  Description:
    Abstract:
      These data set represents a delineation and description of individual populations of Columbia River Basin salmon populations at the 6th field hydrologic unit scale. Populations include fall Chinook, spring/summer Chinook, Coho, Chum, Sockeye salmon, and winter steelhead, summer steelhead, and Kokanee trout. Populations are generally aggregations of spawning fish that are genetically distinct from other populations within their species/run and contain their own distinct characteristics. Because genetics are not readily available in many cases, these populations may also be identified and separated based on their life history patterns or other considerations. This information was primarily generated by reviewing all of the Columbia subbasin plans created in the recent (2000-2005) Northwest Power and Conservation Council planning process, a review by Columbia Basin Fish & Wildlife (CBFWA) biologists and managers, and for populations already listed under the Endangered Species Act, by matching these populations as closely as possible to the NOAA TRT Fish Population database. Populations were delineated and described according to the information from these data sources, although in some cases other information was also used to augment or confirm these descriptions.

      Each fish population table relates using a HUC6 attribute to a polygon GIS file of 6th field hydrologic units (subwatersheds) of Washington, Oregon, and Idaho. Any given population will usually be related to multiple subwatersheds. Populations were generally allocated to spawning areas, although in some cases, migratory corridors and rearing areas are also included for a logical separation of population boundaries. Several attributes (fields) pertain to each unique population, including information about its current status, timing of spawning, genetic fitness, age/sex composition, and in-watershed harvest. In some cases these attributes are incomplete because the data were not available. Additional quantitative information about a population such as its abundance, spawning capacity, and production may be obtained from an Ecosystems Diagnosis & Treatment (EDT) fish populations table if a population was modeled with EDT during Subbasin Planning and/or from an ancillary spreadsheet of fish population statistics compiled by Ron Costello (NOAA) (See data sources under supplemental information).

      Several management attributes (including the management designation of each population under the NOAA Evolutionarily Significant Units (ESUs), the US v Oregon case, and the Pacific Salmon Commission are also contained in this data set. These attributes are generally unique for each population, but in some cases, fish populations may split these management boundaries and a population may contain more than one management designation under any of these regimes.

      For some species, additional information was also added, including USvOR treaty take limits and a note on whether the fish population or a geographic component of it has been included in the genetic baseline information being collected by the Hagerman Fish Culture Experiment Station.

      During 2007, fish managers affiliated with the Columbia Basin Fish & Wildlife Authority (CBFWA) reviewed these population definitions, and made suggested revisions. These revsions were subsequently captured in this GIS data set in two attributes: CBFWA_PopName and CBFWA_Comments. All suggested revisions were implemented where detailed there if they suggested changes to other attributes or boundaries of the population. Because this has been the highest level review of the data, we suggest that users refer to the CBFWA_PopName as the "official" population name unless they are interested in the original data as captured, in which case they should refer to the SubPlan_PopName. An additional field (RJC_StockID) was also added, which links this population to its corresponding stock described in the comprehensive fish population information spreadsheet created by Ron Costello (NOAA) during 2007.

      During 2008, the NOAA TRT fish populations database was finalized to show the defnitions of ESA-listed populations. This data set was compared to these definitions and modified to match these definitions as closely as possible within the given data structure. Addtiional information from the NOAA database were added, and further information can be obtained directly from the NOAA database (see link under supplemental information).

      To use the data in a GIS, add both the fish population table of interest from the geodatabase and the CBHUC6 (subwatershed) spatial layer to a map view. Establish a join between the table and the subwatershed spatial layer using the unique HUC6 attribute from each file. Attributes of the fish populations should then be displayable on the subwatershed polygon units. To map individual fish populations, use the CBFWA_PopName attribute. It's also possible to view the data without a GIS, by opening it using Microsoft Access database software.

    Purpose:
      This data set is intended for use in the identification, evaluation, and display of Columbia River salmonid populations. It may be especially helpful for planning purposes that aim to recover impacted salmon and need to evaluate their relative abundance, distribution, and management. This data set is intended to fulfill a gap in currently available data because it includes populations that are both listed and not listed under the Endangered Species Act, and it incorporates management information about these populations.
    Supplemental_Information:
      Three data sets include additional information about these populations and may be linked directly for matching populations using the attributes described below:

      Source_Contribution:
        Data that were used as inputs and generated by the EDT model are used for several attributes, including age/sex composition, fecundity, and the edt abundance, productiviity, and diversity attributes. More information about EDT is available from: EDT data is available directly from the subbasin plans (see previous link) or also from an archival site at StreamNet (<http://www.streamnet.org/subbasin/SubIndexMap.html>)
    Process_Step:
      Process_Description:
        (1) Obtained watershed boundaries (5th/6th field hydrologic units) for Oregon, Washington, and Idaho, reprojected the data to a Lambert Conformal conic projection, and merged these into one regional layer, adjusting boundaries to match along areas of coincident geometry near state boundaries.

        (2) Obtained digital Columbia subbasin plans. Reviewed each plan to determine the boundaries of fish populations within the subbasin. Selected watersheds corresponding to each population and assigned their population name.

