The West Branch Penobscot River near Millinocket, Maine flows from Ripogenus Dam through rapids and pools to support possibly the best landlocked salmon fishing in the continental United States (alongside native brook trout). It offers year-round controlled cold-water conditions, productive insect hatches, and challenging riffles best fished with dry flies, streamers, and nymph rigs. During late summer, a fly-fishing-only stretch with tight bag and size limits highlights the region’s commitment to fishery conservation.
