Course
The river begins at Black Sturgeon Lake, southwest of Lake Nipigon, and flows southeast over the Split Rapids to Nonwatin Lake where the right tributary Nonwatin River and left tributary Ferguson Creek join. It turns south, passes Mount Magee on the left, and continues southeast over the Gardener Rapids and Black Sturgeon Dam, and further downstream heads under Ontario Highway 11 / Ontario Highway 17, the Canadian National Railway line and the Canadian Pacific Railway mainline at the settlement of Everard. The Black Sturgeon turns abruptly southwest and reaches its mouth at Black Bay on Lake Superior, about 6 kilometres (4 mi) southeast of the community of Hurkett.
Geology
The river valley and Black Sturgeon Lake follow a major fault line, the Black Sturgeon Fault, which runs north-south. The valley also contains sills with columnar jointing which are related to the Midcontinent Rift System.
Economy
Black Sturgeon River Provincial Park is a waterway park and occupies the land from Black Sturgeon Dam north to and including the lands around Black Sturgeon Lake.
