Lac La Martre sits in the western part of the Northwest Territories in a broad boreal-wetland landscape. The area is remote from large centres and is accessed from regional settlements and airstrips.

  • Wildlife importance: Ranked among the larger lakes in the Northwest Territories, it is noted for its importance to migratory waterfowl and other wetland wildlife.
