View of the Delaware River at Narrowsburg, NY. National Park Service. Section 7(a) provides the Upper Delaware with permanent protection from federally licensed or assisted dams, diversions, channelization or other water resources projects that would have a direct and adverse effect on its free-flowing condition, water quality, or 'outstandingly remarkable values'; or, for projects upstream, downstream, or on a tributary to the designated segments, that would invade or unreasonably diminish the segment's fish, wildlife, scenic, or recreational resources. The determination of a proposed federally assisted water resources project's potential impacts on a river's outstandingly remarkable values, water quality, and free-flowing condition is made by the National Park Service. Director's Order #46 describes the management responsibilities for designated wild and scenic rivers that are part of the national park system. Congress passed the WSRA to protect selected rivers from dams, diversions, channelization and other projects that have had detrimental effects on so many of the Nation's waterways. Section 7 of the WSRA imposes restrictions on water resources projects in order to protect and enhance the values for which rivers are added to the NWSRS.
