About this water

The Northwest Miramichi drains the northern interior of New Brunswick before joining the main system at Doaktown. Larger water than the Southwest tributaries — wide pool-and-run structure, classic Atlantic salmon river form. Early-season fish rest in the lower pools before moving upstream as the water warms; by July, fresh grilse are running throughout the system. The pools are named and well-documented; this is a river with a long angling tradition and a guiding culture that has accumulated serious knowledge of where the fish hold and when they take. Atlantic salmon are managed under DFO conservation rules — mandatory catch-and-release of large (multi-sea-winter) salmon applies in most areas, with any grilse retention strictly limited by zone; check current regulations before fishing.
