The Miami Bar to Oak Flat section of the Illinois River in Oregon is a beautiful river run, best floated in the late spring or early summer. The water can be fast and challenging during high water periods, with some Class III rapids and small drops to navigate. At lower water levels, the river becomes more technical, with tight channels and rocks to avoid. There are several obstacles along the way, including a large boulder garden just upstream of Oak Flat, which requires careful maneuvering. Recommended CFS for this stretch of river is between 800-1500. Overall, this is a fun and challenging river run suitable for intermediate paddlers.
