The Stage (or Gage Height) at which a general state of readiness must be maintained by concerned river interests in the event of further rises above Flood Stage (similar to a Watch). In some cases, initial action must be taken by concerned interests, such as livestock and equipment removal from the lowest overflow areas. This level may produce overbank flows sufficient to cause minor flooding of low-lying areas and local roads.
