Fishdist: 1:24,000 (24K) and 1:100,000 (100K) Statewide Salmonid Fish Distribution

Hydrologic Unit Boundaries for Oregon, Washington, and California

Data creation process 2003 - 2004.

1) Fish distribution data was obtained from WDFW. WDFW 2003

2) Preparation of the WDFW data involved analysis and overlay of event data. Event data were exported to Microsoft Access where macros were used to convert the multiple overlapping usetypes into a single continuous fish distribution layer. For more details on this process see the supporting documentation under the section on "Supplemental information".

3) The ESU data were intersected with the REO watersheds (HUC5s). The result was a network of fish distribution that could be grouped by HUC5s. REO 2002

4) The OL sockeye salmon fish distribution was segmented based on LLID and Fifth Field Watershed (HUC5) boundaries. Unique codes (see HUC5_LLID under attribute definitions) were assigned to each segment allowing for analysis of the data at the watershed scale. This unique identifier can be used to link the Critical Habitat data set to the Habitat Areas data set.

5) The watershed data sets did not match up cleanly with the fish distribution data sets. There were numerous instances where the watershed did not cross the stream network at the correct location. These were often small segments that introduced unnecessary complexity to the data set. We searched for these segments and changed the corresponding HUC5 attribute to match the correct watershed.

6) Data were converted to arc coverage then projected, built and cleaned.

7) The attribute tables were built and attribute accuracy was verified.

2005

In the final stages of the rule making process for critical habitat, we received comments and new information about the distribution of the ESU. During the final review of public comments and new information we revised the distribution of the ESU and made changes to the areas that were excluded from critical habitat. For a more detailed review of the changes between the proposed and final rule please refer to the final determination for critical habitat, and supporting documents.

soozt_chf1.shp (NAD_1927_Albers) geographic transformation, unprojected -> SOOZT_ch.shp (GCS_North_American_1983 wkid 4269).

Geometry was not edited, attributes were not edited, metadata was edited because it was blank (stored separately as html file "metadata_soozt_chf1").

The 2019 version SOOZT_ch.shp (GCS_North_American_1983 wkid 4269) was converted into the standardized feature class SalmonSockeye_OzetteLakeESU_20050902 (GCS_WGS_84 wkid 4326) using the National Critical Habitat Geodatabase processing protocol.

During standardization, geometry was not edited. Attributes were edited. Metadata was edited and populated using the final rule and the 2005 html file "metadata_soozt_chf1" that was stored separately from the source data in soozt_chf1.shp (NAD_1927_Albers).
