Description: This dataset documents fish distribution and habitat use types from data submitted to the regional StreamNet and CalFish projects by partner agencies. This dataset was compiled from separate spatial datasets contributed by partners as of March 12, 2026 and includes for ALL SPECIES documented in a single feature class depicting fish distribution streams. A separate, companion feature class documents regional fish distribution lakes. The hydrography used to construct this feature class primarily originates from and is coincident with the High Resolution National Hydrography Dataset (NHD-HR). Distribution is based upon survey data and, in some cases, the best professional judgement of local fish biologists, in the Pacific Northwest Region (Oregon, Washington, Idaho, Montana, and California). These data were collected by biologists at the state fish & wildlife agencies of Washington (WDFW), Oregon (ODFW), Idaho (IDFG), Montana (MFWP), and California (CDFW). These separate partner agency source layers (identified in the References section of this metadata record) were submitted to the GIS staff at Pacific States Marine Fisheries Commission (PSMFC) where PSMFC GIS Center staff conducted combined source data in to a single consistent regional dataset that meets the regionally agreed upon fish distribution data standard (for streams and lakes). These and other related data are available for download from the StreamNet and CalFish website and are also publicly available on ArcGIS Online and via public web mapping applications.
