Originator Minnesota State University, Mankato, Water Resources Center
Title Minnesota River Basin Lakes (mrblake)
Abstract The Minnesota River Basin Lakes (mrblake) represent the surface water drainage system of the Minnesota River Basin. The data file consist of lakes and other ponded water bodies published on the USGS 24,000 scale topographic quadrangle maps.
Purpose These data were developed to provide a consistent GIS lake layer for the Minnesota River Basin.
Time Period of Content Date 1958 - 1994
Currentness Reference For any given area, the most recent USGS 7.5-minute quadrangle available at that time was used for digitizing the data.
Progress Complete
Maintenance and Update Frequency As needed
Spatial Extent of Data 12 major watersheds of the Minnesota River Basin.
Bounding Coordinates -97.364
-93.087

Data Quality Information - - - - - - Go back to top
Attribute Accuracy The following attribute accuracy control checks have been performed: manual comparison of the hard copy topographic quadrangle maps with the computer digital display; comparison using USGS digital raster graphic images as a background to the line feature coverage and polygon attribute data.
Logical Consistency Data are topologically correct within ArcInfo 7.1.2. All intersecting arcs contain nodes and all polygons contain label points.
Completeness All polygon features representing lakes or ponds on USGS 24000 series quadrangle maps were digitized for the Minnesota River Basin. All polygons and lines are attributed.
Horizontal Positional Accuracy Not available
Lineage The following description is for lake and pond features in the following counties: Blue Earth, Brown, Cottonwood, Faribault, Freeborn, Jackson, Le Sueur, Martin, Nicollet, Sibley, Steele, Waseca, and Watonwan.

All polygon features on the USGS quadrangle maps, representing lakes or ponds, were digitized using AutoCAD Release12 on a Calcomp 9100 digitizing table at Water Resources Center, Minnesota State University, Mankato (MSUWRC). The data were imported into ARC/INFO and edited for node dangles and intersectarc errors, then built as a polygon coverage.


The following description is for lake and pond features in the following counties: Big Stone, Carver, Chippewa, Dakota, Douglas, Grant, Hennepin, Kandiyohi, Lac qui Parle, Lincoln, Lyon, McLeod, Murray, Otter Tail, Pipestone, Pope, Ramsey, Redwood, Renville, Rice, Scott, Stevens, Swift, Traverse, and Yellow Medicine.

Linework from Mn/DOT (State of Minnesota Basemap 98) lake data file were visually compared with hard copy topographic quadrangle maps and USGS digital raster graphic images. Linework that closely followed the shorelines of waterbodies was accepted and incorporated into the lake data file. Linework from Mn/DOT (State of Minnesota Basemap 98) that was not acceptable was deleted and digitized using AutoCAD Release12 on a Calcomp 9100 digitized table at Water Resources Center, Minnesota State University, Mankato.

A complete lake coverage was compiled by appending Mn/DOT and MSUWRC line work.
