Class II Shell Rock River, IA/MN

The Shell Rock River has its source at Albert Lea Lake in Albert Lea, Minnesota. It ends where it joins the West Fork of the Cedar River about five miles above Cedar Falls. Its entire length is navigable by canoe, with a little wading now and then to pass shallow riffles if the water is low. The bottom varies from sand to limestone rubble and for miles on end the banks are open park-like meadows. (Iowa DNR)
