This line shapefile represents the major tributaries of the Russian River in California. Line features have attribute codes that represent streams or shorelines. This layer is also intended for users to display major tributaries on maps without seeing all existing tributaries in the Russian River watershed. The intended purpose of this dataset is to assist in watershed planning and analysis. This layer is also intended for users to display major tributaries on maps without seeing all existing tributaries in the Russian River watershed. Circuit Rider Productions and National Oceanic and Atmospheric Administration (2002). Major Tributaries: Russian River, California, 1998-2002. Circuit Rider Productions. Available at: http://purl.stanford.edu/dj888dd7239 The hydrography layer was assembled from data originally published by the U.S. Geological Survey (USGS) in Digital Line Graph (DLG-3) format. DLG-3 data were generated by USGS from 1:100,000-scale maps by manual digitizing and raster scanning. Approximately 3200 original USGS DLG files
were processed to create the statewide hydrography data layer.
Edits to the original linework have been made during the data conversion from the original DLG-3 format to the ARC/INFO(tm) GIS format. Such changes include line movements (due to the map edge-matching process), minor corrections of attribute coding, and the closing of open polygons. Flow direction for streams (feature type line) has also been added. Stream arcs are flagged (where item FLOW = 1) to indicate whether or not the direction of a given stream (line) has been defined and/or verified.
