The Androscoggin below Errol Dam is northern New Hampshire's big-river trout and salmon water — a wide, cold, dam-influenced freestone running out of Umbagog through the Thirteen Mile Woods, holding native brook trout, landlocked salmon, and browns and rainbows in fast, broken, wadeable water. The dam at Errol steadies the top of the river and keeps it cool, and the salmon move up through the rips chasing smelt while the brookies and rainbows hold in the pockets and seams. It's a float-and-wade river in moose-and-loon country, fished with streamers and big attractor dries, less technical than the southern tailwaters but every bit as cold and serious about its fish. A strong northern New Hampshire river that keeps its salmon-and-brook-trout identity on honest dam-influenced freestone water.
