The rivière la Retenue (English: Retained River) is a tributary of the east bank of the Ferrée river. It flows in the municipalities of Château-Richer and L'Ange-Gardien, in the La Côte-de-Beaupré Regional County Municipality, in the administrative region of Capitale-Nationale, in the province of Quebec, in Canada.
The lower part of this valley is served by roads around Lac la Retenue. The intermediate part which follows the foot of the big mountain, is served by a forest road for the needs of forestry and the maintenance of high-voltage lines of Hydro-Quebec. The upper part, which is difficult to access because of the mountainous terrain, is served by a forest road from the north. Forestry is the main economic activity in this valley; second, recreational tourism.
The surface of the Retained River is generally frozen from the beginning of December until the end of March; however, safe traffic on the ice is generally from mid-December to mid-March. The upper part of the river is subject to a frost period of about a week more due to the altitude. The water level of the river varies with the seasons and the precipitation; the spring flood occurs in March or April.
