an annual license online through the Maine Department of Marine Resources website, or at tackle shops in Falmouth and nearby towns. Licenses are inexpensive — a 7-day non-resident license costs roughly $20 to $25, though prices vary by year.

Striped bass have a minimum size of 18 inches and a daily bag limit of one fish per angler in Maine. Bluefish have no size minimum and a daily limit of 10 fish. Flounder (summer flounder or fluke) must be at least 19 inches and the limit is 5 fish per day. Regulations can change, so check the current rules on the Maine DMR website before you fish.

Mackworth Island is a state historic site, and while fishing from the shore is permitted, camping and fires are not. Respect posted signs and stay on designated paths when walking to the water.

Tackle and techniques for the flats

Striped bass on the flats respond well to small topwater plugs (2 to 3 inches), soft plastic shads rigged on light jig heads, and live or dead sand eels. Bluefish are less picky and will hit most moving lures, but small metal spoons and poppers work reliably. Flounder require a different approach: fish live or dead baitfish (silversides, mackerel) on the bottom in the deeper channels, or use small soft plastics dragged slowly along the sand.

For wading, a 7- to 8-foot medium-power spinning rod with 10- to 15-pound braided line is standard. Kayak anglers often use the same setup but may prefer slightly lighter tackle. Bring polarized sunglasses — they let you see fish moving in the shallows and help you read the bottom structure. A tide table is essential; download one from NOAA or use a smartphone app so you know when the flats are fishable.

Fish the first two hours of the incoming tide and the hour before high water. During the outgoing tide, fish moves toward the deeper channels, and fishing slows. At dead low tide, most of the flats are exposed and unfishable.

Lodging and services in Falmouth

Falmouth is a small residential town with limited lodging. The nearest hotels are in Portland, about 20 minutes south, where options range from budget chains to upscale properties. If you want to stay closer, Freeport (10 minutes north) has a few inns and bed-and-breakfasts. Both towns have tackle shops, restaurants, and grocery stores.

Falmouth itself has a few small restaurants and a general store, but plan to drive to Portland or Freeport for a wider selection of food and supplies. Gas stations and ATMs are available in downtown Falmouth. If you are launching a boat, fill your tank before arriving at the landing — the nearest fuel dock is in Portland.

Frequently Asked Questions

Can I fish the Flats at Falmouth without a boat?

Yes. Wading from Mackworth Island State Historic Site is the most popular way to fish the flats without a boat. The walk to the water is short, and the gradual slope lets you reach productive water in shallow depths. Kayak fishing is also common and requires only a small vehicle to transport the kayak to the landing.

What time of year is best for striped bass?

May and September–October are the most consistent months. May offers the spring migration push, when fish are hungry and concentrated. Fall (September–October) is often better because both striped bass and bluefish are present and feeding aggressively before their winter migration.

Do I need a guide to fish the Flats at Falmouth?

No, but a guide can save time if you are unfamiliar with tides and bottom structure. Local guides operate out of Falmouth and nearby towns and can be found through tackle shops or online searches. If you fish on your own, bring a tide table and a map of Casco Bay, and plan to arrive at least 30 minutes before high tide.

What should I bring for a day of wading?

Bring waders or waterproof pants, polarized sunglasses, a tide table, your fishing license, a small tackle box with lures and extra line, and plenty of water. The flats offer no shade, so sunscreen and a hat are important. A waterproof bag for your phone and keys is also useful.

Are there restrictions on where I can fish in Casco Bay?

Most of Casco Bay is open to fishing, but some areas near islands are closed to protect nesting seabirds during breeding season (typically May–August). Check the Maine DMR website or ask at a local tackle shop for current closures before you fish.
