The Ottawa River is one of eastern Canada's most storied and productive fisheries, flowing along the western edge of Quebec through communities like Gatineau and Hawkesbury before eventually connecting with the St. Lawrence system. Stretching across a vast watershed, this major river system supports an extraordinary diversity of fish — more than 85 species have been documented in its waters — making it a destination that rewards anglers of virtually every discipline. From trophy muskellunge lurking in deep holes to abundant walleye stacked on current breaks and hard-fighting smallmouth bass working rocky structure, the Ottawa River offers world-class angling in a setting that blends urban accessibility with genuine wilderness character. The river's broad, island-studded reaches, side channels, and varied structure create a mosaic of habitat that sustains this remarkable fishery year-round.
