Description: This polyline feature class represents the segments designated as BLM National Landscape Conservation System (NLCS) Wild and Scenic Rivers. The attributes for this feature class serve to store the feature level metadata information for the polylines, as well as document the origin and characteristics of each polyline. Lines will be segmented when any of the attributes change (e.g. when the classification changes) or to capture changes in Outstandingly Remarkable Value (ORV). Every segment must have at least one record in the related table, nlcs_wsr_orv_tbl.
