What Mere Point Bay Offers

Mere Point Bay is a shallow, protected saltwater estuary in Brunswick, Maine, where the New Meadows River meets Casco Bay. The bay holds striped bass, flounder, and seasonal mackerel, with depths ranging from 6 to 20 feet across most of the fishing grounds. The water stays relatively calm because the bay opens to the Atlantic only through a narrow mouth, making it accessible to small boats and kayaks even when offshore conditions are rough.

The bay's appeal lies in its proximity to Portland and its mix of sand flats, rocky points, and eelgrass beds—each holding different species at different times of year. Summer brings the most activity, when striped bass move into the shallows to feed. Fall can be excellent for mackerel. Winter fishing is possible but limited by weather and fewer active fish. Spring sees the return of migrating stripers and the beginning of flounder season.

Key Takeaways

  • Mere Point Bay is a shallow estuary near Brunswick where striped bass, flounder, and mackerel are the primary targets, with summer offering the most consistent fishing.
  • Access is by private boat or kayak launched from Mere Point Road or nearby public ramps; there is no shore fishing access to the main bay.
  • Maine saltwater fishing requires a license for anyone 16 and older, purchased through the Department of Inland Fisheries and Wildlife.
  • Striped bass have a 19-inch minimum size limit and a two-fish daily bag limit; flounder and mackerel have separate regulations that change annually.
  • Tides matter significantly in this shallow bay—slack water and incoming tide typically produce better fishing than outgoing water.

Seasons and What Fish Are Active

Summer (June through August) is peak season for striped bass in Mere Point Bay. Stripers move into the shallows to hunt baitfish, particularly sand eels and silversides, and will take live bait, soft plastics, and small plugs. Water temperatures in the 60s and 70s trigger aggressive feeding. Early morning and late evening are most productive, though overcast days can produce all day.

Fall (September and October) brings mackerel into the bay as they migrate south. Mackerel are less selective than stripers and will hit small metal jigs and spoons quickly. Flounder also remain active through October in the deeper holes and channels. Water temperatures drop into the 50s, which slows activity but can concentrate fish in specific zones.

Spring (April and May) sees striped bass returning from their winter grounds, though the fishing is less predictable than summer. Flounder season opens in May in most of Maine's coastal waters, and Mere Point Bay's sandy bottom supports a resident population. Winter fishing is possible but weather-dependent; some anglers target flounder in the deeper channels, but ice and rough conditions make access difficult.

How to Access the Bay

The primary launch point is Mere Point Road in Brunswick, where a small public parking area and boat ramp provide access to the bay. The ramp is maintained by the town and is free to use. It accommodates trailers and has enough space for several vehicles, though it fills on summer weekends. The ramp is concrete and in reasonable condition, though it can be soft at the edges during spring runoff.

Kayak anglers can launch from the same ramp or from the beach area adjacent to it. The bay is shallow enough and protected enough that kayaks are practical for reaching most fishing zones, though paddlers should be aware of tidal currents near the mouth and plan launches around tide times. No commercial guide services operate exclusively in Mere Point Bay, but several Brunswick-area charter captains fish the bay as part of their regular rotation.

There is no shore fishing access to the main bay itself. The shoreline is privately owned, and the only public access is by water from the Mere Point Road launch. Anglers without boats can fish the New Meadows River upstream from the bay, where some public access exists, though the fishing is different and less productive than the open bay.

Regulations and Licensing

Maine requires a saltwater fishing license for anyone 16 years old and older. Licenses are sold by the Department of Inland Fisheries and Wildlife through their website, by mail, and at authorized retailers throughout Maine. A three-day license costs less than a full-year license and is useful for short trips. Licenses are checked by Maine Marine Patrol, which patrols Casco Bay regularly.

Striped bass in Maine have a 19-inch minimum size limit and a two-fish daily bag limit per angler. Fish under 19 inches must be released immediately. Flounder (also called winter flounder) have a 12-inch minimum and a 10-fish daily bag limit, though these numbers can change annually—check the current regulations before you fish. Atlantic mackerel have no size minimum and a 25-fish daily bag limit.

Regulations change each year, and some are adjusted mid-season based on stock assessments. The Department of Inland Fisheries and Wildlife publishes a saltwater fishing guide each spring; download it or request a printed copy before your trip. Violations carry fines and can result in license suspension.

