In 2024, the National Park Service (NPS) completed a federal lands update of the Nationwide Rivers Inventory (NRI) using readily available planning information from regional NPS staff and the three other wild and scenic river-administering agencies—the Bureau of Land Management, the U.S. Fish and Wildlife Service, and the U.S. Forest Service. The update removed 320 miles of rivers that have been designated as wild and scenic rivers, updated atribute information for existing NRI river segments, corrected existing geospatial data to reflect river shape and mileage more accurately, and added approximately 1,300 segments (nearly 10,000 miles) to the NRI. This update brought the total number of segments to just under 4,500, and the total mileage in the NRI to approximately 90,000 miles.
This update also includes a new interactive map where users can Explore the Nationwide Rivers Inventory. This map allows for searching by location, managing agency, park, and more! Users can also download river data, add layers to the map, and find the outstandingly remarkable free-flowing rivers closest to home.
