The Rivière Saint-Maurice is one of Quebec's most storied rivers, flowing southward through the Mauricie region before emptying into the St. Lawrence River at Trois-Rivières. Stretching hundreds of kilometres through a landscape of boreal forest, rocky outcrops, and Canadian Shield geology, the Saint-Maurice offers a remarkably diverse fishery that draws anglers from across the province and beyond. From its upper reaches in the Mékinac territory to its lower stretches near Trois-Rivières, the river transitions through a variety of water types — including swift runs, deep pools, rocky rapids, and broad, slower-moving sections — providing habitat for an impressive array of species. The river falls within Fishing Zones 7 and 26 under Quebec's provincial regulations, and different sections of the river carry distinct rules that anglers must understand before wetting a line.
