What are the obligations of the river-administering agency with regard to water quality?

The river-administering agency is obligated to identify, monitor and report violations of water quality standards to the appropriate federal or state agency. In addition, the river-administering agency often develops and implements management actions to protect and enhance water quality through partnerships with local and state agencies, and water conservation districts. The Wild & Scenic Rivers Act, however, does not reassign EPA and/or state responsibility for implementation of the Clean Water Act to the river-administering agency.
