The Southwest Miramichi River is a Canadian river in New Brunswick[1][2].
The river has its origin in Carleton County, at Miramichi Lake in the Miramichi Highlands (a part of the Appalachian Mountains). Its two branches join near the village of Juniper, NB. Flowing initially southeast through heavy forests, the Southwest Miramichi River is joined by the Taxis River at Boiestown, NB; then, begins to flow northeast. The river is tidal below Quarryville, NB. The Southwest Miramichi River joins the Northwest Miramichi River at Newcastle, NB to form the Miramichi River.
The river is noted for Atlantic Salmon fishing. It is navigable by canoe throughout much of its length. Nearly every bend in the river, for example Push and Be Damned Rapids, has a distinctive name reflecting the importance of the river to fishermen, canoeists, and lumbermen.
It is sometimes referred to as the "Main Southwest Miramichi River" to distinguish it from the Little Southwest Miramichi River, a smaller, more northerly branch of the Miramichi River system. The Mi'kmaq referred to the river as Lustagoocheech, meaning "good little river" for canoeing[3][4].
