This polygon shapefile represents the boundary of the Russian River Watershed in California. These data are derived from the California Watershed Map (v.2.2), a set of standardized watershed boundaries meeting standardized delineation criteria.The purpose of this file is to provide GIS users with a layer of the Russian River Watershed which is not divided into smaller, sub-hydrologic units. This layer provides users with a layer that can be used to clip datasets that describe geographic regions larger than the area of the watershed.
