Moosehead Lake Outlet

This is the upper Kennebec River, just below its birthplace at the outlet of Moosehead Lake. Moosehead is just beyond the railroad bridge. Moosehead is Maine's largest lake. Sebago is Maine's second largest lake.

Like Sebago Lake, the outlet of Moosehead Lake has a dam to control downstream flows and lake levels.

Like Sebago Lake, Moosehead Lake has a large population of lake-dwelling Atlantic salmon which attract thousands of anglers to the lake each year.

Like Sebago Lake's outlet, the upper Presumpscot, Moosehead's outlet, the upper Kennebec, is a very popular destination for trout and salmon anglers.

But unlike Sebago Lake, Moosehead Lake has a working fishway for landlocked salmon at its outlet, operated for decades by the Maine Department of Inland Fisheries & Wildlife.

Salmon and trout can move freely between Moosehead Lake and upper Kennebec
Salmon and trout are barred from moving between Sebago and the upper Presumpscot.


The Moosehead Lake Outlet fishway is operated specifically to allow adult landlocked salmon from Moosehead Lake to drop down into the Kennebec River to spawn; to allow wild, juvenile salmon from the river to enter Moosehead Lake to grow to adulthood.

Years of study by state fisheries biologists indicate that nearly all adult salmon which drop out of Moosehead Lake to spawn in the upper Kennebec return to the lake within a year after spawning. They are not "lost" from lake and provide angling opportunities during their time in the river and in the lake.

Years of study by state fisheries biologists indicate that most of the wild salmon born in the upper Kennebec by parents from Moosehead Lake swim upstream into the lake during the summer of their second or third year in the river, or at about 6-8 inches long, and remain in the lake until they reach spawning age.


Upper Kennebec River

This is Paul Johnson, the state's senior fisheries biologist for the Moosehead Lake region, at the "Beach Pool" on the upper Kennebec River, a mile or so below the Moosehead Lake outlet dam and fishway.

Paul is explaining a cooperative project between his department and the Kennebec Water Power Company to improve spawning habitat for the landlocked salmon of Moosehead Lake that use the lake's outlet for spawning.

The project expanded and deepened an existing salmon spawning site that often dried up during low winter flows. Downstream, workers cleaned out and expanded a side channel on the river to create quality growing habitat for newly hatched wild landlocked salmon.

A few weeks after this photo was taken in fall, 1998, more than 50 landlocked salmon from Moosehead Lake spawned in the shallows where Johnson is standing -- the most he had ever seen.

Johnson's goal is to improve spawning and growing conditions in the upper Kennebec so that stocking of landlocked salmon in Moosehead Lake will no longer be necessary.
