Using data from fish and habitat surveys throughout the Goose Creek watershed, we found that diversity in cover (e.g., large wood, undercut bank), substrates (e.g., boulders, gravel), water velocity, and water depths were all important in explaining diversity in the fish community across sample sites
The distribution of Northern Leatherside Chub in Goose Creek is influenced by streamflow complexity, and that streamflow complexity is typically higher when active or abandoned beaver dams are present. This suggests beaver reintroductions or beaver dam analogs should be evaluated as a stream restoration practice for Northern Leatherside Chub conservation in an adaptive management framework.
Northern Leatherside Chub also select microhabitats with overhead cover from mature woody and herbaceous riparian vegetation and streamflow complexity influenced by riffle-pool morphology, overhanging bank vegetation, and beaver dams. Maintaining riparian health standards should create Northern Leatherside Chub habitats used at small spatial scales to presumably benefit population dynamics that facilitate persistence
