Major Flood Stage (Dangerous Water Level)	★Water level for evacuation of residents have been completed
Moderate Flood Stage (Special Warning Water Level)	◆Water level is one of the criteria for giving a directive for evacuation. *Depending on the rainfall circumstances, it is quite possible that the water level will exceed the dangerous flood level, and you will be required to evacuate in such a situation.
Minor Flood Stage (Warning Water Level)	▲The water level for the water brigade to commence their activities
Action Stage (Notification Level)	●Water level for the water brigade to start preparation for their activities.
