Abstract

Critical habitat includes all marine waters within the delineated boundaries. For the inland waters of Washington state (2006 designation), the contiguous shoreline is defined by the line at a depth of 20 feet (6.1 meters) relative to extreme high water. For the coastal marine waters along the U.S. west coast (2021 revision), the contiguous shoreline is defined by the line at a depth of 20 feet (6.1 meters) relative to mean high water. See the final rules (71 FR 69054 and 86 FR 41668) for descriptions of areas excluded from this critical habitat designation. For the inland waters of Washington state (2006 designation), military areas excluded due to national security impacts were not clipped out of the data.For the coastal marine waters along the U.S. west coast (2021 revision), military areas excluded due to national security impacts (i.e., the Quinault Range and its 10 kilometer buffer) were clipped out of the data.

CC ID: 1114543
Description:

Data creation process 2006.

SRKW_FCH_11_14_06_NAD83.shp

The areas designated include all marine waters deeper than 20 feet (6.1 meters) relative to a contiguous shoreline delimited by the line of extreme high water. A consistent 20-foot depth contour was not available at the time these data were developed. Therefore, the shoreline depicted in these data was developed from shorezone inventory linework available from the Washington Department of Natural Resources, with modifications made to delineate separate marine zones and to remove areas associated with river inlets, channels, and other waterways considered too shallow to be occupied by killer whales. The U.S. Exclusive Economic Zone available from NOAA, Washington county linework available from the Interior Columbia Basin Ecosystem Management Plan, and digital 1:24k/1:100k topographic maps depicting bridges were also used to define area boundaries.

Modified Washington Department of Natural Resources shorezone linework to remove shallow water areas (e.g., small inlets) in consultation with Lynne Barre (NOAA Fisheries, killer whale critical habitat project leader). In re-evaluating the nearshore areas proposed for critical habitat, several small or shallow inlets, harbors, coves and bays, some with very narrow entrances were identified. More detailed sighting information was obtained to assist with drawing a shoreline boundary for some areas. In most cases, the whales had not been sighted within the small water bodies (e.g., Drayton Harbor, Wescott Bay, Guthrie Cove, Tulalip Bay, Port Gardner/eastern side of Jetty Island, Tacoma Yacht Club, Chapman Bay, Big Fishtrap Inlet, Gull Harbor, Rocky Bay at the mouth of Rocky Creek, Taylor Bay, Mayo Cove, Horsehead Bay, Wollochet Bay, Mystery Bay, Eagle Harbor, Jarrell Cove and Sequim Bay), so the data were modified to excise these areas in the final designation. Several small harbors where there were reports of Southern Resident killer whales at the harbor entrances (e.g., Keystone Harbor, Gig Harbor) were included in the final designation and in the data.

Process Step 4

CC ID: 1114546
Description:

Data creation process 2019 - 2021.

SRKW_Coastal_CH_Final_2021-07-26.shp

For 2021 ch revision only, Pacific Ocean data.

Step 1 - Select the California - Oregon - Washington length of the CUSP shoreline and clip the streams, rivers, enclosed bays, and other shoreline intrusions so that they align with the shoreline north and south of these openings in order to simplify the shoreline. Split the California length from the Oregon - Washington length. Shoreline irregularities caused by intrusions like tributaries and enclosed bays were removed to avoid the unbalanced affect they would have on the TIN surface interpolation process.

Step 2 - Select 200 m isobath from the Carowall bathymetry data set and create a separate layer. Then clip off parts of it north of the US-Canada maritime border and south of latitude 36 deg 18’. This is a selection of an isobath that will be used later to delineate the seaward extent.

Step 3 - Convert bathymetry polygons in bathpy_or.shp and bathpy_wa.shp into isobath lines for Washington and Oregon, using the features to lines tool. Bathymetry polygons need to be separated into their component upper and lower value isobaths in order to be used to interpolate a surface from which the 6.1 m isobath can be generated.

Step 4 - Combine the CUSP shoreline for Oregon and Washington with the 10 m isobath along those two states. Manually adjust any gaps in a way consistent with the position and direction of the isobaths before and after the gaps. This prepares the isobaths so that a TIN interpolation may be run on them.

