Gosselin Lake (length: 8.3 kilometres (5.2 mi); elevation: 414 metres (1,358 ft)) is the head lake of the Gosselin River. This lake is located at 49.0 kilometres (30.4 mi)
west of the village of Parent at 27.0 kilometres (16.8 mi) southeast of the village of Clova, Quebec through the Canadian National Railway. Gosselin Lake extends to the southwest, almost parallel (on the north-west side) to the Fortier River (Panache River tributary).
From the mouth of Gosselin Lake, the headwaters of the Gosselin River flow southwest and then south, crossing a few lakes. The total length of the Gosselin River is 5.4 kilometres (3.4 mi).
