The Nationwide Rivers Inventory (NRI) is a listing of more than 3,200 free-flowing river segments in the United States that are believed to possess one or more "outstandingly remarkable" natural or cultural values judged to be at least regionally significant. Hence, NRI river segments are potential candidates for inclusion in the National Wild and Scenic River System.
Under the Wild and Scenic Rivers Act section 5(d)(1) and related guidance, all federal agencies must seek to avoid or mitigate actions that would adversely affect NRI river segments. The NPS provides instructions on the process of consulting on projects potentially affecting NRI segments.
If you have questions regarding a specific project or need consultation on a Nationwide Rivers Inventory segment, please contact the appropriate regional coordinator on our contact us page.
