There were quite a few great floods in Nth America and you'd have needed more than a raft to ride them out. There was the Lake Bonneville "flood that geologists estimate to have lasted up to a year. It is estimated that this breach [of the natural dam] released 1,000 cubic miles (4,200 km3) of water in the first few weeks."
Further north were the Missoula Floods, first recognised in the 1920 by Bretz. It's now believed that there were 40+ floods over a 2000 year period at the end of the last glacial as ice dams formed and ruptured. Estimates of the peak flow rate of the largest flood range from 17 cubic kilometers per hour up to 60 cubic kilometers per hour
. The maximum flow speed approached 36 meters/second (130 km/h or 80 mph).
