Androscoggin River

Fishing the Androscoggin River

The Androscoggin River below the dam in Errol, NH is one of New England’s finest rivers for landlocked salmon and brook trout. The Androscoggin flows out of Lake Umbagog on the New Hampshire – Maine border. Known for its alder fly hatch that occurs in the latter part of June, the river flows along the side of New Hampshire’s Route 16 from Errol to Berlin. The Andro is 30 minutes east of the Connecticut River via Rte 26.

Best Time to Fish

The river starts fishing in mid-May and fishes great through mid- July.  The dam in Errol is not a tailwater dam so the river water tends to heat up as summer progresses. The lake above, Umbagog, is shallow in many places which help to raise river temps in the summer. As the water cools in the fall, the fishing turns on again.  Starting in mid-September, the river fishes great until the season’s end on October 15th.

The Androscoggin is a good sized, New England river and is best accessed by drift boat, raft, kayak or canoe. There are few safe areas for wading. The “Andro” is located along route 16 from Errol to Gorham NH.