        (3) Entered population and biological attribute information about each population from the subbasin plans, and in a few cases, other sources (as detailed under the attribute: data source).

        (4) Entered management attribute information about each population based on information from CRITFC staff and NOAA ESU data.

        (5) Reviewed the information for spatial and attribute errors or inconsistencies.

        6) Obtained revised 6th Field HUC layer from NOAA fisheries. Migrated all populations to these new hydrologic boundaries.

      Attribute_Definition:
        Identifier of the EDT population that corresponds to this population. Because EDT populations may be smaller than the populations recognized in this data set, in many cases there is a "many to one" relationship between the two, and a fish population may contain multiple EDT populations. The registered EDT population database contains a wealth of information about fish abundance, life history, and productivity, which is used in modelling for 2001/2002 Subbasin Planning. This information is contained in a separate databsae (available from <ftp://ftp.streamnet.org/pub/streamnet/SubPlanning/tools/fish_model_tools/edt/fishpop_databases/>), and may be linked to the population here using this EDT_PopID attribute.

      Attribute_Definition_Source: NOAA Fisheries
      Attribute_Domain_Values:
        Enumerated_Domain:
          Enumerated_Domain_Value: Extant
          Enumerated_Domain_Value_Definition:
            Species are present and have near full access. Fish abundance numbers may be lower than the extinction threshold in some cases (esp. chum)
      Attribute_Domain_Values:
        Enumerated_Domain:
          Enumerated_Domain_Value: Blocked within Extant
          Enumerated_Domain_Value_Definition:
            Species are present for part of historic population range but excluded from the rest of their range within the population due to barriers.
      Attribute_Domain_Values:
        Enumerated_Domain:
          Enumerated_Domain_Value: Blocked within Extant; Transported
          Enumerated_Domain_Value_Definition:
            Species are present via truck in part or all of their historic range.
      Attribute_Domain_Values:
        Enumerated_Domain:
          Enumerated_Domain_Value: Extirpated via Barriers
          Enumerated_Domain_Value_Definition:
            Species were historically present but currently absent due to manmade barriers.
        Enumerated_Domain:
          Enumerated_Domain_Value: Artificial; Transported
          Enumerated_Domain_Value_Definition:
            Species present currently, but historically not present due to natural barriers; fish ?transported? into area via truck, fish ladders, etc.
        Enumerated_Domain:
          Enumerated_Domain_Value: Functionally Extirpated
          Enumerated_Domain_Value_Definition:
            Species were historically present. Areas accessible but population currently absent. Extirpated due to impaired habitat, water quality, other factors (Interior Columbia).
    Attribute:
      Attribute_Label: Access_Huc
      Attribute_Definition: Accessibility of the 6th field Hydrologic Unit (HU)
      Attribute_Definition_Source: NOAA Fisheries
      Attribute_Domain_Values:
        Enumerated_Domain:
          Enumerated_Domain_Value: Accessible
          Enumerated_Domain_Value_Definition:
            Streams in HU are currently accessible to fish, and were historically.
        Enumerated_Domain:
          Enumerated_Domain_Value: Artificial
          Enumerated_Domain_Value_Definition:
            Streams in HU are artificially accessible through anthropogenic methods (passed upstream of natural barrier).
        Enumerated_Domain:
          Enumerated_Domain_Value: Naturally Blocked
          Enumerated_Domain_Value_Definition:
            Blocked by natural barriers. Each TRT used slightly different definitions/cutoffs to define natural gradient cutoffs impacting accessibility of the huc/population.
          Enumerated_Domain_Value_Definition_Source:
            IC = 20% slope for 200 m segment (all species) OR documented barrier feature (eg. waterall, cascades); WLC = natural gradient barriers 16% (chinook and coho); 20% (steelhead) OR documented features (eg. waterfalls);
        Enumerated_Domain:
          Enumerated_Domain_Value: Limited Accessibility
          Enumerated_Domain_Value_Definition:
            Less than complete access (mix of other categories) such as a barrier just upstream from the HU outlet.
        Enumerated_Domain:
          Enumerated_Domain_Value: Anthropogenically Blocked
          Enumerated_Domain_Value_Definition: HU blocked by anthropogenic barrier(s).
        Enumerated_Domain:
          Enumerated_Domain_Value: Trap and Haul
          Enumerated_Domain_Value_Definition:
            HU only accessible through manual passage methods; upstream of weir, dam, other obstruction.
    Attribute:
      Attribute_Label: Split_Txt
      Attribute_Definition:
        Comment describing what was split; explaination of split or modification in the NOAA database. Note that in this data set HUC6 is never split because it is the minimum mapping unit, but this info is included here as a reference to condition in the NOAA database.
      Attribute_Definition_Source: NOAA Fisheries
    Attribute:
      Attribute_Label: HUC_Split
      Attribute_Definition:
        Was the 6th field polygon split or modified from source in the NOAA Database (Y or N). Note that in this data set HUC6 is never split because it is the minimum mapping unit, but this info is included here as a reference to condition in the NOAA database.
