Water Quality

County-Wide Information and Education Effort, Polk County, WI

Often times people want to do everything they can to protect their lake, but don’t realize that everything they do affects the lake. So our list of how to help is simple, and so are the reasons: to ensure recreational opportunities, preserve scenic beauty, and

protect plant and animal communities now and for tomorrow.

These three posters were developed by the Polk County Association of Lakes and Rivers, the Polk County Land and Water Resources Department, and the Wisconsin Association of Lakes with funding by a Lake Planning Grant by the Wisconsin Department of Natural Resources.

The posters are available for reprint

in their entirety. You may download the pdf files (requires Adobe Reader) and display the poster, or publish as a page in your newsletters or other publications. Files are provided in 8.5"x11" size, grayscale or full color. High resolution files for 4-color printing in 17"x22" sizes are available on CD. Call Polk 715-485-8637 for more information or for help with your own education effort.

Shoreland Protection

The most important environmental and economic assets to Polk County are its water resources. These resources provide us with safe, clean drinking water, recreation opportunities, habitat for fish and wildlife, and intrinsic beauty.


An emphasis has been placed on aquatic insect and other macroinvertebrate studies over the last three decades. These organisms are very useful indicators of biological integrity and water quality as they are found in nearly all aquatic and semi-aquatic habitats.


Aquatic macrophytes (not weeds) are higher order vascular plants - that is they have connecting cells to transport nutrients and liquid through their stems.
