We’ve done that stretch a few times. Love the Turkey.
We’ve paddled every eastern Iowa river from mouth or entrance to the state to the Mississippi. My favorites: Yellow (mostly for the fishing), North Fork of Maquoketa, Turkey, Volga, and the Maquoketa proper. The beauty about the Maquoketa is that it’s only an hour from Iowa City and maintains a stunner throughout. Also great sand bars and natural areas to check out. The Upper Iowa gets the publicity, but give me the Maquoketa any day.
Oh and Whitewater Canyon. Depends on the flow, but damn. Nothing like it in Iowa.
Least favorites: Iowa, Cedar (has its moments) and the Wapsi. Just too much adjacent Ag land. Very dirty rivers.
Have you floated down Little Paint in YRF?
