Item Identification

Title: Coho Salmon (Lower Columbia River ESU)
Publication Date: 2016-06-06

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 (81 FR 9252) for descriptions of areas excluded from this critical habitat designation. Excluded Habitat Conservation Plan (HCP) lands were not clipped out of the data.


These data represent critical habitat designated (February 24, 2016, 81 FR 9252) under the Endangered Species Act for the Lower Columbia River coho salmon ESU.

Process Steps

Process Step 1

CC ID: 1082029

Data creation process 2013 - 2016.


Critical habitat data were derived from fish distribution data from the Oregon Department of Fish and Wildlife and the Washington Department of Fish and Wildlife.

Process Step 2

CC ID: 1082030

FCH_COLCR_Designated&Excluded_6-6-16.shp (NAD_1983_Oregon_Statewide_Lambert_Feet_Intl) geographic transformation, unprojected -> COLCR_ch.shp (GCS_North_American_1983 wkid 4269).

Geometry was edited (deleted features), attributes were not edited, metadata was edited.

Deleted features were those with Econ_Excl = “Exclude - Economic Impacts” (i.e., removed economic exclusion features that were not designated).

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

Process Step 3

CC ID: 1082031

The 2019 version COLCR_ch.shp (GCS_North_American_1983 wkid 4269) was converted into the standardized feature class SalmonCoho_LowerColumbiaRiverESU_20160224 (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 metadata from the source FCH_COLCR_Designated&Excluded_6-6-16.shp (NAD_1983_Oregon_Statewide_Lambert_Feet_Intl).

Migrated fields: "STRM_NAME" into "UNIT" (deleted value "unnamed"), "USEDESC" into "NOTES"

Dropped fields: FID, HUC5, USE, LENGTH, HCP_Excl, Econ_Excl, Final_CH
