The Lac Blanc is located in the northern part of the municipality of Saint-Ubalde, in the MRC of Portneuf Regional County Municipality, in the administrative region of the Capitale-Nationale, in the province of Quebec, in Canada.

The northwest and south of the lake is served by Chemin du Lac-Émeraude. The northern and eastern parts of the lake are served by secondary forest roads.

Recreational and tourist activities (especially vacationing) constitute the main economic activity in the sector; forestry, second. This lake is linked to Portneuf Regional Natural Park via a 5.1 km cycle path connecting Lac Blanc to Sept Îles Lake.

The surface of Lac Blanc is usually frozen from the beginning of December to the end of March, however the safe circulation on the ice is generally made from mid-December to mid-March.


Lac Blanc has a length of 3.9 kilometres (2.4 mi) and an altitude of 143 metres (469 ft). He gets his supplies from:

  • north side: the Rivière des Pins which receives the waters of "Lac des Pins" (altitude of 183 m), located further north. The latter obtains supplies from the outlet of a series of lakes: Gervais, "du Canard", Saint-Laurent, "de la Galette" and "à l'Équerre";
  • northeast side: the outlet of Emeraude Lake (altitude: 176 m) (located near the Lac Richard mountain);
  • southwest side: the outlet of a series of lakes: Rond (174 m), "à Francis" (155 m), Travers (161 m), Perron (189 m), Perreault (185 m)) and the Lac Froid (197 m).

Lac Blanc is renowned for its resort and recreational tourism activities, including camping and nautical activities. The "Montagne du Lac Blanc" (English: White Lake Mountain), whose summit reaches 228 metres (748 ft), is located on the west side of the lake. The mouth of the lake is located at the bottom of the southwest bay of the lake.

Lac Blanc is located southwest of the boundary of the Portneuf Regional Natural Park. Comprising 70 kilometres (43.50 mi), this park includes the Long lakes, Montauban, Carillon, Sept Îles, Lac en Coeur, "À l'Anguille" and some other more secondary bodies of water. This park is popular for recreational and tourist activities: hiking trails, cross-country skiing, boat launching ramp...
