Lake Troïlus is of the Broadback River watershed, located in Baie-James, in the Nord-du-Québec, in the province of Quebec, Canada.
This body of water is part of the Assinica Wildlife Sanctuary. The surrounding areas are conducive to hunting and fishing.
The hydrographic slope of the Troilus is generally difficult to access, except for some forest roads for forestry and recreational tourism activities. These roads connect on the west side to a main road leading south to Chibougamau; this route passes west of Troilus Lake, straddling the strait between the main part of Troilus Lake and Moleon Bay (located to the southwest).
The surface of Troilus Lake is usually frozen from late October to early May, however safe ice movement is generally from mid-November to the end of April.
