In Wisconsin, water is an essential part of our natural heritage.  Our lakes, rivers, streams and groundwater provide us with clean water to drink, diverse habitats for fish and wildlife, places to fish and swim, vibrant economic opportunities, and a beautiful landscape. 

Our Clean Water programs focus on:

  • Landscape scale solutions.

  • The prevention and control of invasive species.

  • The importance of our groundwater resources.

With support from the Wisconsin Dept. of Natural Resources, Glacierland is conducting county-wide aquatic invasive species outreach programs in Manitowoc and Sheboygan counties.


The program coordinator educates municipal staff, lake associations, boaters and the general public on AIS issues as well as monitoring populations. A Clean Boats, Clean Water program is conducted by Glacierland’s boat inspectors and volunteers each boating season.

Aquatic Invasive Species Control


Glacierland partnered with Ozaukee County Land & Water Dept. to map the presence of phragmites and japanese knotweed across the county. The mapping provided the basis for efforts to control non-native Phragmites on private and public lands and Japanese knotweed control in road right of ways across the county.  This work will help maintain the integrity of the water resources in Ozaukee County by preventing the spread of these invasive species, and is an expansion of control efforts in adjacent counties. 

On-Farm Gypsum Demonstration

Glacierland worked with the Great Lakes Commission and We Energies to conduct gypsum demonstrations on farms in the Upper East, and Middle and Upper Duck Creek watersheds.


The effects of gypsum on water infiltration and soil structure were investigated. Gypsum may be a potential alternative to decrease soil erosion, downstream sedimentation and phosphorus loading into Green Bay and Lake Michigan.

One of the demonstration sites is at Brickstead Dairy, a fifth-generation dairy farm in Greenleaf, WI. Owner/operator Dan Brick sees the project as a way to better understand the role gypsum has on protecting groundwater resources. "Conservation will help secure a future in dairy farming in northeast Wisconsin," he said.
