High Groundwater and Flooding

Over the past several years, Wisconsin has received a record-breaking amount of precipitation. Climate change has affected rainfall events by increasing the likelihood that they will occur with much more intensity and frequency. The accumulation of above-average precipitation has resulted in many areas of Wisconsin experiencing high water and flooding issues. Information is available from the DNR to help residents cope with flooding.
