Two of the tributaries, Flint Creek and Barren Fork Creek, are designated Oklahoma Scenic Rivers.

Oklahoma's instream phosphorus limit still is not being achieved.  Phosphorus levels are many times greater at the Oklahoma border with Arkansas and at Tahlequah, Oklahoma than the Oklahoma phosphorus limit of 0.037 mg/l.
