- 600 feet
Mississippi River would be flooding the banks in Kentucky at 300 feet.
At 400 feet, Owensboro would be inundated from the Ohio River. At the
600 foot mark, most of the land east of Bowling Green will be underwater
except a peninsula from Russellville to Hopkinsville stopping right before
Princeton. Marion would be a small island. The Ohio River would also create
a few rivers flowing south into Kentucky. One of these would inundate
Louisville and flow south as far as Hodgenville. Not much above 600 feet,
a newly formed tributary of the Ohio River coming from the northern border
will inundate the state capital of Frankfort.
