Eligible Suitable Rivers
Eligible Suitable Rivers are those rivers/river segments that have been found through various National Park Service study processes to be eligible and sometimes suitable to become designated as Wild and Scenic Rivers. The listing of Eligible Suitable Rivers within National Park Service boundaries continues to grow through these studies of eligibility and suitability.
Nationwide Rivers Inventory
The Nationwide Rivers Inventory (NRI) is a listing, maintained by the National Park Service, of more than 3,200 free flowing rivers segments believed to have outstanding and remarkable values (including scenic, recreational, geologic, fish, wildlife, prehistoric/historic and other values), making them potentially eligible for a Wild and Scenic designation. Federal Agencies evaluate potential eligibility of NRI segments on lands that they manage. Private land rivers have not gone through the potential eligibility study process. There are currently 389 NRI segments within our boundaries. Learn more about Nationwide Inventory Rivers in each state.
