Who do you contact when you see poor practices?


The area of your property that is within 75 feet of Rock Lake is very important to the water quality of Rock Lake. Please know that there are rules governing what can and cannot be done in this special area. Before you do anything within 75 feet of Rock Lake (including but not limited to cutting of any vegetation, grading of the land, or the construction of buildings, walkways, stairs, walls, etc.) contact the appropriate entity to talk to them about your proposed project. If you live in the City of Lake Mills, contact the building inspector at 920-648-2344. If you live in the Town of Lake Mills, contact BOTH the Jefferson County Zoning Department at 920-674-7130 and the Town of Lake Mills at 920-648-5867.”
