Many rivers across the region are swollen due to the spring snow melt and persistent rainfall. Thus, many rivers risen to bankfull and many are well above flood stage. People living near rivers that typically experience flooding each spring should maintain awareness of river levels this week.

You can watch river levels and get river stage forecasts for southeast and south central Wisconsin on our local Advanced Hydrologic Prediction Service web page.
