, 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 38 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. Priest's Bay used to also have a second, smaller island, but wake from waterskiers eroded the island. Now it's simply a shallow section in the bay, with the shallowest points being not even a foot deep. Other parts of the bay are also facing minor shoreline issues due to wake from boaters.

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.
