Fishes of the Harney Basin revisited: A contemporary assessment of the distribution of fish fauna throughout the Harney Basin from 1990 to 2019 (ver. 2.0, April 2022)

We compiled electrofishing and habitat data sampled from 1990 to 2019 in the Harney Basin by the US Geological Survey (USGS), Oregon Department of Fish and Wildlife (ODFW) and the High Desert Partnership (HDP) to describe native and non-native fish distributions and their habitat associations. USGS and HDP collected eDNA data in 2018 and 2019 to refine the known distributions of common carp (Cyprinus carpio), redband rainbow trout (Oncorhynchus mykiss), largemouth bass (Micropterus salmoides), and smallmouth bass (Micropterus dolomieu). Site transect length, channel width, depth, and gradient were recorded concurrently with fish sampling. Site elevation was derived from statewide digital elevation models (DEM). We used Tableau, a visualization platform, to display fish distributions in the Harney Basin. This interactive tool can be found at https://doi.org/10.5066/P9MUUIY8.
