California Department of Fish and Game 20020808 vector digital data https://wildlife.ca.gov/Data/BIOS https://filelib.wildlife.ca.gov/Public/BDB/GIS/BIOS/Public_Datasets/001_099/ds077.zip Results of in-stream habitat surveys (Downie et al 1998 method), summarized by stream reach, for DFG surveys conducted between 1994 and 2001 (inclusive) in the Russian River Basin (CalWater 2.2.1 hydrologic area), Central Coast Region. Sampled habitat parameters, including pool type, frequency and depth; substrate class; bank vegetation composition and canopy closure; and in-stream cover, were measured at the unit scale and summarized to stream reach. Intended for salmonid habitat restoration planning at a scale between the habitat unit level and the entire tributary level, with a focus on the geomorphic reach. These data should be particularly useful for selecting potential restoration sites based on their habitat data. In addition, we are using this approach because the geomorphology of streams has an important effect on availability and type of salmonid habitat, and also influences what types of restoration projects are appropriate. A "reachsum" database of reach-level attribute data was originally created in June, 2000 by Bob Coey, then the California Department of Fish & Game (DFG) Russian River Basin Planner, using "reachsum.prg" add-on to the "Habitat" Dbase program (this add-on was written by Ken Bunzel in the mid-1990s). This initial database summarized the in-stream habitat data collected by DFG-supervised field crews from 1994 to 1997. The reachsum Dbase program took the 1994-1997 habitat surveys database files and summarized them at the Rosgen geomorphic reach level, as labeled by the field survey crews and recorded in the database files. The data collected through habitat surveys conducted from 1998 to 2001 were processed into a second "reachsum" database using a Microsoft Access 2000 extension written by Zeb Young, a University of California GIS Analyst located at the Hopland Research & Extension Center. The 1994-1997 habitat surveys were then reprocessed with the Microsoft Access extension. The Access 2000-based reachsum extension calculates additional useful reach-level information, and recalculates previously calculated statistics, now weighting individual habitat unit attributes by habitat unit length/area when calculating summary statistics (please see the attributes section for additional information). The salmonid habitat database files were also matched to a routed GIS layer of 1:100,000 streams (created by Mike Byrne at DFG in the mid-1990s, and revised by Colin Brooks and Zeb Young) using the Arc/Info dynamic segmentation process. Mike Byrne did the dynamic segmentation for most of the 1994 to 1997 salmonid habitat surveys. Colin Brooks, Jeff Opperman, Emily Heaton, Jake Newell, Eli Asarian, and Zeb Young did the dynamic segmentation for the 1998 to 2001 data. The 1998 and 1999 surveys were calibrated using field maps to provide greater position accuracy of habitat units and channel type locations. Habitat surveys done during 2000-2001 had approximately every 10th habitat unit location recorded with a Garmin GPS unit, and these data points were used to create a more precise calibration of the habitat surveys to the underlying GIS streams layer. Towards the end of the processing of the 2000 data, a more detailed 1:24,000 streams layer became available from the California Department of Forestry and Fire Protection as part of the North Coast Watershed Assessment Program, and we started using that layer for dynamic segmentation. The habitat surveys were done from 1994 to 2001, with most surveys being done by the California Department of Fish & Game and AmeriCorps field crews, and some (mostly in 1997 and 2001) by the Sonoma County Water Agency. Habitat surveys are continuing in 2002, and these data will be added to the reachsum database and GIS layer when they become available, sometime in late 2002. The dynamically segmented ArcView shapefiles were merged into a single layer. A unique identifier for each reach was derived by combining a stream's Primary Name Code (Pnmcd) with the reach number for each survey, as labeled from the start of the survey (01 for the first reach on a stream, 02 for the second, etc.). Where the Primary Name Code was not available, one was generated using the GNIS_ID field from the USGS Global Names Information System data layer, or one was generated using a combination of the data entry person's initials, that day's date, and the number of new Primary Name Codes created that day. The data was dissolved on this unique reach identifier (REACHID), resulting in a new layer called "reachsum-dissolve.shp". The same REACHID identifier was calculated for the reachsum database. The reachsum GIS layer and reachsum database were joined in ArcView using the REACHID field. As of August 21, 2002, there are 450 reaches in the reachsum GIS layer. This number does not include an approximately 70 additional reaches that will be added when all of the 2001 data has been entered. People using the reachsum GIS layer and database should link the two using this REACHID field when using the reachsum data, unless they are using the UTM-NAD83 version, where the shapefile and database file are already merged. 20020808 publication date In work Irregular -123.366469 -122.548460 39.361439 38.347809 None salmon anadromous fisheries endangered species chinook coho None central coast russian river No restrictions Appropriate uses include planning, restoration project priorities, etc. Should not be used for habitat feature (e.g. pool) level management purposes.Disclaimer: The State makes no claims, promises, or guarantees about the accuracy, completeness, reliability, or adequacy of these data and expressly disclaims liability for errors and omissions in these data.

