A flood of this magnitude would be rare; the combinationof forces necessary for occurrence would be extremely infrequent.A flood of this magnitude, however, could happen at anytime. A flood larger than the Standard Project Flood is also possible,but the combination of factors necessary to produce such aflood would be extremely rare.20
