The lake serves as a reservoir for the hydro-electric generating station at Deer lake, which was constructed to provide power for the Pulp and Paper Mill at Corner Brook. Contained with the lake is the 18th largest lake-island in the world, Glover Island.
It is located on the west side of the Island, 24 km southeast of the city of Corner Brook. Fed by numerous small streams and brooks, it drains into Deer Lake via the 11-km Humber Canal, and then via the Humber River (Newfoundland), into the Bay of Islands. The lake contains the uninhabited Glover Island (178 km2). Together with its feeder lakes, Sandy and Birchy, Grand Lake forms a waterway much used by recreational boaters.
