Abstract
Etowah River shoals were surveyed to identify sediment sources, prioritize restoration sites, and investigate the relationships among stream geomorphology, in-stream habitat, and aquatic fauna. An essential and unique part of the survey was to integrate traditional geomorphic data collection with ecological information in order to build an understanding of which restoration techniques and sites would have the maximum ecological benefit to federally listed, rare, and endemic shoal-inhabiting species. The following analysis examines 1) whether entrenchment ratio, a commonly used indicator of geomorphic degradation, can be used to predict in-stream shoal habitat and restoration site selection and 2) whether paired comparisons of shoals up- and downstream from tributaries are useful in assessing sediment input. Our preliminary findings indicate that no relationship between entrenchment and five in-stream shoal habitat variables exist. Additionally, upstream- downstream comparisons of shoals show no overall trend.
