Mukwonago River


On Saturday, May 19, SEWTU partnered with the Wisconsin DNR for a workday on the Mukwonago River just outside of Mukwonago, WI. The “Muk” is a Class II brook and brown trout steam, meaning there is some known natural reproduction occurring. It’s also one of the most ecologically diverse river systems in the state – home to over 50 different species of fish! 


Several years ago, the DNR purchased the Rainbow Springs Property through the Stewardship Program. The property was the site of the Rainbow Springs Golf Course which had gone out of business.


Later this year the DNR will be removing 7 culverts on the old golf course in an effort to begin restoring the river and that’s where we came in. We helped prep the site for the heavy equipment that will be used in the culvert removal. The areas were brushed as volunteers removed trees, buckthorn, and debris. 


We finished the day with our signature SEWTU Brat Fry. Thanks to all who helped out. Now that a large portion of land adjacent to the stream is public, we anticipate being involved in future restoration efforts as well.
