Flooding Information
New Berlin Floodplains
The City of New Berlin has floodplain areas mapped along the following creeks, rivers, and tributaries:
  • Calhoun Creek
  • Deer Creek
  • Poplar Creek
  • Root River
  • Tess Corners Creek
  • Underwood Creek
  • Upper Kelly Lake Tributary

We are at the headwaters of these watersheds; therefore, we do not experience the same flooding as, for example, the Fox River. Flash-flooding is the general type of flooding associated with our waterways. In June of 2008, storms caused flooding all over the region. The city experienced temporary road closures on 124th Street due to the Root River over-topping the road in several locations. Poplar Creek caused flooding at Calhoun Road and Victor Road, and the Kelly Lake Tributary backed up to Grange Avenue and the subdivisions to the north. In all, there were 80 road closures throughout the city. The majority of flooding that occurred in the city during the storms was associated with local drainage systems and the shear volume of water experienced over a short time span.
