The rivière du Sud (in English: South River) is a tributary of the south bank of the North Eaton River whose current flows successively into the Eaton River, the Saint-François River, then the south shore of the St. Lawrence River.
The Rivière du Sud flows through the municipalities of Saint-Mathias-de-Bonneterre and Newport, in the Le Haut-Saint-François Regional County Municipality (MRC), in the administrative region of Estrie, in Quebec, in Canada.
The neighboring hydrographic slopes of the South River are:
- north side: North Eaton River, Ditton Creek West;
- east side: North Eaton River, Poilu Creek, Mining Creek;
- south side: Canada-US border;
- west side: Lyon stream, Eaton River, North Eaton River.
The South River takes its source from a small mountain lake surrounded by marshes. This lake is located in the eastern part of the municipality of Saint-Mathias-de-Bonneterre (almost at the limit of Chartierville). It is 0.8 kilometres (0.50 mi) northwest of the Canada-US border.
From its source, the South River descends on 10.3 kilometres (6.4 mi) towards the south entirely in a forest zone, with a drop of 190 metres (620 ft) according to the following segments:
- 4.3 kilometres (2.7 mi) first east along the border, then north, to route 210;
- 6.0 kilometres (3.7 mi) north-west, to its mouth. Note: A forest road runs along this segment.[1]
The South River empties on the south bank of the North Eaton River at 1.9 kilometres (1.2 mi) upstream of the mouth of Christmas Creek (coming from the northwest).
