Flood Levels
As the river level increases at a gaging station the risk for potent loss of life and property increases. Below are definitions for the different flood stages and the damage that can be expected.

  • Major Flood Stage - Expect extensive inundation of structures and roads. Significant evacuations of people and/or transfer of property to higher elevations becomes necessary.
  • Moderate Flood Stage - Expect some inundation of structures and roads near stream. Some evacuations of people and/or transfer of property to higher elevations becomes necessary.
  • Flood Stage - Expect minimal or no property damage, but possibly some public threat.
  • Action Stage - Flooding becomes a concern. River/stream is approaching or is forecast to approach the gage height - flood stage - where flooding is defined to begin. Flood stage is an established gage height for a given location at which a rise in water surface level begins to create a hazard to lives, property, or commerce.
