Description  
    Abstract
    6th field watershed layer (sub-watersheds or drainages) corresponding
    to 12 digit huc.
     
    Purpose
    USed for sumarizing information such as road density land ownership
    land uses and sub-watershed condition.
     
Supplemental_Information
    Procedures_Used
    ArcInfo was used to convert 10m contour shapefile in DEM. Grid surface
    analysis tools were then used to delineate sub-watersehd boundaries.
    The resulting data layer was then printed out and submitted for review
    by experts in the community including, the water master, and other
    members of the Tualatin River Watershed GIS Coordinating comittee.
    Comments were considered and adjustments were made to problem spots.
     
    Revisions
    Multiple revisions have been applied.
     
    Reviews_Applied_to_Data
    Standard in house quality reviews applied as well as reviews from
    experts within the Tualatin River Watershed and from members of the
    Tualatin River Watershed GIS coordinating committe.
     
    Related_Spatial_and_Tabular_Data_Sets
    Some attribute information was derrived from roads, and streams
    layers.

    Notes
    Data layer can be used to summarize additional information.  The
    Quality of the data should be considered good.
     
Time_Period_of_Content
    Currentness_Reference
    All information derrived in 1998.

 Overview_Description 
    Entity_and_Attribute_Overview 
    This data layer can be used to show many different characteristics
    based on the sub-watershed level.  Use rd_dens to display and analyze
    road densities, rsx_dens to display road stream crossing densities.
