The Wisconsin DNR maintains a very nice page with links to countywide trout stream maps. Both black & white and color maps are available that show the location and stream classification. The DNR page also contains direct links to online interactive maps for additional stream information.
The angular difference between the geographic and the magnetic meridians at a point on the earth is called magnetic declination. The values for magnetic declination in Wisconsin vary today from -4.0° in Door County to +1.5° in the west-central part of the state. While these values are not as great as the +20° declination in Seattle, Washington, they are still of concern to surveyors, map makers and navigators, and others who use maps or compasses.
The Sanborn Fire Insurance Maps are a valuable resource for genealogists, historians, urban planners, teachers or anyone with a personal connection to a community, street or building.

A variety of map types include a representation of the PLSS. These maps cover a range of scales and accuracies.
We offer a variety of digital outline maps for use in various graphics, illustration, or office software. The map graphics available for download have been derived from several common layers of digital GIS data. All of the statewide GIS data layers used were processed by state agencies and exist in the Wisconsin Transverse Mercator coordinate system.
There are several sources for Wisconsin County Maps. Below we have included some information and links to pertinent map sources.