Step 5 - Use the Oregon and Washington contour layers, which contain 0 and 10 m isobaths, to generate a TIN surface using ArcGIS spatial analyst, then use the spatial analyst contour tool to generate a 6.1 m isobath from that TIN surface. This produces the shoreward extent along the Oregon and Washington coast, at a depth of 6.1 m.

Step 6 - Extract the 5 and 10 isobaths along California's coast from Contour_5m.shp and combine it with the California segment of the CUSP shoreline. This prepares the isobaths so that a TIN interpolation may be run on them.

Step 7 - Use the layer with combined CA CUSP shoreline (0 m) and the 5 m and 10 m isobath layer to generate a TIN surface using ArcGIS spatial analyst, then use the spatial analyst contour tool to generate a 6.1 m depth isobath from that TIN surface. This produces the shoreward extent along the California coast at a depth of 6.1 m.

Step 8 - Where the 6.1 m isobath intrudes into rivers, bays, and other outlets that lead to the sea (Strait of Juan de Fuca, Columbia River, San Francisco Bay), intrusions were cut off in front of the waterway by drawing a line from the part of the 6.1 m isobath north of the waterway’s entrance to the part of the isobath south of the waterway’s entrance.

For the Strait of Juan de Fuca, this cut was made from Cape Flattery to Tatoosh Island, then from Tatoosh Island to the US – Canada maritime border on a bearing to Bonilla Point, on Vancouver Island, Canada. For the Columbia River, this cut was made from the seaward end of jetty on the northern side of the river to the seaward end of the jetty on the southern side of the river. Monterey Bay was not cut because it is a very broad bay above a very deep sea channel that whales frequently enter. For San Francisco Bay, this cut was made from where the 6.1 m isobath begins to veer into the bay, off Bonita Point, then down toward Gorman Island, where it connects with the isobath as it emerges from the bay and begins to turn south along the California coast. Diversions upstream or into enclosed bays, often caused by channel flow or dredging, are not seen to be representative of SRKW critical habitat just on account of their depth.

Data creation process 2019 - 2021.

SRKW_Coastal_CH_Final_2021-07-26.shp

For 2021 ch revision only, Pacific Ocean data.

Step 9 - Modify the 6.1 m isobath to conform with the detailed CUSP shoreline. Original isobaths of 5 and 10 m depths that were used to generate the TIN surface (and from it the 6.1 m isobath) along the California coast sometimes crossed over the actual CUSP mainland shoreline. Because the CUSP shoreline is considered more accurate than the bathymetric data, its position takes precedence over the location of the bathymetry and the isobath was adjusted to pass around the shoreline in areas where it otherwise would cross over the shoreline. This adjustment was made anywhere the TIN-generated isobath intersected the coastline of the mainland. A horizontal buffer of 6.1 m, was added to keep the isobath at a horizontal distance away from the shore equal to the depth of SRKW critical habitat at its shoreward extent as a margin of error. Inaccuracies of original bathymetry resulted in locations where the bathymetric isobaths appear to cross over the coastline of the mainland. Moving the inshore isobath to a position seaward of these crossovers prevents orca habitat from appearing to include upland areas, and a slight buffer along these areas that pushes the isobath further out removed the assumption that SRKW habitat would go right up to the shoreline.

Step 10 - Combine the 200 m isobath, representing the seaward extent, with the 6.1 m isobath, connecting them together in the north along the US-Canada maritime boundary, and in the south along the 36 deg 18' latitude (Point Sur), then convert these lines into a polygon. This polygon represents the coastal extent of SRKW critical habitat.

Step 11 - Split this polygon along 4 latitudes: Cape Meares, OR (45 deg 29' 12" N); California - Oregon Border (41 deg 59' 55" N); Cape Mendocino, CA (40 deg 26' 19" N); Pigeon Point (37 deg 11' 00" N) to create 5 polygons. These latitudes represent the locations where SRKW critical habitat is divided into 5 different areas.

Step 12 - Split the northernmost polygon, between the US – Canada border and Cape Meares, using the 50 m isobath from the Washington and Oregon bathymetry data sets. This will create 2 zones, an inshore zone from 6.1 m to 50 m depths and an offshore zone from 50 m to 200 m depths. This division represents two distinct SRKW critical habitat areas.

Step 13 - Clipped out the excluded Quinault Range Site (QRS), and a 10 km buffer, for all areas that were not within the Olympic Coast National Marine Sanctuary (OCNMS).
