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

Generally, existing agricultural and grazing practices, and related structures are not affected by designation. The Wild & Scenic Rivers Act does not give federal agencies authority to regulate private land. Consequently, the only effect of designation is to authorize the purchase of easements within the river corridor, and to enable federal agency staff to provide technical assistance to private landowners interested in reducing impacts on the river’s water quality and riparian integrity.
