    1.2 Description
      1.2.1 Abstract:
                    The Non-Navigational Dam Coverage provides mapped
                    locations of non-navigational dam sites.  It also
                    includes an ordered database of information linked
                    to these mapped facilities. Coverage is provided
                    on dams not associated with commercial navigation.
                    These dams may be used for a variety of purposes,
                    including public water supply, power generation,
                    flood control, irrigation and recreation. 
                    Responders must be aware of dam locations, because
                    oil recovery becomes more difficult after passage
                    over a dam spillway, even with dams that may be
                    considerably smaller than commercial navigation
                    structures. This coverage helps to bring such
                    sites in the Minnesota counties of Cook, Lake, St.
                    Louis, and Carlton, and the Wisconsin counties of
                    Douglas, Bayfield, Ashland, and Iron to the
                    attention of spill planners and responders. The
                    location of these sites were obtained and quality
                    assured/quality controlled using maps and
                    individual feedback from various public agencies
                    and private sector groups regarding specific
                    sites.
      1.2.2 Purpose:
                    In order to better protect unique commercial,
                    environmental, and cultural resources from oil
                    spills, the Oil Pollution Act of 1990 mandated a
                    coordinated effort by federal, state, and local
                    regulatory agencies and the regulated community to
                    enhance oil spill preparedness and response.  This
                    coverage provides the location and attached data
                    for the 8 counties of the Western Lake Superior
                    Mapping Area.  The development of spatial
                    databases and geographic information systems is
                    done pursuant to implementing the preparedness and
                    response mandates of the Oil Pollution Act of
                    1990.
      1.2.3 Supplemental Information:
                    These data were prepared at map scales of 1:24,000
                    and are best used in applications of comparable
                    resolution.  In addition, these data were
                    developed to meet specific project objectives
                    related to contingency planning and spill response
                    and therefore may not represent exhaustive feature
                    inventories.

  2 Data Quality Information
    2.1 Attribute Accuracy
      2.1.1 Attribute Accuracy Report:
                    Great Lakes Commission staff working on the Area
                    Contingency Planning project verified all
                    descriptive and spatial attributes and collected
                    confirmation from owners/operators of attributes. 
                    Spatial data were cross-checked with multiple
                    sources. Quality assurance and quality control for
                    the data were developed utilizing in-house
                    standard operating procedures.
    2.2 Logical Consistency Report:
                    Data were developed for this layer utilizing
                    primarily federal resources regarding the dam
                    sites. These primary sources include the U.S. Army
                    Corp of Engineers' National Inventory of Dams
                    database, USGS 7.5 minute quadrangle maps,
                    federal, state, local and private owner/operators
                    hard copy and electronic sources; and an
                    exhaustive external review process performed by
                    the primary holders of data.  Initial data were
                    supplied by federal agencies maintaining dam
                    records nationally in hard copy and electronic
                    format.  Data was reviewed for location and
                    accuracy at the scale of 1:24,000 on appropriate
                    base maps.  Location and attribute information is
                    only as accurate and complete as the information
                    specifically applies to each individual record at
                    the time of data development.  Data for these
                    facilities are primarily attributed points,
                    plotted in ArcView 3.1 GIS.  These points were
                    generated in 1999 and updated in 2000 based on
                    current information from primary sources but do
                    not necessarily always exactly overlay the base
                    map 7.5 minute quadrangle maps with previous
                    publication dates.
    2.3 Completeness Report:
                    This coverage does not necessarily include all
                    dams within the given Western Lake Superior
                    Mapping Area.  Primarily, the federal and state
                    regulatory agencies overseeing these facilities
                    provided the initial data source for these
                    facilities.  Please note that not necessarily all
                    facilities within the Western Lake Superior
                    Mapping Area were included in the federal and
                    state regulatory agencies' initial data. This
                    layer represents available data as of 2000.  
                    Exhaustive efforts were made to compile as
                    thorough an atlas as possible.
    2.4 Positional Accuracy
      2.4.1 Horizontal Positional Accuracy
        2.4.1.1 Horizontal Positional Accuracy Report:
                    Horizontal positional accuracy is tested by visual
                    comparison of hard copy check plots to the source
                    materials and verifying the location of the data
                    on screen relative to other data layers in the
                    same geographic area.

      2.5.2 Process Step
        2.5.2.1 Process Description:
                    Locational information and the attached database
                    information for the dam coverage were primarily
                    obtained from the U.S. Army Corp of Engineers,
                    National Inventory of Dams.  Address cross
                    verification, updating and correction were done
                    through the use of online sources.  Additional
                    site and locational information verifications were
                    obtained from state and local land management
                    agencies and government agencies including the
                    Department of Natural Resources online site for
                    Minnesota and Wisconsin.  In addition, the DeLorme
                    Atlas and Gazetteer and U.S. Geological Survey 7.5
                    minute quadrangle maps for was reviewed for site
                    identification and verification.  Point shape
                    files for each non-navigational dam were entered
                    directly into ArcView version 3.1 Geographic
                    Information System (GIS) software and displayed
                    against Digital Raster Graphic (DRG) imagery of
                    1:24.000 scale U.S. Geological Survey topographic
                    maps.  Data links were incorporated into these GIS
                    files to match the non-navigational dam data and
                    to appropriate data records providing contact,
                    locational, and commentary information. Draft hard
                    copy atlases were prepared from this data,
                    supplied by the Great Lakes Commission, and the
                    USGS's Upper Midwest Environmental Sciences Center
                    (UMESC) in Onalaska, Wisconsin.  The UMESC
                    produced hard copy maps in portable document files
                    (.pdf) format at scales of  1:25,000 and
                    1:100,000.  These maps were then reproduced 
                    and distributed by the Great Lakes Commission 
                    for external review by primary source data 
                    holders.  All updated, corrected, and amended 
                    information was then added to the project files and 
                    returned to UMESC for final Atlas distribution 
                    in .pdf hardcopy format; and electronic
