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 <\/span>September 24, 2026 and includes<\/strong> <\/span>ALL SPECIES <\/strong>documented in a single feature class depicting <\/span>fish distribution streams<\/u>. A separate, companion feature class documents regional <\/span>fish distribution lakes<\/u>. The hydrography used to construct this feature class primarily originates from and is coincident with the High Resolution National Hydrography Dataset (NHD-HR) where compatible with state partner agency's internal systems. Distribution is based upon survey data and, in some cases, the best professional judgement by local fish biologists, in the Pacific Northwest Region (Oregon, Washington, Idaho, Montana, and California). Historical distribution records may be based on past observations, literature reviews, or anecdotal data as reviewed by agency biologists. 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 confirmed standardization and 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 <\/span>StreamNet<\/span><\/a> and <\/span>CalFish<\/span><\/a> websites and are also publicly available on ArcGIS Online and via public web mapping applications. <\/span><\/p>

NOTE:<\/u> Individual species layers included here may not be comprehensive in coverage but, rather, represent best available data as of the publication date. The individual species layers are all based on filters from the same primary source layer \u2018Fish Distribution - All Species Combined\u2019, which includes a total of 122 species. Filter that layer by [Species] or [Species_Run] to explore the full range of available data or create custom view layers to meet your needs based on this resource. <\/span><\/p><\/div><\/div><\/div>", "licenseInfo": "

Data are collected at various scales by StreamNet's partners. This dataset represents believed instances of fish distribution or habitat that likely currently supports <\/span>or historically supported <\/span>fish distribution. As every stream has not been fully evaluated, this is not an all-inclusive list of fish distribution in this region. Each linear feature included in this feature class represents a stream segment of suitable habitat currently or historically believed to be utilized by wild, natural, and/or hatchery fish populations and/or streams where sightings of wild, natural, and/or hatchery fish have been documented. Please carefully note values in the [UseType] field to clearly identify streams that are being identified as <\/span>'Historical' <\/span>use areas for some species. This inclusion is intentional though not yet compiled for all species region-wide. Please read the metadata thoroughly and contact PSMFC's GIS team (gis@psmfc.org) with specific questions - especially if using this dataset in any official assessment efforts. <\/span><\/p><\/div><\/div><\/div>", "catalogPath": "", "title": "Fish Distribution (StreamNet & CalFish)", "type": "Map Service", "url": "", "tags": [ "Fish Distribution Streams", "Washington", "Oregon", "Idaho", "Montana", "California", "Columbia River Basin", "Pacific Northwest", "SteamNet", "CalFish" ], "culture": "en-US", "portalUrl": "", "name": "Fish_Distribution", "guid": "E959B492-3C30-47AA-B97E-10B7D67E803B", "minScale": 0, "spatialReference": "WGS_1984_Web_Mercator_Auxiliary_Sphere" }
