Item Identification

Title: SalmonChinook_PugetSoundESU_20050902_line
Publication Date: 2005-08-15

Critical habitat includes the stream channels within the designated stream reaches, and includes a lateral extent as defined by the ordinary high-water line (33 CFR 319.11). In areas where ordinary high-water line has not been defined, the lateral extent is defined by the bankfull elevation. Bankfull elevation is the level at which water begins to leave the channel and move into the floodplain and is reached at a discharge which generally has a recurrence interval of 1 to 2 years on the annual flood series. Critical habitat in lake areas is defined by the perimeter of the water body as displayed on standard 1:24,000 scale topographic maps or the elevation of ordinary high water, whichever is greater.See the final rule (70 FR 52630) for descriptions of areas excluded from this critical habitat designation. Military areas ineligible for designation (qualifying Integrated Natural Resource Management Plan) were not clipped out of the data. Excluded military areas (due to national security impacts), Habitat Conservation Plan (HCP) lands, and Indian lands were not clipped out of the data.


These data represent critical habitat designated (September 2, 2005, 70 FR 52630) under the Endangered Species Act for the Puget Sound Chinook salmon ESU.

These river/stream (line) data should be used in conjunction with nearshore (polygon) data in the SalmonChinook_PugetSoundESU_20050902_poly feature class.

Process Steps

Process Step 1

CC ID: 1113234

Data creation process 2003 - 2004.


1) Fish distribution data was obtained from WDFW. WDFW 2004

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 PS Chinook salmon ESU is made up of three run-types: spring, summer, and fall. The run-types were merged into a single ESU data set.

4) 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

5) The PS Chinook 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.

6) 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.

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

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


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.

*Note: FRN point lists were generated off the original coverages, not generated from the polylines in the shapefiles. Shapefiles were generated from coverages to post on website for sharing.

Process Step 2

CC ID: 1113235

ckpug_chf1.shp (NAD_1927_Albers) geographic transformation, unprojected -> CKPUG_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_ckpug_chf1").

Process Date/Time: 2019-07-17 00:00:00

Process Step 3

CC ID: 1113236

The 2019 version CKPUG_ch.shp (GCS_North_American_1983 wkid 4269) was converted into the standardized feature class SalmonChinook_PugetSoundESU_20050902_line (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_ckpug_chf1" that was stored separately from the source data in ckpug_chf1.shp (NAD_1927_Albers).
