It originates in a swamp south of Belknap and east of Hawks.

The river enters the small Swan Lake, just southeast of Calcite limestone quarry, before reaching its mouth in Lake Huron, in a small bay between Adams Points and Quarry Point.

The river is not navigable but provides a salmon habitat.

It is annually stocked with hundreds of thousands of chinook salmon and in the 1980s was also stocked with coho salmon and lake trout.
