Description: The Nationwide Rivers Inventory (NRI) is a listing of free-flowing river segments in the United States and Puerto Rico 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), a 1979 Presidential Memorandum, and 1980 Council on Environmental Quality (CEQ) guidance, all federal agencies must seek to avoid or mitigate adverse impacts to NRI rivers. Associated Department of the Interior and National Park Service policy and guidance provides direction on Nationwide Rivers Inventory responsibilities.The NRI is a source of information for statewide river assessments and federal agencies involved with stream-related projects. Always coordinate with local land managers to see if there are other river resources that may need to be considered. For any group concerned with ecosystem management, the inventory can provide the location of the nearest naturally- functioning system which might serve as a reference for monitoring activities. For the recreationalist, it provides a listing of free-flowing, relatively undisturbed river segments. An interactive map for users to search and filter for river segments listed in the NRI is available at nps.gov/nri.The National Park Service (NPS) maintains the Nationwide Rivers Inventory, which was originally compiled in 1982 in partial fulfillment of the Wild and Scenic Rivers Act (Section 5). Between 1982 and 1988, there were at least two groups of additions made to the original NRI using these procedures. Although data on the number of segments added in the first revision cannot be located (other than the Manumuskin River, NJ), the second revision added the Chester (MD), Merrimack (NH), and Connecticut (CT) rivers to the NRI with Director Mott's signature on January 26, 1988. Three years later, the NRI was republished and distributed with the additional revisions.In 1990, NPS officials at the national and regional levels began to discuss an official update of the NRI. NPS national river policy staff created goals and objectives for the NRI update and decided the update should take place in two phases: 1) identification of segments on Federal lands found eligible for wild and scenic river designation through agency studies, and 2) identification of segments which the states believed contained ORVs.In 1993, a federal lands update was initiated as part of the celebration of the 25th anniversary of the National Wild and Scenic Rivers Act. The update added new information on existing listings and added new river segments found on lands managed by the Bureau of Land Management, National Park Service, and U.S. Forest Service. NPS hired six interns over the course of a year to compile segment information from natural resource agency management plans. With NPS Director Roger Kennedy's signature, 1,012 segments equaling 12,713 river miles were added, and 464 river segments were updated.In 2016, the NPS made technical corrections to the NRI based on more recent studies and readily available information and modified river segments to remove designated Wild and Scenic River reaches, resulting in 3,213 river segments (down from 3,439 in the original access files and 2,805 in the original GIS shape file). River segments in the geospatial data were updated with high-resolution (1:24,000) National Hydrography Dataset (NHD) and attribute information was added.In 2024, the NPS updated the NRI for the first time in over 30 years. Additions and technical corrections were incorporated from the four wild and scenic rivers administering federal agencies (National Park Service, U.S. Forest Service, Bureau of Land Management, and U.S. Fish and Wildlife Service) to add over 12,000 miles of rivers, tributaries, and creeks across approximately 1,300 new river segments. This data was based on readily available planning information from the agencies listed above.
