Rohault Lake is a freshwater body of the unorganized territory of Lac-Ashuapmushuan, Quebec, in the western part of Le Domaine-du-Roy, in the administrative region of Saguenay-Lac-Saint-Jean, in province of Quebec, in Canada. This lake extends into the townships of Rohault, Robert and Ducharme (near the mouth).
Forestry is the main economic activity of the sector. Recreational tourism activities come second.
The western part of the Lake Rohault hydrographic slope is accessible via the R1032 forest road (North-South direction). The forest road route 167 passes north-east of Nicabau Lake, connecting Chibougamau to Saint-Félicien, Québec. The Canadian National Railway runs along this road. The northern part of lake Rohault is served by the forest road serving the Nemenjiche River.
The surface of lake Rohault is usually frozen from early November to mid-May, however, safe ice circulation is generally from mid-November to mid-April.
Geography
Lake Rohault has a peninsula attached to the north shore and extending over 8.3 kilometres (5.2 mi) towards the center of the lake. This lake has about a hundred islands, the largest of which lies on the North 5.9 kilometres (3.7 mi) side along the west shore of the lake. A strip of land stretching northward on 11.3 kilometres (7.0 mi) distinguishes Lake Rohault and Lake Bouteroue (located on the east side). On the east side, Gaudreau Bay extends northward for 11.6 kilometres (7.2 mi). The current flows through this bay to the mouth of the lake at the bottom of another bay on the east side.
The mouth of Lake Rohault is located at:
- 8.5 kilometres (5.3 mi) north-west of the mouth of the Bouteroue Lake;
- 10.2 kilometres (6.3 mi) northwest of the mouth of Bouteroue Creek (confluence with the Normandin River);
- 19.7 kilometres (12.2 mi) northwest of the mouth of Poutrincourt Lake;
- 38.1 kilometres (23.7 mi) northwest of the mouth of Ashuapmushuan Lake;
- 160.6 kilometres (99.8 mi) south-west of the mouth of the Ashuapmushuan River (confluence with lac Saint-Jean.
