Black Sturgeon River (Thunder Bay District)

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.[1] In 1959, a dam was constructed on the Black Sturgeon river. Originally, this was done in order to control water levels, yet it also ended up preventing access to the upper reaches of the river. Many speculated that this construction is what led to the collapse of the most common fish type in the area, the walleye.[2]

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.

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.[1]
