The authors thank the cooperators, Northern Shenandoah Valley Regional Commission and Central Shenandoah Planning District and localities therein, for support of this scientific work. Virginia Commonwealth University contributed equipment, travel funds, and supplies as well as in-kind services for this cooperative investigation to develop the fish habitat-suitability criteria. The continued interest and feedback received from policymakers, planners, utility managers, State agency staff, and private citizens enhanced the study process. Appreciation is extended to local landowners for allowing access to the river from their properties. John Gibson of the Downriver Canoe Company allowed access to the campgrounds that accommodated the field staff. Vital field assistance was provided by our lead technician for the project, Dennis Adams (USGS, Marion, Virginia) as well as volunteers from nonprofit organizations, State agencies, universities, and private citizens. Thanks to field volunteers:
