The narrow Rivière Kécarpoui, whose name means "porcupine river" in the Innu language, flows for 27 kilometers before emptying into the Gulf of St-Laurent west of the village of Saint-Augustin. It drains a watershed of 676 square kilometers, in a majestic setting dominated by conifers.
A paradise for wildlife, the river's many islands and islets near its mouth support colonies of seabirds. The land mammals most often found along the river are typical of the region. Black bear, moose, woodland caribou, wolf, fox, lynx and, in terms of small fauna, muskrat, mink, otter and porcupine dominate the ecosystem.
Salmon swim 19 kilometers up the Kecarpoui River on a bed of medium-sized rocks. Their average weight varies from 2.2 to 4.8 kilograms. A non-exclusive outfitting operation welcomes anglers and nature lovers to this haven of peace on a human scale, nestled in a setting of disproportionate proportions.
