Mooselookmeguntic Lake

Mooselookmeguntic Lake sprawls across 16,359 acres of Franklin and Oxford county timberland, the largest lake in Maine's storied Rangeley chain. Sitting at roughly 1,467 feet of elevation, its basin is natural but dam-raised, its levels held by Upper Dam at the western outlet where Mooselookmeguntic spills down into Upper Richardson Lake. Everything about the place feels big: long wind-swept reaches, island-studded bays, and a shoreline that still reads mostly as forest. Among the Rangeley lakes, only Rangeley itself carries a more famous name, and many anglers would argue Mooselookmeguntic carries the better fishery.

What sets this lake apart is the wildness of its fish. Mooselookmeguntic shows no entries in the current MDIFW stocking report; its brook trout and landlocked salmon are self-sustaining populations, maintained by natural reproduction rather than the hatchery truck. In an era when most large New England salmonid lakes lean on annual plants, a 16,000-acre water running entirely on wild fish is a genuine rarity, and it shapes how the lake fishes. These are stream-bred fish that behave like it, keying on forage, moving with the seasons, and staging off tributary mouths when instinct calls them toward spawning water.

The lake's place in fly-fishing history is secured by a single fly. At Upper Dam, the pool at Mooselookmeguntic's outlet, Carrie Stevens tied the Grey Ghost in 1924, and the smelt-imitating streamer she created there went on to define an entire American school of fly design. The Upper Dam pool remains storied fly-fishing-only water, reached by a walk-in from the Mooselookmeguntic side, and fishing a Grey Ghost within sight of where it was invented is one of the great pilgrimages in the sport.

The fly angler's season follows the classic Rangeley rhythm. Ice-out brings the year's best big-fish window, with salmon and brook trout chasing bait in reachable water and big streamers doing the damage. Summer evenings turn to the surface, with Hexagenia and caddis activity in the coves around Toothaker Island drawing trout up in the fading light. Come September, brook trout stage off the Kennebago River outflow ahead of their spawning run, and streamer fishing sharpens again through the fall.

Access is honest and uncomplicated: a launch at Haines Landing in Oquossoc, canoe and float access with primitive campsites through the Stephen Phillips Preserve along the shoreline, and the walk-in at Upper Dam. Paddle out of a Phillips Preserve campsite at dawn with a box of streamers, and you are fishing the Rangeley country much as anglers did a century ago.

Mooselookmeguntic is a large, cold, north-country lake with a maximum depth of 139 feet against a mean of just 36, a profile that leaves enormous acreage of fishable shoal and mid-depth structure relative to its deep water. The state depth chart shows the character clearly: broad shelves and island-studded reaches surrounding deeper basins, rather than a single plunging trench. That mix suits a two-story fishery, with salmon working open water and the drop-offs while brook trout use shoreline structure, coves, and tributary influence.

As on the rest of the Rangeley chain, coldwater forage drives the gamefish, and smelt-imitating streamers have been the local currency since Carrie Stevens' day. Insect life earns its place too: the sheltered coves around Toothaker Island produce Hexagenia and caddis activity on summer evenings, and the shallower bays carry the chironomid, damselfly, and leech life typical of northern lakes. The lake stratifies in summer, pushing salmon toward the thermocline, while evening insect activity keeps brook trout honest in the coves.

The lake's size gives wind a long fetch, and conditions can build quickly on the open reaches. Small craft should plan routes along the shorelines and island lees rather than committing to long open-water crossings.
