Abstract:
The Non-navigational Dam Coverage provides mapped locations of non-navigational dam facilities. It also includes an ordered database of information linked to these mapped facilities. Knowledge of dam facilities is imperative for a quick and effective notification and response to potential oil spill situations. This coverage helps to bring such areas of the Ohio counties of Ashtabula, Cuyahoga, Lake and Lorain, as well as a connecting portion of Pennsylvania, which includes western segments of the counties Erie and Crawford, to the attention of spill planners and responders. The location of these facilities were obtained and quality assured/quality controlled using maps and individual feedback from various public agencies and private sector groups regarding specific sites.
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 6 counties of the Central Lake Erie Sub-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.
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.

Attribute_Accuracy:
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 via surveys or direct external review. Spatial data were cross-referenced with multiple sources. Quality assurance and quality control for the data were developed utilizing in-house standard operating procedures.
Logical_Consistency_Report:
Data were developed for this layer utilizing multiple primary sources, from federal, state, and local governmental agencies and owner/operators of the lock and dam sites. These primary sources include USGS 7.5 minute quadrangle maps; federal, state, local and private land manager/owner 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 inventories 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 3.2 GIS. These points were originally generated in 1999 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. Locational and attribute information was updated during the Fall of 1999 and Winter of 2000 prior to final Atlas publication.
Completeness_Report:
This coverage does not necessarily include all potentially regulated facilities within the given sub-area. Primarily, the federal and state regulatory agencies overseeing these facilities provided the initial source and accurately portray these facilities, but not necessarily all facilities. This layer represents available data as of 1999. Exhaustive efforts were made to compile as thorough an atlas as possible. Limits of data completeness are similar to those of the U.S. Army Corps of Engineers National Inventory of Dams.

Horizontal_Positional_Accuracy:
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. Point shapefiles for dams have been placed atop the represented dam structure at the represented location of water outfall.

Process_Step:
Process_Description:
Locational information and the attached database information for the lock and dam coverage were 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 Ohio Department of Natural Resources and Pennsylvania Department of Conservation and Natural Resources and PA Fish and Boat Commission. In addition, the DeLorme Atlas and Gazetteer and U.S. Geological Survey 7.5 minute quadrangle maps for Ohio and Pennsylvania were reviewed for site identification and verification. Point shape files for each dam were entered directly into ArcView version 3.2 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 dam data and to appropriate data records providing locational information. Draft hard copy atlases were prepared form 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 the UMESC for final Atlas preparation. UMESC processed the final data for distribution in .pdf hardcopy format; and electronic distribution via CD-ROM and the Internet. Final electronic formats include ArcView 3.2 shapefiles, .e00 ArcExport files, .pdfs, and converted CAMEO/Landview files.
