How does wild and scenic river designation affect livestock grazing practices on federal lands inside the corridor?

Generally, existing livestock grazing practices and related structures are not affected by designation. The Interagency Guidelines state that agricultural practices should be similar in nature and intensity to those present in the area at the time of designation, and that grazing may be compatible with all river classifications (wild, scenic or recreational). Grazing and other public uses may occur in a wild and scenic river corridor as long as the uses do not adversely impact or otherwise degrade the values for which a river was designated.
