Launching access for boats and canoes on the Lower Au Sable.
Whirlpool provides launching access for small fishing boats and canoes on the Lower Au Sable. For those travelers that don't want to negotiate steep banks or don't have a boat to get out onto the water an accessible boardwalk leads to a hardened fishing access area. This portion of the Au Sable lies below the last dam and looks very much like a natural river making it a choice stretch to canoe. Salmon and steelhead trout fishing is very popular during the spring and fall spawning migration. Signs tell the story of the lake sturgeon, a protected species in Michigan.
