Remarks

 

Flooding from the Lake George Breakout is not known to have occurred until it wiped out three Indian villages on the Knik River just before 1900, although people living in the region said it emptied itself every 15 to 20 years before that. Irregular flooding from the Breakout occurred until 1914. Thereafter until 1966, during almost every June or July, Lake George floodwaters threatened structures on the Knik River flood plain.
Since 1966, the gorge has remained open and therefore Lake George has not formed. There seems to be no question about whether or not the Lake George Breakout will again occur; it is just a question of when.
