National Marine Fisheries Service (NOAA Fisheries) 20140109 vector digital data ftp://ftp.dfg.ca.gov/BDB/GIS/BIOS/Public_Datasets/900_999/ds982.zip http://bios.dfg.ca.gov/ 'CVSR_Chinook_Distribution_06_2005' depicts Chinook presence as well as habitat type and quality in the Central Valley Spring-run 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 Chinook 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 Chinook 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 'CVSR_Chinook_Draft_2004' This layer was created to aid SWR biologists in establishing Critical Habitat for Chinook in the Central Valley Spring-run ESU. The layer represents an approximation of Chinook occupancy and habitat quality in the region and is best suited for mapping those properties in the aforementioned region. The 'SR_Chinook_Distribution_06_2005' layer only contains known occupied stream reaches.

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 Version 6.2 (Build 9200) ; Esri ArcGIS 10.6.1.9270 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 table containing the accompanying segment attribute information was joined using 'GIS_Link' as the related field, and the shapefile 'CVSR_Chinook_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 'CVSR_Chinook_Distribution_06_2005' was created. not complete NOAA Fisheries Charleen Gavette GIS Technician mailing and physical
