National Marine Fisheries Service (NOAA Fisheries) August 2005 vector digital data \\GISMAIN\C$\fish_reproject\NC_Steelhead_Distribution_08_2005_utm.shp NC_Steelhead_Distribution_08_2005_utm 'NC_Steelhead_Distribution_08_2005' depicts Steelhead presence as well as habitat type and quality in the Northern California Evolutionary Significant Unit (ESU). The data was compiled by the National Marine Fisheries Service (NOAA Fisheries) Southwest Regional Office (SWR) in an effort to designate Critical Habitat for Steelhead in California. 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 update of 'NC_Steelhead_Distribution_06_2005' This layer was created to aid SWR biologists in establishing Critical Habitat for Steelhead in the Northern California ESU. The layer represents an approximation of Steelhead occupancy and habitat quality in the region and is best suited for mapping those properties in the aforementioned region. The 'NC_Steelhead_Distribution_08_205' layer includes information pertaining to both occupied and unoccupied stream reaches. For instance, there are some stream reaches that have habitat suitable for Steelhead rearing, but that are not occupied by Steelhead. Therefore, it is important to query the desired stream segments based on attribute information, such as occupancy, when mapping in a GIS to avoid confusion. en August 2005 publication date In work As needed -124.423776 -122.816274 41.448828 38.458984 381053.357292 515346.834142 4588370.490044 4257415.698135 ISO 19115 Topic Category Biota Environment Inland Waters Location Oceans Rivers Fish Steelhead Salmonid Oncorhynchus mykiss O. mykiss Distribution Habitat Evolutionary Significant Unit (ESU) California CA Northern California ESU Northern California None None NOAA Fisheries Charleen Gavette GIS Technician mailing and physical address

Santa Rosa CA 95404 (707)-575-6017 charleen.gavette@noaa.gov Data layers from the following were used as basemap layers or as detailed in the 'Process Description' section during the designation process: California Department of Fish and Game, Pacific States Marine Fisheries Commission,California Geospatial Information Data Library, State Coastal Conservancy, California Department of Forestry, US Geological Survey Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.1.0.722 Shapefile 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. 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. Stream segments were identified and assigned attributes by SWR biologists using CDFG 1:100,000 hydrogrography 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 Microsoft Access table containing the accompanying segment attribute information was joined using 'GIS_Link' as the related field, and the shapefile 'NC_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. 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 distirbution file 'NC_Steelhead_Distribution_06_2005' was created. Further review and refinement produced the current 'NC_Steelhead_Distribution_08_2005' dataset. August 2005 NOAA Fisheries Charleen Gavette GIS Technician mailing and physical address
