Item Identification

Title: Green Sturgeon (Southern DPS) line
Publication Date: 2009-10-05

Critical habitat in freshwater riverine areas includes the stream channels and a lateral extent as defined by the ordinary high-water line (33 CFR 329.11). In areas for which the ordinary high-water line has not been defined pursuant to 33 CFR 329.11, 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 bays and estuaries includes tidally influenced areas as defined by the elevation of mean higher high water (MHHW).No areas were deemed ineligible for designation. No unoccupied areas were designated. 14 areas based on economic impacts and 5 areas based on national security impacts were excluded from this critical habitat designation and clipped out of the data. The following tribal lands were excluded from this designation, but were not clipped out of the data:(1) Cachil DeHe Band of Wintun Indians of the Colusa Indian Community, California(2) Cher-Ae Heights Trinidad Rancheria, California(3) Confederated Tribes of the Coos, Lower Umpqua, and Siuslaw, Oregon(4) Coquille Indian Tribe, Oregon(5) Hoh Tribe, Washington(6) Jamestown S'Klallam Tribe, Washington(7) Lower Elwha Tribe, Washington(8) Makah Tribe, Washington(9) Quileute Tribe, Washington(10) Quinault Tribe, Washington(11) Shoalwater Bay Tribe, Washington(12) Wiyot Tribe, California(13) Yurok Tribe, California


These data represent the critical habitat for the green sturgeon (Southern DPS) designated under the Endangered Species Act on October 9, 2009 (74 FR 52300). These line data should be used in conjunction with polygon data, which together represent the entire critical habitat designation.

Process Steps

Process Step 1

CC ID: 1083585

The data was created by extracting stream lines from National Hydrography Dataset (NHD) medium resolution shapefile that represented green sturgeon critical habitat. This dataset's features were modified to better match up to the corresponding estuaries and were cut at locations where the NMFS Critical Habitat Review Team (CHRT) determined green sturgeon have been observed or where head of tide was determined.

Process Date/Time: 2009-10-05 00:00:00

Process Step 2

CC ID: 1083586

2009 source data converted to NMFS ESA critical habitat national standard 2020. Geometry was not edited. Attributes were edited. Metadata was copied from 1 line file GreenSturgeonCHStreams.shp
