Summary

This dataset is intended to provide GIS users with data for creating maps that depict the ESU/DPS boundary as well as the historical structure of the population. The data are based on the most recent species description found in agency regulations and published in the Federal Register. The polygons illustrate the location and extent of freshwater spawning areas occupied currently (the ESU/DPS boundary) or historically. However, these data DO NOT constitute a legal boundary or definition for this DPS. These data are based on the most recent species description found in agency regulations at 50 CFR 17.11, 50 CFR 223.102, and 50 CFR 224.101. Please see Supplemental Information for more details regarding this dataset.

Description

This dataset depicts the general boundaries of the South-Central California Coast Steelhead distinct population segment (DPS) under the U.S. Endangered Species Act, as well as the historical population structure of the species. These boundaries represent the freshwater spawning areas occupied currently and historically. Only the areas coded as Accessible (in attribute "Class") constitute the defined ESU/DPS boundary.

Use limitations

The distributor shall not be held liable for improper or incorrect use of this data, based on the description of appropriate/inappropriate uses described in this metadata document. It is strongly recommended that this data is directly acquired from the distributor and not indirectly through other sources which may have changed the data in some way. Please review the attribute data and process steps to determine appropriate depiction and item reference. This data is as correct and up-to-date, from the publication date, as possible according to the Hydrologic Unit Code (HUC) 6 boundaries. It should be noted that the boundaries shown include both the areas of the watersheds that are accessible and anthropogenically blocked, however the ESU/DPS boundaries are defined as only the areas that are accessible to the fish populations. Species do not necessarily inhabit all drainages or river reaches depicted. Constraints from the source data: These data should not be used at scales greater than 1:24,000 for the purpose of identifying hydrographic watershed boundary feature locations in the U.S.A. Photographic or digital enlargement of these maps to scales greater than that at which they were originally delineated can result in misrepresentation of the data. If enlarged, the maps will not include the fine detail that would be appropriate for mapping at the small scale.

Supplemental information
The original spatial dataset representing this DPS' boundary was created in 1994. This updated dataset incorporates a significant review, revision, and refinement of the boundary using more recent watershed and species' distribution data layers. Specifically, NOAA Fisheries used the 6th field hydrologic unit polygon spatial dataset from the U.S. Department of Agriculture, Natural Resources Conservation Service, National Cartography and Geospatial Center (12-Digit Watershed Boundary Dataset (WBD), 2009, 1:24,000, http://www.ncgc.nrcs.usda.gov/products/datasets/watershed/) to build the freshwater boundaries for this and other salmon and steelhead DPSs listed under the U.S. Endangered Species Act in California, Oregon, Washington, and Idaho. NOAA Fisheries also reviewed barrier information for each DPS including (for California) the Passage Assessment Database (Pacific States Marine Fisheries Commission, September 2010, http://www.calfish.org) NOTE: The boundaries contained in this dataset focus specifically on watersheds known to currently or historically support spawning habitat for each ESU/DPS. Other downstream areas used for rearing and migration to/from the ocean are NOT necessarily included within these boundaries. Also, while the ESU/DPS is known to occur within the general boundary depicted in this dataset, it does not necessarily inhabit all river reaches within the boundary. The dataset was developed based on each species' legal description (found at 50 CFR 17.11, 50 CFR 223.102, and 50 CFR 224.101) as well as the historical population structure defined by NOAA Fisheries Science Center Biological Review Teams (BRTs). Using the 6th field HUCs, watersheds within the spawning range of each DPS were identified and combined into larger polygons to form the overall boundary. HUC polygons were not altered in any manner except as noted below under "HUC CHANGES." All HUCs within the legal boundary descriptions and below identified impassible anthropogenic barriers were deemed accessible and considered part of the DPS boundary. If any part of a HUC was accessible then the entire HUC was coded as accessible. All HUCs upstream of impassible anthropogenic barriers and within the DPS historical structure recognized by the BRT have been identified as anthropogenically blocked. These areas are not contained in the legal definition but their identification contributes to an overall understanding of the species/DPS range.

Data Quality

Scope of quality information
Resource level dataset




Data quality report - Topological consistency
Evaluation method
There are no unclosed polygons, intersections without nodes, or polygons without labels or with more than one label. The ArcGIS geodatabase topology tools were used to make corrections using 11 rules including no gaps, no overlaps, identify corresponding linework for every polygon boundary, and remove duplicate lines with the same beginning and ending nodes.

