The Mingan is a bountiful river that flows southward through the Canadian Shield, rising 579 meters above sea level. Including its tributaries, it flows for a total of 117 kilometers, and has a watershed that covers more than 2,000 square kilometers. The mouth of the river is located near the Mingan Native community along the shores of the Gulf of St. Lawrence, 12 kilometers east of Longue-Pointe-de-Mingan.
This beautiful river is embedded in the middle of a granitic landscape, where it flows among flourishing firs and spruce trees. The area has always traditionally been an important hunting and fishing ground for the Innu people. Europeans began fishing for Atlantic salmon here in the early the 19th century.
The Mingan River runs fairly straight from its source, only meandering down two large curves before opening out into a wide estuary. In part of the lower section, the river cuts through eroded clay cliffs and sand banks. When the river flow is lower, salt water from the Gulf can rise up more than a kilometer into the Mingan. There is one massive waterfall located about nine kilometers up from the mouth, and many more rapids dot the course of the river further north.
This salmon fishing paradise is also home to rainbow smelt, brook trout and lake sturgeon, as well as northern pike, whitefish and lake trout. The river bed is mostly composed of gravel, pebbles and cobbles. The Pourvoirie du Lac Allard et Rivière Mingan inc, an outfitter with no exclusive rights, is responsible for managing the fishery on part of the river.
