[1][2] The lake is on the Kabinakagami River and is part of the James Bay drainage basin.

Rocky Point lies between it and the large bay that forms the north end of the lake, where the Kabinakagami River leaves over the Big Rapids.

In the late 18th-century, the North West Company (NWC) had a trading outpost on the lake.

The Hudson's Bay Company (HBC) also set up a post in 1796, called Cappoonicagomie, but abandoned it around 1806.

[3] The HBC post (called variously over time as Capoonacaugamy, Capenocoggamy, Caponicaugummy, Capoonicaugummie, Kabinakagimi, and Kabinokagami) functioned as an outpost of New Brunswick House for its entire existence.
