This publication contains data from a two-phase 1998-1999 study in the Frank Church Wilderness which surveyed visitors about the use of motorboats and jet boats on the Salmon River. This study was done in coordination with the Western Whitewater Association (WWA) and Northwest River Runners (NRR), which are jet boat organizations based in Boise and Lewiston, ID, respectively. Information was gathered regarding visitor demographics and opinions on river use. Phase I included interviews with six leadership members of the WWA. Included in this data publication are notes from two of those interviews and excerpts from all six interviews. Phase II included sending surveys to jet boat users. Data include the results of these mailback surveys. Follow-up telephone surveys were conducted if the mailback surveys were not returned and those results have also been included.
