It may or may not be of interest to some...
I am not trying to compare other disasters, the folks in Joplin had very little warning of the nightmare that occurred there. The folks in Fargo go through this every year...It happened on the Mississippi earlier.
Bismarck to my knowledge has not seen this since 1952, the year before the Garrison Dam was finished.
This water level is at 80,000 cfs coming out of the dam, 150,000 cfs is a shocking number to me.
