  • The Planning and Preparation occurs below the river level shown. It corresponds to an action stage in the City/County Plan.
  • The Ready for Action Phase occurs after the river levee shown is reached and continues as long as the river is high.
  • The Emergency Phase occurs after the river exceeds the level shown. At this point, there is a greater likelihood that a Mandatory Evacuation Order will be issued soon. Prepare to leave the area.
  • To determine which phase is in effect, please listen to a local radio or television station for the reported river levels and then review the above chart.
  • Recommended actions to take in each phase must be considered when preparing for the possibility of flooding. Take action when YOU need to! Only you are responsible for protecting your property and inventory.
