What the St. George River offers and where to fish it

The St. George River flows roughly 15 miles from the freshwater lakes around Liberty and Montville down to tidewater at St. George village, then another few miles to the Atlantic at Port Clyde. You get two distinct fisheries in one river: freshwater smallmouth bass and chain pickerel in the upper reaches, and striped bass that push upriver on the tide in the lower section. The river is narrow and winding, which means you can cover a lot of productive water without a long commute, and the banks stay relatively undeveloped compared to other coastal Maine rivers.

Access is the real advantage here. Unlike many Maine rivers that funnel you into a single public launch, the St. George has multiple entry points spread across its length, so you can pick a section that matches your target species and the time of year. Spring and early summer bring stripers into the lower river; summer and fall are prime for smallmouth in the upper half. The river also holds decent numbers of white perch, which most anglers overlook but which can be reliable when bass are slow.

Key Takeaways

  • The St. George River has two distinct sections: freshwater smallmouth and pickerel habitat upstream, and tidal striped bass water downstream near Port Clyde.
  • Public boat launches exist at Union Common (upper river) and at the Route 131 bridge near St. George village (lower river), with parking at both.
  • Stripers move into the lower river on incoming tide from April through June, and again in fall; smallmouth bite best in summer and early fall in the upper reaches.
  • The river is narrow and winding, so a 16- to 18-foot boat or canoe works better than a large center console, and you can cover a lot of water in a short trip.
  • White perch are abundant year-round and often bite when bass are inactive, especially around structure like fallen trees and old pilings.

Upper River: Smallmouth and Pickerel from Union to Montville

The freshwater section starts around Union Common, where a public boat launch sits on the north bank. This is the easiest access point and the one most locals use. From here upstream, the river winds through mixed forest and occasional pasture, with plenty of fallen trees, undercut banks, and shallow rocky areas. Smallmouth bass live throughout this section, and they respond well to topwater early in the morning and to soft plastics around structure in the afternoon.

Pickerel are just as common as smallmouth here, and they grow to respectable size—12 to 16 inches is normal. If you are throwing spinnerbaits or small crankbaits, expect to hook pickerel as often as bass. The upper river also has a population of chain pickerel that few anglers target deliberately, but they are there and they hit. Summer is the best season for the upper river; water levels drop enough to make the shallow sections fishable, and the bass move into deeper holes and along the banks.

Canoes and small johnboats are ideal here. The river is only 30 to 50 feet wide in most places, and fallen trees can block larger boats. If you have a 16-foot boat with a small outboard, you can run it, but you will spend time navigating around obstacles. Parking is available at Union Common, and the launch is free.

Lower River: Striped Bass and Tidal Water near St. George

The lower river, from roughly the Route 131 bridge downstream to Port Clyde, is tidal and holds striped bass that move in and out with the tide. This section is wider and deeper, and it opens up into St. George Harbor. Stripers enter the river on the incoming tide, especially during spring and early summer when they are moving up the coast. Fall also produces, though the window is shorter and the fish are often larger.

The Route 131 bridge is a focal point. Stripers hold in the current breaks and deeper pools around the bridge pilings, and they feed on herring and other baitfish that funnel through the narrow section. Fish the incoming tide for the best results; the outgoing tide can be productive too, but the incoming tide concentrates the fish. Early morning and the last two hours before dark are most reliable, though stripers will bite throughout the day if the tide is right.

A public launch exists near the Route 131 bridge on the east side of the river. Parking is limited but available. This is a good base for fishing the lower river and the harbor mouth. If you want to fish farther downstream toward Port Clyde, you can also launch from the Port Clyde area, though that is more of a harbor launch and less convenient for river fishing.

Seasonal patterns and timing

Spring (April through May) brings the first wave of stripers into the lower river. Water temperatures are still cold, and the fish are aggressive after winter. This is when you see the biggest stripers, sometimes in the 30- to 40-pound range, though 15 to 25 pounds is more typical. The bite is concentrated around the Route 131 bridge and the deeper pools just downstream.

Summer (June through August) shifts the focus to the upper river for smallmouth. Water levels drop, and the lower river becomes too warm and slow for stripers. Smallmouth move into deeper holes and along shaded banks. This is also when white perch become most active; they school in the deeper sections and can provide fast action when bass are sluggish. Pickerel remain consistent throughout summer.

