Moosehead Lake

Moosehead Lake sprawls across 74,890 acres of the Piscataquis County highlands, a forty-mile inland sea studded with islands and framed by the cliff face of Mount Kineo rising straight out of the water. It is Maine's largest lake and, for a hundred and fifty years, its flagship coldwater fishery: sports have been riding trains and floatplanes to Greenville to chase landlocked salmon, togue, and brook trout since the heyday of the great sporting camps. That heritage is not a museum piece. The lake still fishes, and it still fishes best with a fly rod at the times and places it always has.

The engine of the fishery is rainbow smelt. Landlocked salmon, supported by annual stocking that augments a wild population, hunt smelt along shorelines and off tributary mouths from ice-out into June. Lake trout — togue, in the local vocabulary — are entirely wild here, self-sustaining since stocking ended in 1975, and grow fat in the cold water over the lake's 246-foot depths. The brook trout fishery is wild as well; hatchery brookie stocking was discontinued, and the squaretails an angler finds gulping mayflies over a midsummer shoal were all born in the watershed.

For fly anglers, Moosehead is really a collection of famous small places attached to an enormous lake. The Roach River delta at Kokadjo-side Spencer Bay, the Moose River mouth at Rockwood under Kineo, and the dam pool where the East Outlet of the Kennebec leaves the lake are classic smelt-streamer stations at ice-out and again in September, when salmon and brook trout stage before running the rivers. This is the fishery the Grey Ghost and its fellow Maine smelt patterns were built to imitate, and a stripped tandem streamer along a drop-off in early May is still the most reliable way to touch a Moosehead salmon.

Summer shifts the game toward the brook trout. Moosehead's shoals and coves produce genuine stillwater dry-fly fishing, with brookies cruising and gulping over rocky shallows on summer evenings, and a Hexagenia hatch that brings big fish to silty coves in late June and July. It is unusual, gulper-style fishing on a lake this size, and it rewards anglers willing to hunt calm water at dusk.

Moosehead demands respect. Forty miles of open water can build dangerous seas in wind, distances are long, and the best water is spread out. But the practical fly fishing concentrates at readable spots — river mouths, shoals, coves — served by good public launches at Greenville, Rockwood, Lily Bay State Park, and Seboomook. Pair it with the East Outlet of the Kennebec and the Roach River and you have the finest salmon-and-brookie circuit in the state.

Moosehead is a huge, cold, island-studded natural lake reaching 246 feet at its deepest, with an irregular shoreline of bays, narrows, and rocky points stretching some forty miles from Greenville to the Seboomook region at the north end. A summer thermocline sets up over the deep basins, sending togue and most salmon down out of practical fly range by July, while the extensive shoals, reefs, and cove shallows stay biologically busy all season and hold the wild brook trout that make Moosehead's summer surface fishing possible.

Rainbow smelt dominate the forage base and dictate the movements of salmon and lake trout: shallow and shoreline-oriented around the spring spawning runs into the tributaries, deep and scattered through midsummer, and back toward river mouths in fall. Insect life includes strong chironomid populations, caddis over the rocky shoals, and a notable Hexagenia hatch in the softer-bottomed coves in late June and July. The state's legacy survey map — a genuine fishery report with contours and management history — repays study for locating the shoals and drop-offs that concentrate fish on such a large lake.

Moosehead supports a long-running winter fishery, with anglers jigging and setting traps for togue, salmon, and cusk over the lake's deep basins once safe ice forms. The lake's size means ice conditions vary widely between bays and open reaches; check locally in Greenville or Rockwood for current ice and consult the Maine lawbook for the winter season dates and limits that apply.
