108 kilometers long, the Coxipi River drains a watershed of over 1600 square kilometers in the heart of the Canadian Shield. Fed by Lake Poincarré, the river forms a large, elongated widening that takes the name of Lake Coxipi, then flows towards the Gulf of St-Laurent for a distance of 55 kilometers before emptying into it some fifteen kilometers from the village of Saint-Augustin.
The resinous forest gives the scenery a wild beauty. Several large land mammals inhabit the hinterland, including black bear, moose, woodland caribou, wolf, lynx, beaver and porcupine. Mink, hare and red fox are among the small mammals found in this pristine and authentic territory.
Tumultuous and splendid, the Coxipi River ends its descent to the sea with a long rapid interspersed with several pools. Salmon swim upstream for some 30 kilometers. The river is also frequented by brook trout. The Pourvoirie Saint-Augustin (outfitter), accessible by boat or floatplane, offers 13 kilometers of fishing.
