Summary

This layer was created to depict Critical Habitat for Steelhead in the California Central Valley ESU. The layer represents areas designated for Critical Habitat and the habitat quality in the region. It is best suited for mapping those properties in the aforementioned region.

Description

This layer depicts areas designated for Steelhead Critical Habitat as well as habitat type and quality in the California Central Valley Evolutionary Significant Unit (ESU - a "distinct population" of Pacific salmon defined as a "species" under the Endangered Species Act). These data represent the stream segments identified as Critical Habitat by the National Marine Fisheries Service (NOAA Fisheries) Southwest Regional Office (SWR). The linework for this layer is based on the California Department of Fish and Game (CDFG) and Pacific States Marine Fisheries Commission (PSMFC) 1:100,000 scale stream based routed hydrography. SWR biologists divided the routed hydrography into stream segments using the best available information to represent local Steelhead distribution and habitat. As a result, each segment has its own unique identifier (GIS_Link) and related presence and habitat information. The data set is in shapefile format and can be included as a map layer in a GIS. This data set is an updated, final version of 'CCV_Steelhead_Proposed_Critical_Habitat'. This GIS layer is part of a larger mapping effort to define the anadromous distribution and to designate critical habitat in five steelhead ESU's and two Chinook ESU's in California. Several NOAA Fisheries offices participated in this effort. As a result, although the same issues were addressed within each ESU, the offices chose differing approaches to define and populate the habitat attributes. The consequence is that there are some slight differences in the attribute tables between the coastal ESUs and the Central Valley ESUs.

Data Quality

Scope of quality information
Resource level dataset




Data quality report - Completeness omission
Measure description
This data set is in final form. Occupancy and habitat designations are based on a 1:100,000 hydrography data layer. Therefore, any streams not visible at that scale were not included in the designation process.




Data quality report - Absolute external positional accuracy
Dimension horizontal


Measure description
The positional accuracy of each designated stream segment varies with the amount of information available for that particular stream reach, as well as the precision with which the stream segment's upper and lower extents were marked on the paper maps, and how accurately that information was transferred into a digital format. The positional accuracy is also dependent on the basemap data used in the process. The stream segment determinations can be no more accurate than the CDFG 1:100,000 hydrography layer they are based on. As a result, this data set is not suitable for any type of high-precision measurement applications.




Lineage

Process step
Description
Stream segments were identified and assigned attributes by SWR biologists using CDFG 1:100,000 hydrogragraphy data and other basemap information on hard copy maps. The segments' upper and lower extents were manually marked onto the basemaps by the biologists. This information was then visually interpreted from the paper maps and entered into a digital format using the "Route Tools" extension provided by CDFG. The resulting event table was then used with the CDFG routed hydrography as the route reference to create routed events based on the biologists' segment determinations. The table containing the accompanying segment attribute information was joined using 'GIS_Link' as the related field, and the shapefile 'CCV_Steelhead_Draft_2004' was created from the routed events. To minimize errors that may have occurred during the process, the completed digital file was compared against the marked maps for consistency. The biologists also reviewed the completed digital file to ensure attribute information was associated with the correct stream segments. Biologists rated each Calwater (California Watershed Map) Hydrologic Sub-area (HSA) based on occupancy and habitat quantity and quality information found in the Steelhead distribution shapefile (CCV_Steelhead_Draft_2004). These biological ratings were compared against economic values given to each HSA. Based on whether selected criteria were met, an HSA was determined to be included or excluded from Critical Habitat. All stream segments were then coded to reflect their HSA's designation. The only exceptions to this occurred when a stream segment was valued as a migration corridor (the segment would be included as Critical Habitat even if the HSA was excluded) or if there were other overriding biological considerations. Those segments coded as Critical Habitat were then extracted from the distribution shapefile and placed in the resulting 'CCV_Steelhead_Proposed_Critical_habitat' file. Public comments were received following draft publication of the Critical Habitat Proposed Rule in December 2004. These comments were incorporated into the data set and the final critical habitat file 'CCV_Steelhead_CH_06_2005' was created.

* Data type String
* Width 35
* Precision 0
* Scale 0
Field description
This field was used by SWR biologists to assist in designating which basin the segment was located in. Basins were determined by the SWR biologists by identifying the ultimate stream/river that flows into the ocean or bay. For example, any stream that ultimately flows into the Eel River and thence into the Pacific Ocean would be attributed as belonging to the "Eel River" basin. Standardized hydrographic boundary information (e.g., USGS Hucs, CalWater) were not used to populate this attribute; rather, the biologist's local and field knowledge were employed to develop this basin referencing system.
