A Clear Border Lake in Southern Maine
Great East Lake sits on the Maine and New Hampshire border in Acton, in York County, about an hour northwest of Portland. The state line runs right down the middle of the water, so when you paddle from the eastern shore toward the western shore you cross from Maine into New Hampshire without ever leaving the lake. It is large, deep, and unusually clear, the kind of cold, clean water that makes southern Maine’s lakes worth the drive.
Most of the shoreline is lined with cottages and seasonal camps rather than wild forest. That gives the lake a settled, summer-community feel, but it also means public access is limited and most of the waterfront is private. We come here for the clarity, the room to spread out, and the fishing, which holds up well for a lake this close to the coast.
Almost all of the shoreline at Great East Lake is privately owned cottage frontage. Public access is essentially limited to the state boat launch, so respect private property and do not land on docks or beaches that are not yours. The lake is deep and the water below the surface layer stays cold all summer. Strong swimmers can tire fast in cold water far from shore, so wear a life jacket when paddling and keep an eye on weaker swimmers.
Swimming and Water Clarity
Great East Lake is one of the clearer lakes in southern Maine. On a calm day you can look down through the surface and see well into the water, and the bottom near shore is often sandy or gravelly rather than mucky. That clarity, combined with depth, is what draws families back to the same camps year after year.
Because the shoreline is almost entirely private, there is no large public swimming beach the way there is at a state park lake. Most swimming happens off private docks and cottage frontage. If you are renting a camp on the lake, you will have your own water access. Day visitors using the boat launch can swim near the launch, but there is no developed beach, so plan accordingly.
The surface layer warms up nicely by mid to late summer, comfortable for swimming on a hot day. Below that, the deep water stays cold year round, which is exactly what the lake’s salmon and trout need.
Late July and August give you the warmest surface water at Great East Lake. Early in the season the lake holds its spring chill well into June, so if swimming is the priority, aim for mid-summer when the top layer has had weeks of sun to warm up.
Boating and Paddling
Great East Lake is big enough for real boating. Powerboats, water skiers, and pontoon boats all use the lake through the summer, and there is room for everyone without the crush you find on the busiest lakes near Portland. The main basin opens up enough that wind can build a chop on a breezy afternoon, so smaller craft should watch the forecast.
For paddling, mornings are best. Get a kayak or canoe on the water early, before the powerboats start running, and you will have calm water and quiet coves to explore. Hugging the shoreline keeps you out of boat traffic and gives you the best look at the lake’s clear water. Just remember the shore itself is private, so paddle past the cottages rather than landing on them.
The wind on Great East Lake tends to pick up from midday into the afternoon. Paddlers and anglers in small boats should plan to be out early and back before the chop builds, especially when crossing the open main basin between the Maine and New Hampshire shores.
Fishing
Great East Lake is a strong coldwater fishery for southern Maine, and that is a direct result of its depth and clarity. The cold, well-oxygenated deep water supports species that struggle in shallower, warmer lakes nearby.
Landlocked salmon are the headline fish. They cruise the upper water column after ice-out in spring and again in fall, and drop deeper as the surface warms through summer. Trolling streamers and smelt-imitating lures near the surface is the traditional spring approach, then anglers switch to deeper presentations as the season goes on.
Lake trout, called togue here, hold in the cold deep water through the summer. This is downrigger and lead-core line territory, getting your offering down to where the togue stack up over the lake’s deepest holes. In winter, ice anglers target them with tip-ups.
Smallmouth bass round out the fishing and are the most accessible target for casual anglers. They hold around rocky points, drop-offs, and structure along the shoreline. Summer is prime smallmouth season, with good topwater action early and late in the day.
A Maine fishing license is required for anyone 16 and older. Because the lake straddles the state line, know which side of the water you are fishing, and check current MDIFW regulations before you go, since coldwater fisheries like this one often carry species-specific length and bag limits.
Getting There
Great East Lake is in Acton, in southwestern York County. From Portland, the drive is about an hour, heading inland and southwest toward the New Hampshire line. Cell service is generally good in the area, so GPS navigation to the lake is reliable.
The main public access is the state boat launch. This is the put-in for trailered boats, car-top kayaks, and canoes, and it is the practical starting point for any day trip since the rest of the shoreline is private. Parking at the launch is limited, so arrive early on summer weekends when the lot fills with anglers and boaters. If the launch lot is full, there is not much in the way of overflow parking, which is another reason to get there early.
When to Visit
Summer is the best overall season at Great East Lake. The surface water is warm enough for swimming by mid-summer, boating and paddling are in full swing, and the smallmouth fishing is strong. The trade-off is that summer weekends bring the most boat traffic and the tightest parking at the launch.
Spring is prime time for landlocked salmon, with fish near the surface after ice-out and far fewer boats on the water. The water is cold, so it is a fishing season more than a swimming one. Fall cools the lake back down and brings another window of good salmon and trout action along with quiet shorelines. Winter shifts the lake over to ice fishing for salmon and togue, for anglers prepared for cold-weather conditions.
FAQ
Where is Great East Lake?

Can you swim in Great East Lake?
Yes. The lake is deep, clean, and unusually clear, and the surface layer warms up comfortably by mid to late summer. There is no large public beach because the shoreline is almost entirely private cottage frontage, so most swimming happens off private docks or near the state boat launch.
What fish are in Great East Lake?
Great East Lake is a coldwater fishery with landlocked salmon, lake trout (togue), and smallmouth bass. Salmon are best near the surface in spring and fall, togue hold in the deep cold water through summer, and smallmouth fish well around rocky structure in summer.
Is there public access to Great East Lake?
Public access is limited. Most of the shoreline is privately owned cottage frontage, and the main public access point is the state boat launch. Parking at the launch is limited, so arrive early on summer weekends, and respect private property along the shore.
How cold is the water at Great East Lake?
The surface layer warms up for comfortable swimming in mid-summer, but the lake is deep and the water below the surface stays cold all year. That cold, deep water is what supports the salmon and lake trout fishery, and it means swimmers and paddlers should be cautious far from shore.
