Many speculated that this construction is what led to the collapse of the most common fish type in the area, the walleye.

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.

This site also includes other provincial parks, conservation reserves, and management areas around Lake Nipigon, all sharing common geographic themes, recreation uses, and resource issues.

The forests within the park are mostly boreal mixedwood that are generally more species-rich than areas to the east and west.
