Coho salmon Lower Columbia River ESU critical habitat for use in ESA/FIFRA consultations

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.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.

This spatial data file was modified from NMFS’s “agency-official” species critical habitat data to aid in the ESA/FIFRA section 7 pesticide consultation process. For example, existing data were adapted to incorporate associated watersheds where applicable, based on the USGS Watershed Boundary Dataset HUC-12 data (https://www.usgs.gov/national-hydrography/watershed-boundary-dataset). The modifications to the NMFS critical habitat spatial data make the data more compatible for future analyses with EPA’s Use Data Layers (UDLs). The following “Description” is from the original, “agency-official” data that was used to make this HUC-based map. Most of the metadata record for this species matches the “agency-official” record; however, NMFS added a new "Citation", "File Identifier", “Credits”, “Point of Contact”, and “Lineage Process Step” that are unique to this HUC-based critical habitat data.

These data are not the official legal definition of critical habitat. The Code of Federal Regulations (50 CFR 226.212) is the source for the legal definition of the critical habitat designation.
