Bamaji Lake

Bamaji Lake is a lake in the Albany River and James Bay drainage basins in Kenora District, Ontario, Canada located about 120 km north of Sioux Lookout. It is about 30 km long and 5 km wide at its widest, but typically only 1 km wide.

The primary inflow, from North Bamaji Lake, and outflow, to Roadhouse Lake, is the Cat River, which flows into Lake St. Joseph and then via the Albany River to James Bay. Secondary inflows are Bamaji Creek, the Brokenmouth River, and an outlet channel from Fry Lake.

The Slate Falls First Nation and associated Slate Falls Airport are just to the north on North Bamaji Lake.
