Flood, maximum probable

What is Flood, maximum probable?

Flood, maximum probable meaning The highest value of the stage or discharge attained by a flood; thus, peak stage or peak discharge. Flood crest has nearly the same meaning, but since it connotes the top of the flood waveit is properly used only in referring to stage–thus, crest stage, but not crest discharge.
