Magalloway River

The Magalloway is remote Maine brook-trout-and-salmon water at its purest — a cold, dam-controlled river spilling out of Aziscohos Dam through big-woods country on the New Hampshire line, with fly-fishing-only reaches that have protected wild brook trout and landlocked salmon for generations.

About this water

The Magalloway is remote Maine brook-trout-and-salmon water at its purest — a cold, dam-controlled river spilling out of Aziscohos Dam through big-woods country on the New Hampshire line, with fly-fishing-only reaches that have protected wild brook trout and landlocked salmon for generations. It runs on the Aziscohos release, so the flow you wade is what the dam sends down, and the water below the dam stays cold enough to hold real brook trout through the summer when lesser rivers fail their fish. This is conservation country: lightly developed, hard to reach, managed with care, and no place for trophy hero-talk. Walk in, fish stealthily, handle the brook trout — a heat-sensitive char — gently, and protect the autumn spawners. A remote native-brook-trout and salmon reach that anchors the wild end of the pack.
