Each feature class or feature dataset is in Geographic (GCS) NAD83 unless otherwise noted
This dataset contains a record of fish distribution and life history stage of summer steelhead salmon, based upon the best professional judgement of local fish biologists, as of year 2003 within the geographic area depicted by the John Day Basin third field hydrologic unit boundary (HUC). These data were collected by biologists at the state fish & wildlife agency of Oregon (Oregon Department of Fish and Wildlife). Data were then compiled by StreamNet staff into paper maps or event tables at the state level. These event tables were submitted to the StreamNet regional staff at Pacific States Marine Fisheries Commision (PSMFC) where this regional distribution coverage was created from these event tables. All data are referenced to the PNW 1:100,000 River Reach Hydrography () on the LLID-based stream routing system.
The intended use of this dataset was to map fish distribution and activity for analysis in the John Day Resource Management Plan.
