The area of "Lac des Vents" extends in the townships of Lescure, Druillettes, Rasles and Hazeur, on the territory of the Eeyou Istchee James Bay (municipality) regional government, south of Chapais, Quebec.

Recreational tourism activities come second, notably thanks to various navigable water bodies located in the area.

Formed by an enlargement of the Opawica River, the "Lac des vents" is rather deformed, comprising an archipelago of islands in the North-West, numerous bays and peninsulas.

The Opawica River crosses the northern part of this lake on 14.7 metres (48 ft) bypassing this peninsula by the south.

Another peninsula attached to the east bank, south of the Opawica River confluence, stretches 5.7 kilometres (3.5 mi) to the southwest of the lake, parallel to the current.
