Electrofishing, environmental DNA, and habitat data for watercourses in the Goose Lake Basin, Oregon, U.S.A., 2022–2024

We collected electrofishing, environmental DNA (eDNA), and habitat data from 2022 to 2024 in the Oregon portion of the Goose Lake Basin. Data were collected by the U.S. Geological Survey (USGS) and Oregon State University (OSU) to monitor native and non-native fish distributions in the Basin, and to relate observed abundances to specific habitat features. Sampling was conducted in collaboration with Oregon Department of Fish and Wildlife (ODFW) based on previous survey efforts, using a stratified random subset of sites surveyed by ODFW in 2007 and following the same protocols. We added eDNA to evaluate its efficacy as an alternative to traditional fish sampling methods, and all sample processing was carried out by the Levi Lab at OSU. During fish sampling efforts, we collected habitat data including channel width, depth, temperature, dissolved oxygen, conductivity, and substrate. These data are part of a broader, comprehensive monitoring effort in the Basin.
