Square Lake
Square Lake: A Large Water Landscape in the Fish River Chain

Discover
Square Lake brings a sense of scale to northern Maine’s Fish River chain. The state fisheries survey identifies it as the largest lake in that connected system, recording 8,150 acres and a maximum depth of 122 feet. Its largely undeveloped setting gives the water a substantial presence in the landscape. Plan a visit around the lake itself, with enough time to appreciate the shoreline and the space between points, rather than making a crossing simply to reach somewhere else.
Burnt Landing provides an established starting point. The county tourism route published on Maine Trail Finder approaches it from Route 161, following local and gravel roads to Square Lake Road. Its directions identify a welcome sign bearing the name Muscovic at the landing. Check the route and road conditions before setting out, and make the arrival part of your planning. The last portion of the drive deserves attention, especially when you are carrying a boat and supplies.
The lake’s connecting waters also explain its fisheries. The historical survey describes Eagle Lake Thoroughfare, the outlet, as important salmon spawning and nursery habitat. Other connections and tributaries contribute too, while smaller inlets provide spawning areas for brook trout. Smelt have their own significance, both as a fishery and as food for salmon and trout. These relationships make the lake an ecological meeting place, with the shore and moving water supporting what happens in the open basin.
The same Maine Trail Finder route continues toward Eagle Lake through a lengthy thoroughfare, but it is a substantial one-way outing with different planning needs from a local paddle. Its description cautions that shallow sections and short rips affect passage, with conditions differing between craft and water levels. It also warns that strong winds can make Square Lake extremely rough. Choose a route and turnaround that fit your party, and preserve the option to wait or shorten the day.
Vaughn Hardacker’s original 2016 essay brings a local voice to that warning. He recalls personally experiencing how quickly Square could change from a smooth surface to waves large enough to overwhelm many boats. His affection for the lakes sits alongside that respect for their force. Read his account as a reminder to pay close attention to conditions, while arranging any trip with present-day information and a realistic assessment of your own skills.
Hardacker also describes the appeal of a remote overnight stay, recalling a view of the Milky Way at Limestone Point under a clear sky. Treat that as a historical personal perspective, and confirm current campsite arrangements before planning to land or camp. The atmosphere he values is the chance to remain in the landscape long enough for daylight to give way to something different.
An outing does not need to span the lake to feel complete. A wooded point, the changing shape of the shore or a comfortable pause can give it a clear focus. Choose the return while everyone still has energy in reserve, leaving time to enjoy the lake again on the way back.
