Sableuse River

The Sableuse River is a watercourse in the Matapedia Valley, in administrative region of Bas-Saint-Laurent, in Quebec, Canada. Its origin lies in the Sableuse ponds in Saint-Vianney while its mouth lies in the Sableuse River Bay on Lake Matapedia.

This river flows into the regional county municipalities (RCM):
 * La Matapedia Regional County Municipality: municipality Saint-Vianney, Quebec and the unorganized territory of Lac-Matapedia, Quebec;
 * La Matanie Regional County Municipality: municipality Sainte-Paule.

This course river of the Matapedia Valley is descending towards the Southwest; it passes through the territory of Sainte-Paule and Matapedia Lake (at the Eastern boundary of the territory of Sayabec).

The Sableuse River flows into the bay of Sableuse River, located on the North shore of Matapedia Lake which discharge empties on the Eastern side in the Matapedia River. The latter flows Southeast into the Matapedia Valley up to the Restigouche River which flows East up to the west bank of the Chaleur Bay. The latter opens to the East on the Gulf of Saint Lawrence.
