let's take a closer look at this issue. you see the mississippi here coming down through tennessee, arkansas, down mississippi and into louisiana. here's essentially what this looks like. morganza spillway looks like this. here's how it is on a normal day, a little bit of water comicome ing through. the gates stop the water. if you decide to open the gates, you can see how that works. you let a lot more water through the gates. that's pretty basic how it would work. the question is, what are the consequences? let's bring this down. i just showed you an animation of one gate. there are 125 of them. 125 bays across the spillway. it stretches 4,000 feet. it controls access, 4.5 million gallons of water. i want to show you why this is so important, as this plays out. here's the sense here, you see this flood area here? look at the scale here. if it's pink, it's moderate flooding. if it's orange or red, it's severe flooding. this is a scenario right now, if they open the spillway about halfway, this is the scenario. now, obviously, you see some flooding here along the edge, but you see new orleans and this area in here more populated, much less flooding.
