The Eastern side of the Nemenjiche River hydrographic slope is accessible by a forest road (North-South direction) that separates from route 113 which links Lebel-sur-Quévillon to Chibougamau.

The West side is served by the R1032 road that goes North to the South of Lake Fancamp.

The surface of the Nemenjiche River is usually frozen from early November to mid-May, however, safe ice circulation is generally from mid-November to mid-April.

This lake is located at 0.7 kilometres (0.43 mi) on the west side of the demarcation line between the Regional County Municipality (RCM) of Le Domaine-du-Roy and the Eeyou Istchee Baie-James; this demarcation constitutes the watershed between the James Bay side and the Lac Saint-Jean slope.

Of elongated shape in the North-South direction, this lake comprises about forty islands.
