Kennebec River

The East Outlet of the Kennebec is where Maine's landlocked salmon reputation actually lives up to the postcards. It's a three-and-a-half-mile fly-fishing-only chute draining the east side of Moosehead Lake, running from the East Outlet Dam down to Indian Pond. Because it pulls cold water off the depths of the biggest lake in the Northeast, it holds in the 48–60°F band all season while the rest of Maine's freestones cook — and it carries wild, self-sustaining Moosehead-strain landlocked salmon that run 14–20 inches standard, with fish over 22 inches caught every year, plus wild brook trout in the 10–14 inch range. The salmon come and go from the lake: they push into the river chasing smelt in April and May, thin out in the July–August warmth, then flood back in September and October for the pre-spawn. That fall streamer window is the reason most people plan a trip here, with the spring smelt run a close second.

This fishes as a dam-controlled tailwater, and the single most important number is the East Outlet Dam release — and here's the catch for this page: that number is not a USGS gauge. Brookfield Renewable sets and posts it on SafeWaters (safewaters.com), and the East Outlet itself is ungauged live (the old USGS station 01040500 is discontinued). The nearest live flow gauges are downstream and on a different reach — 01042500 at The Forks and 01046500 at Bingham both reflect Harris Station generation, not the East Outlet schedule, so read them for the lower river, not for East Outlet wading. On the East Outlet, check SafeWaters before you drive: below roughly 1,800 CFS you can wade a lot of the named pools (the Dam Pool, Trestle Pool, and Beach Pool are the ones people name); at 2,000–2,500 you lose water and get pinned to the banks; by 3,000-plus you're shore-bound or in a boat. The drift-boat sweet spot is 1,800–2,400 CFS. This is powerful, rocky pocket water with Class II–III rapids between the pools — studded boots and a wading staff are not optional, and it earns an intermediate-to-advanced rating on higher water.

Two things confuse people about "the Kennebec below Harris Station." The premier fishing is the East Outlet above Indian Pond. Below Indian Pond, Harris Station Dam feeds the famous Kennebec Gorge — but that reach is managed for whitewater rafting, with daily 4,800–8,000 CFS generation releases from May through Columbus Day, so it's only a fishery on the calm early mornings and evenings before the water comes up (Northern Outdoors and Kennebec River Angler guide it as a remote, timing-dependent trip). Farther down, past The Forks where the Dead River comes in and on toward Bingham and Madison, the river warms and widens into more of a brown-trout and mixed-species river — good water in its own right (the walk-in brown-trout flat at "The Pines" in Madison is legitimately one of the best in the state), but a different fishery than the cold salmon water up top.