Measure description
All fields for all polygons are attributed. Some polygons in the Ncontrb_a field might have a 0 value.




Data quality report - Quantitative attribute accuracy
Measure description
100% of the attributes were visually reviewed. The accuracy of this data is dependent on the level of detail of the source material and the interpretation procedures for capturing that source.




Data quality report - Absolute external positional accuracy
Dimension horizontal


Measure description
The WBD was produced using Digital Raster Graphics (DRG's) as the source map. Data completeness for DRG files reflects content of the source graphic and may therefore be reflected in the completeness and accuracy of the WBD. The map was digitized from USGS 1:24,000-scale digital raster graphic base maps, with an inherited error of +/- 40 feet according to the USGS National Map Accuracy Standards. It is estimated that any errors detected were less than 10%. It should also be noted that while general rules of hydrology were used (i.e. natural water flow is downhill), the locations of boundaries is still somewhat subjective as the 1:24,000-scale DRG's do not always provide enough information for identifying the location of the boundaries.

Description
Original dataset attribution was reviewed and revised to reflect the updates and changes made to the dataset. These revisions to the attribution were also made to ensure that the dataset met the Federal Standards for Delineation of Hydrologic Unit Boundaries. The NHD was used during this process to help with the naming and downstream coding of each unit. In some instances there were name hydrologic unit name discrepancies between the NHD and what was printed on the DRG's. In these instances the DRG's were used instead of the NHD.

Description
NOAA Fisheries used the 6th field hydrologic unit polygon spatial data set from the U.S. Department of Agriculture, Natural Resources Conservation Service, National Cartography and Geospatial Center (12-Digit Watershed Boundary Dataset (WBD), 2009, 1:24,000, http://www.ncgc.nrcs.usda.gov/products/datasets/watershed/) to build the ESU/DPS boundaries. Additionally, barrier information was considered for each ESU/DPS. The ESU/DPSs within California relied on the Passage Assessment Database (Pacific States Marine Fisheries Commission, September 2010, http://www.calfish.org) . Washington, Oregon, and Idaho used the Pacific Northwest Hydropower System Database from the Bonneville Power Administration. The legal boundary description (as published in the Federal Register) for each ESU/DPS was reviewed as well as the historical structure of the ESU/DPS as defined by NOAA Fisheries Science Center Biological Review Teams (BRT). Using the 6th field HUCs, the contributing areas of each ESU/DPS were identified and combined into larger polygons to form the overall boundary. No HUC polygons were altered in any manner. All HUCs below identified impassible anthropogenic barriers were deemed accessible and constitute the ESU/DPS boundary. All HUCs above impassible anthropogenic barriers and within the historical structure recognized by the BRT have been identified as anthropogenically blocked. These areas are not part of the legal definition but their recognition contributes to an overall understanding of the species constitution. If any part of a HUC was accessible the entire HUC was coded as accessible. The user must be aware and review the written description of the ESU/DPS as well as examine the area of interests location in relation to nearby barriers in order to determine if that area is within or outside of the ESU/DPS. Notes for this ESU/DPS:

When the process occurred 2005-01-01
Description
The new WBD dataset was reviewed on-screen by USGS, EPA, or NRCS personnel using DRG's and DOQ?s as base maps. Hydrologic Units that were under 10,000 acres (for the 12-digit units) and 40,000 acres (for the 10-digit units) were reviewed and if possible were dissolved out. Along the coastal areas classic watersheds that fell within the federal guidelines size criteria (12-digit: 10,000-40,000 acres, 10-digit: 40,000-250,000 acres) were broken out. If possible the remaining frontals were left as their own units. Frontals that did not meet the size criteria were grouped together with other frontals within the overall 8-digit or 10-digit unit. Hydrologic units what were greater than 40,000 acres (12-digit units) and 250,000 acres (10-digit units) were reviewed. If possible these unit where then broken down into smaller units that met the size criteria. In some cases additional breaks within the unit would not have made sense or have been very useful (example: When the majority of the unit was made up by a major waterbody feature such as a lake or reservoir and the surrounding tributaries were too small to break out as their own unit). In these instances the unit was left big. Source_Used_Citation_Abbreviation: USGSDRG
