The purpose of the suitability phase of the study process is to determine whether eligible rivers would be appropriate additions to the national system by considering tradeoffs between corridor development and river protection. This report describes the methodology, data considered, and determinations made during the suitability phase. The Wild and Scenic Rivers (WSRs) report is divided into two sections, to accommodate the differences in the Bureau of Land Management (BLM) and Forest Service suitability assessment processes, and to facilitate future agency use of the report.
