Rivière des Îlets (Gouffre River tributary)
The Rivière des Îlets is a tributary of the southern bank of the upper part of the Rivière du Gouffre, flowing in the unorganized territory of Lac-Pikauba, in the Charlevoix Regional County Municipality, in the administrative region of Capitale-Nationale, in the province of Quebec, in Canada. The lower part of this valley does not have roads suitable for cars because of the very mountainous terrain. The upper and middle parts of this valley are served by a few secondary forest roads which connect to the west with route 381. Forestry is the  main economic activity in this valley; recreational tourism, second. The surface of the lower Îlets river is generally frozen from the beginning of December until the beginning of April; however, safe circulation on the ice is generally done from mid-December to the end of March. The upper part of this river has a freezing period of about one more week. The water level of the river varies with the seasons and the precipitation; the spring flood generally occurs in April.
