Hi Todd!
I'm RIGHT on the Mississippi here, 395.7 river miles above the confluence of the Ohio river, and I'm 3 statute miles from USACE Lock and Dam #14. Here's a hydrograph of the last 7 days' waterflow:

Now, that waterflow curve looks pretty viscious, but in reality, it's not- at anything under 40,000 cubic feet per second, the river is essentially standing still. Here's what the hydrograph looked like in the flood of 2001...

Here's a view of the yard at 15.27' and 225,000cuft/sec

When that upper (solid blue line) goes above the 13.5' mark on the left, the water is above my front seawall, about a foot deep in the UPHILL side of the boathouse (about 2.5' at the lower end). When it crosses the 15.5' mark, water is across the road in front of my house, and lapping the driveway apron. At 27.5', water laps up against my front-porch foundation, the East Moline Case-IH plant is submerged to it's roof, Silvis, East Moline, Moline, Bettendorf, Rock Island, and Davenport are all without water and sewer services. Needless to say, in the 110 years that it has been here, the foundation of my house has NEVER been touched by the by the river... stage has never exceeded 19.7' right here. I am, however, 9' below the 100-year flood plain according to FEMA's Flood Insurance Rate Map... that puts the 500-year floodline at about the peak of the I-80 bridge...
But today, We're fine here....