Fall (September through October) brings stripers back into the lower river as water temperatures drop and baitfish move. The fall bite can be even better than spring, and the fish are often larger. Smallmouth in the upper river also bite well in fall, especially in September and early October before water temperatures drop too far. By November, both sections slow down significantly.

What to bring and how to fish

For the upper river, bring a 6- to 7-foot medium-action spinning rod and 8- to 10-pound monofilament or braided line. Topwater plugs, soft plastics in the 3- to 4-inch range, and small crankbaits all work. Spinnerbaits are excellent for covering water quickly and for triggering strikes from both bass and pickerel. Fish tight to structure—fallen trees, undercut banks, and rocky areas—and work slowly. The water is clear, so the fish can see your lure from a distance, but they also spook easily.

For the lower river, use a 7- to 8-foot medium-heavy rod and 12- to 15-pound line. Stripers respond to live herring, eels, and bunker if you want to fish bait, but they also hit large soft plastics (4 to 6 inches), topwater plugs, and small swimbaits. Cast around the bridge pilings and along the deeper banks. Work the incoming tide and focus on current breaks where baitfish concentrate. Stripers are less spooky than smallmouth, so you can use heavier tackle and make longer casts.

White perch in both sections respond to small jigs (1/8 to 1/4 ounce) tipped with live shiners or small soft plastics. They school, so once you find one, you will likely find more. Fish the deeper holes and around structure, and work the jig vertically or with short hops along the bottom.

Access and regulations

Maine requires a fishing license for anyone 16 and older. You can purchase a license online through the Maine Department of Inland Fisheries and Wildlife website or at most bait and tackle shops in the area. A seven-day license is available if you do not want to commit to a full year.

The St. George River is open year-round for bass and pickerel, though the best fishing is April through October. Striped bass have specific seasons and size limits that change year to year; check the current Maine saltwater fishing regulations before you go. White perch have no closed season and no size limit in most of Maine, so they are a good fallback when other species are slow.

Both public launches are free and open to the public. Parking is available at Union Common (upper river) and near the Route 131 bridge (lower river). Neither launch has facilities, so plan accordingly. The launches are maintained by the towns of Union and St. George, and both are accessible year-round, though winter ice can make them unusable.

Nearby alternatives if the St. George is crowded or slow

If the St. George is not producing, the Medomak River is only a few miles away and offers similar smallmouth and pickerel fishing in the upper reaches. The Damariscotta River, also nearby, has a larger tidal section and can hold stripers when the St. George is slow. Both rivers have public access and similar seasonal patterns.

For a different experience, Damariscotta Lake (freshwater) is close by and holds largemouth bass, chain pickerel, and white perch. It is larger than the St. George and offers more open water, which some anglers prefer. The Sheepscot River, to the south, is another option for stripers and smallmouth, though it is more developed and access is more limited.

Frequently Asked Questions

What is the best time of year to fish the St. George River?

April through May and September through October are best for stripers in the lower river. June through September is best for smallmouth and pickerel in the upper river. Summer can be slow for stripers because water temperatures rise, but white perch bite consistently year-round.

Do I need a boat to fish the St. George River?

A boat makes access easier, but you can wade fish some sections of the upper river, especially in summer when water levels drop. The lower river is tidal and deeper, so a boat is more practical there. Canoes and small johnboats work well for the entire river.

Where should I fish if I only have a few hours?

If you have limited time, fish the Route 131 bridge area in the lower river during incoming tide. This section concentrates stripers and white perch, and you can cover it thoroughly in two to three hours. For smallmouth, the upper river near Union Common is productive and close to the launch.

Are there any restrictions on boat size or motor type?

No specific restrictions exist for the St. George River itself, but the launches are designed for smaller boats. Anything over 20 feet may be difficult to launch or maneuver in the narrow upper sections. Electric motors are allowed and work well for the upper river because they are quiet and do not disturb the fish.

Can I fish the St. George River in winter?

The river is open year-round, but winter fishing is slow and the launches can be iced over. Most anglers fish April through October. If you want to fish in winter, check conditions at the launch before you go, and be prepared for cold water and short daylight hours.
