The Jock River winds through the Ottawa region of Ontario, Canada, offering a surprisingly diverse urban and semi-rural fishery that punches well above its weight in terms of species variety and quality. Flowing through a landscape characterized by a mix of wetlands, cropland, woodland, and settlement areas, the river supports a rich fish community of 18 or more species spanning warm and cool water recreational fish. The Richmond Fen area — a Provincially Significant Wetland and Area of Natural and Scientific Interest — is among the notable natural features along the river's corridor, contributing to the ecological richness that makes this waterway productive for anglers. Despite its accessibility from Ottawa, the Jock River remains an underappreciated gem that rewards those willing to explore its varied stretches.
