Read the full account →The Big Muddy River rose well above flood stage in response to persistent thunderstorms. A front became stationary across the region from the 17th to the 20th. During this four-day period, rainfall totals ranged from 2 to 8 inches across the Big Muddy River basin.
Read the full account →The Ohio River was above flood stage for virtually the entire month from Grand Chain to the confluence of the Mississippi River at Cairo. Major flooding occurred from Grand Chain to Cairo, where flooding was the worst since the Flood of 1997.
