About the Aroostook River
The Aroostook River rises in the commercial forest west of Ashland and runs east across the whole width of Aroostook County before crossing into New Brunswick at Fort Fairfield. The gauge near Masardis sits high in that run, above the farm country, where the river is still gathering water from the Machias, the St. Croix Stream and the other forest tributaries that give the upper valley its character. It is a big river by northern Maine standards and a remote one along most of its length.
Two fisheries share the drainage and they do not overlap much. The upper river and its tributaries hold wild brook trout, and those reaches are the reason anglers make the drive. Downstream of Ashland the river warms and broadens, and smallmouth bass become the practical target through the summer months, with muskellunge now established through the lower drainage and the New Brunswick reaches below it. Landlocked salmon show up seasonally where the cold tributaries enter.
The river is paddled as much as it is waded. A canoe covers the water between the few road crossings far more efficiently than walking does, and the stretch from Masardis down toward Ashland is the one most often floated. Access points are spread out, so a day here is usually planned as a float between two known landings rather than as a series of short walk-ins from the road.
Timing follows the snow. The upper Aroostook runs hard and cold into May, and the wild trout fishing is at its best once that water drops but before midsummer heat pushes fish into the tributary mouths. September brings the water back down to a good level and the trout back into the main river. The gauge at Masardis is the honest read on whether the float is worth the drive.
