On October 30, 2008 the river was designated a State Scenic River by the Director of the Ohio Department of Natural Resources.
In 1985 the first two miles of the river was named an Area of Concern by the International Joint Commission, primarily because of Fields Brook, a tributary that had received discharges from 19 industries between the 1940s and 1970s. The cleanup was deemed complete in 2014.
