The flooding problem

  

Over the last 50 years, flood flows on the Rock River have risen substantially. The reach of the Rock River between Hustisford and Ixonia is particularly sensitive to this increased flooding due to its shallow slope and large floodplain area. The increased flooding in this reach of the Rock River has negatively affected agricultural land, woodlands, wetlands, and recreational use. These flooding impacts include:

  • More frequent floods and higher flood levels, which intensify flood‑prevention challenges
  • Longer flood durations that inundate agricultural land, woodlands, wetlands,     and recreational areas
