The Lower South Branch of the Thunder Bay River flows through Alpena County in northeast Michigan, part of the larger Thunder Bay River watershed that drains into Lake Huron's Thunder Bay. This stretch offers a quieter, more intimate paddling and fishing experience compared to the main river — expect a narrower channel with wooded banks and decent current. The single launch point here serves as access for canoe and kayak trips as well as small-boat fishing.
The Thunder Bay River system is well known for its seasonal steelhead and salmon runs, and the South Branch contributes cold-water flow that supports trout habitat in its upper reaches. Smallmouth bass and northern pike are common in the slower, deeper pools. Camper's Cove RV Park & Canoe Livery sits nearby, suggesting this stretch sees regular paddling traffic. The Thunder Bay River State Forest provides additional public land access along the corridor, and the city of Alpena is just downstream where the river meets Thunder Bay.
