Item Identification

Title: Chinook Salmon (Sacramento River winter-run ESU) polyline
Publication Date: 2016-01-21

The following waterways, bottom and water of the waterways and adjacent riparian zones: The Sacramento River from Keswick Dam, Shasta County (River Mile 302) to Chipps Island (River Mile 0) at the westward margin of the Sacramento-San Joaquin Delta, all waters from Chipps Island westward to Carquinez Bridge, including Honker Bay, Grizzly Bay, Suisun Bay, and Carquinez Strait, all waters of San Pablo Bay westward of the Carquinez Bridge, and all waters of San Francisco Bay (north of the San Francisco/Oakland Bay Bridge) from San Pablo Bay to the Golden Gate Bridge.Adjacent riparian zones are those areas above a streambank that provide cover and shade to the nearshore aquatic areas. This designation does not include any estuarine sloughs.


These data represent critical habitat designated (June 16, 1993, 58 FR 33212) under the Endangered Species Act for the Sacramento River winter-run Chinook salmon ESU.

These river/stream (line) data should be used in conjunction with estuary (polygon) data in the SalmonChinook_SacramentoRiverwinterrunESU_19930616_poly feature class.

CFR notes this critical habitat was "redesignated and amended at 64 FR 14067, March 23, 1999" - this final rule made no substantive changes to the existing regulations; it made regulations more concise, better organized, and easier for the public to use.2021-05-17T00:00:00Endangered Species Act critical habitat spatial data clarifications


Process Steps

Process Step 1

CC ID: 1081650

Data creation process 2016.

SacramentoRiverWinterRunCriticalHabitat.gdb -> SacramentoRiverWinterRunCriticalHabitat_Riverine (feature class)

Process Date/Time: 2016-01-21 00:00:00

Process Step 2

CC ID: 1081651

SacramentoRiverWinterRunCriticalHabitat_Riverine (feature class) (NAD_1983_UTM_Zone_10N wkid 26910) geographic transformation, unprojected -> CKSAC_ch_riverine.shp (GCS_North_American_1983 wkid 4269).

Geometry was not edited, attributes were not edited, metadata was edited.

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

Process Step 3

CC ID: 1081652

The 2019 version CKSAC_ch_riverine.shp (GCS_North_American_1983 wkid 4269) was converted into the standardized feature class SalmonChinook_SacramentoRiverwinterrunESU_19930616_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 metadata from the source SacramentoRiverWinterRunCriticalHabitat_Riverine (feature class) (NAD_1983_UTM_Zone_10N wkid 26910).
