The rivière du Barrage (in English: river of the Dam) is a tributary of the east bank of the Samson River, which flows on the east bank of the Chaudière River; the latter flows northward to empty onto the south shore of the St. Lawrence River.
The toponym Rivière du Barrage was formalized on December 5, 1968, at the Commission de toponymie du Québec.[1]
