What is an Outstandingly Remarkable Value (ORV)?

 To be eligible for designation, a river must be free-flowing and possess one or more outstandingly remarkable values (ORVs).  To be an ORV the resource must be of local, state, regional or national significance.  It must also be river-related such as:  within about 1/4 mile from the riverbank, contribute substantially to the functioning of the river ecosystem, and/or owe its location or existence to the river.
