The Lac des Roches (English: lake of rocks) is a freshwater body of the city of Quebec, in the region of the Capitale-Nationale, in the province of Quebec, in Canada.
It is the main reserve of drinking water in the arrondissement of Charlesbourg. Lac des Roches is mainly fed by five forest streams from the surrounding mountains.
The Lake Saint-Charles is served on the east side mainly by the Lac des Roches road and on the south side by the Arthur-Drolet road for the needs of recreational tourism and forestry.[1]
The surface of Lake Saint-Charles is generally frozen from the beginning of December to the end of March; safe circulation on the ice is generally done from the end of December to the beginning of March.
