Drainage districts are local governmental entities organized primarily to drain lands for agricultural use but may include other purposes. The majority of drainage districts in Wisconsin were formed in the early 1900s and established a legal mechanism for managing drains and related facilities to ensure reliable drainage. Drainage districts can include and benefit both agricultural and non-agricultural lands. Property owners whose land benefits from being in a drainage district pay assessments to cover the cost of constructing, maintaining, and repairing district drains. More information:
