About the Committee

The Lake Welfare Committee studies all problems and issues relating to Nagawicka Lake and the Bark River within the city limits.  

If you would like to serve on a Board, Committee, or Commission - please fill out an interest form. Common Council is on the application in case there is a vacancy and the Common Council would need to fill the position prior to the next election.

Adopt A Portion of the River

Adopt-A-River is a volunteer program which encourages local groups, Scout Troops, business and civic organizations, churches, families, etc., to adopt a City of Delafield portion of the Bark River and clean up refuse a minimum of two times per year, once in the spring and again in the fall. The Public Works Department provides the garbage bags, closure ties, and dumpsters for the materials.
