This coverage is a spatial representation of most of the Pacific Northwest hatchery facilities in the StreamNet database. Information about the location of each hatchery was collected from StreamNet personnel at WDFW (Washington Dept of Fish & Wildlife), ODFW (Oregon Dept of Fish & Wildlife), IDFG (Idaho Dept of Fish & Game), and MFWP (Montana Fish, Wildlife & Parks) and the tabular information about each hatchery in the StreamNet database was then added to each hatchery point in the GIS coverage.

These data were compiled by the StreamNet partnership and were last updated on January 31, 2019. Distribution represents current presence and habitat use by species and run timing (for anadromous fish) and is based on a combination of field data and the best professional judgement of local fish biologists, in the Pacific Northwest Region (Oregon, Washington, Idaho and Montana). These data were collected by biologists at the state fish & wildlife agencies of Washington (WDFW), Oregon (ODFW), Idaho (IDFG) and Montana (MFWP). Data were then compiled by StreamNet staff into spatial datasets at the agency level. These data were then submitted to the StreamNet regional staff at Pacific States Marine Fisheries Commision (PSMFC) where the regionally consistent distribution feature class is maintained and published. These and related spatial datasets are available for download along with metadata from http://www.streamnet.org/data/interactive-maps-and-gis-data/Note: The referenced web map service includes multiple map layers. In addition to this top level item, some of the individual map feature layers are available and described as separate items within the StreamNet group on ArcGIS Online.

This dataset is a record of fish distribution and activity for WHITE STURGEON contained in the StreamNet database. This feature class was created based on linear event data extracted from the StreamNet database on January 12, 2012. Distribution is based upon the best professional judgement of local fish biologists, in the Pacific Northwest Region (Oregon, Washington, Idaho and Montana). These data were collected by biologists at the state fish & wildlife agencies of Washington (WDFW), Oregon (ODFW), Idaho (IDFG) and Montana (MFWP).

The CalFish Abundance Database contains a comprehensive collection of anadromous fisheries abundance information. The "Other Fish" category contains data collected for species other than salmonids, or salmonids that have not been identified as to species. Beginning in 1998, the Pacific States Marine Fisheries Commission, the California Department of Fish and Game, and the National Marine Fisheries Service, began a cooperative project aimed at collecting, archiving, and entering into standardized electronic formats, the wealth of information generated by fisheries resource management agencies and tribes throughout California. Extensive data are currently available for chinook, coho, steelhead and to a lesser degree other fish species as well. Major data categories include adult abundance population estimates, actual fish and/or carcass counts, counts of fish collected at dams, weirs, or traps, and redd counts. Updates are made to the CalFish web server quarterly. This CalFish Abundance Database shapefile was generated from fully routed 1:100,000 hydrography. In a few cases streams had to be added to the hydrography dataset in order to provide a means to create shapefiles to represent abundance data associated with them. Streams added were digitized at no more than 1:24,000 scale based on stream line images portrayed in 1:24,000 Digital Raster Graphics (DRG). These features generally represent abundance counts resulting from stream surveys. The linear features in this layer typically represent the location for which abundance data records apply. This would be the reach or length of stream surveyed, or the stream sections for which a given population estimate applies. In some cases the actual stream section surveyed was not specified and linear features represent the entire stream. In many cases there are multiple datasets associated with the same length of stream, and so, linear features overlap. Please view the associated datasets for detail regarding specific features. In CalFish these are accessed through the "link" that is visible when performing an identify or query operation. A URL string is provided with each feature in the downloadable data which can also be used to access the underlying datasets. The data that is available via the CalFish website is actually linked directly to the StreamNet website where the database's tabular data is currently stored.

The Watershed Boundary Dataset (WBD) is a comprehensive aggregated collection of hydrologic unit data consistent with the national criteria for delineation and resolution. It defines the areal extent of surface water drainage to a point except in coastal or lake front areas where there could be multiple outlets as stated by the "Federal Standards and Procedures for the National Watershed Boundary Dataset (WBD)" “Standard” (http://pubs.usgs.gov/tm/11/a3/). Watershed boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. This dataset represents the hydrologic unit boundaries to the 12-digit (6th level) for the entire United States. Some areas may also include additional subdivisions representing the 14- and 16-digit hydrologic unit (HU). At a minimum, the HUs are delineated at 1:24,000-scale in the conterminous United States, 1:25,000-scale in Hawaii, Pacific basin and the Caribbean, and 1:63,360-scale in Alaska, meeting the National Map Accuracy Standards (NMAS). Higher resolution boundaries are being developed where partners and data exist and will be incorporated back into the WBD. WBD data are delivered as a dataset of polygons and corresponding lines that define the boundary of the polygon. WBD polygon attributes include hydrologic unit codes (HUC), size (in the form of acres and square kilometers), name, downstream hydrologic unit code, type of watershed, non-contributing areas, and flow modifications. The HUC describes where the unit is in the country and the level of the unit. WBD line attributes contain the highest level of hydrologic unit for each boundary, line source information and flow modifications.