Yountville CA 707-944-5582 bcoey@dfg.ca.gov Bob Coey and Colin Brooks Unclassified Version 6.2 (Build 9200) ; Esri ArcGIS 10.6.1.9270 The underlying creek layer for most of the reaches is a 1:100,000 streams network originally derived from EPA Reach File 3 streams data, which is derived from USGS 1:100,000 streams data. No greater precision is intended. 2001 data reflect the precision of the new 1:24,000 streams layer available for the Russian River. Stream sinuosity is not well represented in a 1:100,000 streams layer, so location and shape of the stream course should be used carefully. In addition, many smaller streams are missing from this database. Some streams have been added to the existing streams layer by the people doing the dynamic segmentation (mostly Mike Byrne in the mid-1990s, now primarily Colin Brooks and Zeb Young). Many attributes are averaged at the reach level, meaning that values within a reach may be higher or lower than indicated. Also, they are based on a one-time sample and do not represent a time-series of data. In addition, the dynamic segmentation process does not place the data along the stream channel with absolute accuracy, so reaches may start or stop sooner or later than indicated. Some examples have been found where a change in reach type is 100 meters (about 328 feet) above or below its field-mapped location. Most reach locations are more accurately mapped, however. Data should be verified in the field when making final selections for projects in the field. Currently, streams surveyed and included in the GIS layer cover about 60% of the salmonid streams of the Russian River; 80% coverage is anticipated when all data (1994-2002) have been processed and included. : June, 2000: Bob Coey created the original reachsum database of attribute data using the old Dbase reachsum program. August, 2000: The original reachsum GIS layer was created by Colin Brooks by combining the 1994-1997 habitat shapefiles into a single layer. February, 2001: First queries designed with Bob Coey to select potential restoration sites and reaches with high-quality habitat. March, 2001: Corrections to existing reachsum problems were started. July, 2001: Colin Brooks and Zeb Young finished the dynamic segmentation of the 1998 - 2000 data, and correct problems in the reachsum attribute database. Zeb Young rewrote the reachsum attribute program in Access 2000 and creates a new database including all the 1994-2000 habitat data at the reach level. September - October, 2001: Zeb Young reprocessed all the habitat data in the updated reachsum program and recalculated variables to obtain average reach values weighted by habitat unit length, where appropriate. February, 2002: Metadata revised to reflect additional fields and data additions. June, 2002: Partial 2001 data and revised 1997 data were added the reachsum GIS layer. New attributes fields were added. August, 2002: Metadata revised to reflect added data and fields. onLine Vector String 557 WGS 1984 Web Mercator Auxiliary Sphere PROJCS["WGS_1984_Web_Mercator_Auxiliary_Sphere",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Mercator_Auxiliary_Sphere"],PARAMETER["False_Easting",0.0],PARAMETER["False_Northing",0.0],PARAMETER["Central_Meridian",0.0],PARAMETER["Standard_Parallel_1",0.0],PARAMETER["Auxiliary_Sphere_Type",0.0],UNIT["Meter",1.0],AUTHORITY["EPSG",3857]] coordinate pair 0.0001 0.0001 meter D WGS 1984 WGS 1984 6378137.0 298.257223563 ds77 OBJECTID Primary name code.
