Northwest River is a storied Atlantic salmon waterway located within the Terra Nova region of Newfoundland and Labrador, Canada. The river holds deep historical significance as a salmon fishery, having supported both commercial and recreational fishing for generations. The lower reaches of the river flow through a dynamic estuarine environment where freshwater meets the tidal influence of Cods Sound, creating prime habitat for sea-run Atlantic salmon. The river's character is shaped by its natural geography, including a waterfall that historically limited salmon migration to the lower 3.6 kilometers of the river until 1948, when modifications to the falls opened up additional upstream habitat for fish passage. Today, Northwest River is managed with a strong conservation focus, reflecting the broader challenges facing Atlantic salmon populations across Newfoundland and Labrador.
