Lac Grand (Quebec)

Lac Grand is a lake in the Outaouais region of Quebec, Canada. It covers an area of about 377 hectares and lies at an elevation of 160 m above sea level. There are no settlements on the lake, although it has many cottages on its shore. Despite having many cottages, some permanent residents live on the lake. Watersports such as waterskiing and sailing are popular among residents of the lake. Other popular recreation includes fishing and swimming.

The lake community recently published a book for lake residents entitled "The Grand Experience", covering the history and geography of the lake.

Geography
The lake consists of four main bays, two in the south, two in the north. The main section of the lake is where it reaches its deepest depths, going as deep as 40 metres below the surface, which is slightly deeper than significantly larger Lake Winnipeg. There are many islands in Lac Grand, the largest being Ile-Des-Peres in Priest's Bay.

Lac Grand has two inflows, including a stream and waterfall from Lac McArthur and a narrow section of water from Lac Vert. Lac Grand's only outflow is into Lac Dam (sometimes spelled Lac Dame), which flows into Lac Brassard and finally Lac McGregor.

There are several minerals to be found in the area, the most prominent being mica, both blue and black in colour, but green, caramel and black serpentine as well as olivine can be found as well.

History
The lake used to be the location of a mica mine.