Tackle and Bait That Works

For striped bass, live bait is highly effective: sand eels, silversides, and mackerel all work well. Use a simple rig with a single hook and a small weight to keep the bait near the bottom in 10 to 15 feet of water. Soft plastic baits—4 to 6 inch shads in natural colors—are equally productive and easier to cast repeatedly. Small plugs (2 to 3 inches) that mimic baitfish also draw strikes, particularly in early morning.

Flounder respond to live sand eels and small shiners fished on the bottom. A two-hook rig with a spreader bar keeps both baits working at once. Flounder are less aggressive than stripers and may mouth a bait before taking it fully, so use a slow retrieve and watch your line for subtle takes. Mackerel will hit small metal jigs (1/2 to 1 ounce) and spoons cast and retrieved quickly through schools.

Bait is sold at tackle shops in Brunswick and Topsham, including local retailers that stock sand eels and shiners year-round. Bringing your own bait from home is also common; many anglers catch their own silversides in shallow water the day before fishing.

Tides and Timing

Tides in Mere Point Bay swing 8 to 10 feet between high and low water, and tidal current is the single most important factor in fishing success. Slack water—the brief period when current stops between incoming and outgoing tides—is when fish feed most actively. The incoming tide (flood) is generally more productive than the outgoing tide (ebb), particularly in the shallower flats where stripers hunt.

Plan your launch around the tide table for Brunswick. The National Oceanic and Atmospheric Administration (NOAA) publishes tide predictions for Casco Bay and nearby reference stations; use these to time your fishing around slack water and the incoming tide. A two-hour window around slack water is often enough to catch fish, though longer periods of incoming tide can produce throughout.

Water temperature also matters. Check the temperature before you go; stripers are most active when water is between 60 and 75 degrees Fahrenheit. In summer, early morning and evening fishing is often better than midday because the water is cooler and fish are more active. In spring and fall, midday can be productive as water warms slightly.

Hazards and What to Watch For

Mere Point Bay is shallow, and running aground is the most common problem. Stay in marked channels and use a depth finder if your boat has one. The bay bottom is soft mud and sand, so grounding is usually not dangerous, but it can leave you stranded until the tide rises. Avoid the shallower flats (under 4 feet) unless you are in a kayak or very shallow-draft skiff.

The mouth of the bay opens to Casco Bay, where ocean swells can build quickly if weather turns. Check the marine forecast before launching, and stay inside the bay if conditions are rough. Fog is common in spring and early summer; carry a compass and know how to navigate by landmarks if visibility drops.

Boat traffic increases on summer weekends, particularly near the launch ramp. Give other boats room, and be aware that jet skis and recreational boats may not be watching for fishing boats. Wear a life jacket at all times, and carry a radio or cell phone for emergencies.

Frequently Asked Questions

What size boat do I need to fish Mere Point Bay?

A 16 to 18-foot center console or open boat is ideal, but anything 14 feet or larger will work. Kayaks are also effective for reaching shallow flats. The bay is protected and shallow, so you do not need a large, ocean-capable boat. A small outboard or electric trolling motor is sufficient for moving between fishing zones.

Can I fish Mere Point Bay in winter?

Yes, but conditions are difficult. Flounder remain in the deeper channels and can be caught through December, but ice, cold water, and rough weather limit access. Most anglers fish the bay from April through October. Winter fishing is best left to experienced boaters with proper cold-weather gear.

Do I need a guide to fish Mere Point Bay?

No. The bay is small, well-marked, and easy to navigate. If you have a boat and a saltwater license, you can fish on your own. Guides are available through charter services in Brunswick if you prefer instruction or want to learn the bay quickly, but they are not necessary.

What is the best time of day to fish?

Early morning (sunrise to mid-morning) and late evening (two hours before sunset to dark) are most productive for striped bass. Flounder and mackerel are less time-sensitive and can be caught throughout the day, though slack water and incoming tide matter more than the hour.

Where can I buy a Maine saltwater fishing license?

Licenses are sold online through the Maine Department of Inland Fisheries and Wildlife website, by mail, and at tackle shops and sporting goods retailers throughout Maine. A three-day license is the shortest option and costs significantly less than an annual license.
