After a careful study of the land, this is what I came up with (for those of you who don't know what the fuss is about). Correct me if I'm wrong on this.
1.The Sunflower River splits in DNF. The Big Sunflower flows easterly and the Little Sunflower flows south.
2.The mouth of the Big Sunflower used to be at Lake George, near Holly Bluff, near where Silver Creek and Panther Creek emptied into Lake George.
3.Lake George is a cutoff of the Yazoo River.
4.A channel was cut about mid-way down lake George to connect the Big Sunflower with the Little Sunflower. The Big Sunflower flows through Lake George.
5.The Whittington Channel cut lake George in half, and empties into the Yazoo where the Big Sunflower used to empty into the Yazoo (the mouth of Lake George). The Whittington Channel takes pressure off of the Yazoo about 11 river miles south of Belzoni. Yazoo overflow that used to drain through Silver Creek down to Holly Bluff (into Lake George), and through several lakes into Panther Creek (into Lake George) now flows through this straight channel with levees on both sides.
6.The Whittington channel levees prevent the Big Sunflower from exiting Lake George at the original mouth.
7.The Big Sunflower now meets the Little Sunflower in the south end of DNF and they empty into the Yazoo a few miles south of the Lake George mouth at the original mouth of the Little Sunflower. (The mouth of the Big Sunflower was just moved a few miles south of its original mouth)
8.There is a flood gate at this point where the combined Little and Big Sunflower rivers enter the Yazoo. A new channel (with a levee) was also dug at this point and parallels the Yazoo River along the hill line. This will allow the gate to be shut and the Sunflower River won't dump into the Yazoo here, but will flow through the new channel southward.
9.This new “Sunflower River” channel enters Steele Bayou at the Yazoo River just north of Vicksburg and there is another flood gate here.
10.Steele Bayou drains the western Delta from Yazoo Refuge and also takes the runoff from Deer Creek (which drains the western Delta from Greenville area).
11.The Yazoo then empties into the Mississippi a couple of miles further south. When the MS River rises, the gates are closed to prevent the MS from backing up into the Sunflower and Steele Bayou. But it can still back up into the Yazoo, which is sandwiched between the natural hill line and the man-made levee that separates the Sunflower from the Yazoo. When the gates are closed, however, the Sunflower River and Steele Bayou back up into the surrounding land with no way to escape. A pump would dump all of this water (pretty much everything from Coahoma County southward that doesn’t drain through the Coldwater, Tallahatchie and Yazoo Rivers) into the MS River and would prevent the pooling of water in most of the South Delta.
12.In essence, the straightening and dredging of the Yazoo, Tallahatchie, Coldwater and all of the channels dug everywhere in between, quickly removes water from the entire Delta. This means that when the gates on Steele Bayou and the Sunflower River are closed, all of the water from Tunica county south speedily makes its way to the south Delta where it sits. Levees in place on most streams to the north prevent floodwater from fanning out across the land, so they quickly move southward and put exponential pressure on the south Delta.
On one hand I sympathize with the south Delta folks, who get flooded with Delta water more quickly now than before all of the dredging, channelization and levees were put in place. They get all of our north and central delta water (and that from the hills that drain through the Big 4 Reservoirs) more quickly now than the way God designed it. To sum it up, a canal dug in Tunica county to get the water off of a farm field more quickly, in effect, quickly puts more water on the south Delta. A levee on the Tallahatchie River to keep the land along the banks from flooding means a higher, faster wall of water making its way down a straightened river to the south Delta. To do all of the other projects and not install the pump is like spending 75 years restoring a classic car only to not put a water pump on the motor.
But on the other hand, when the MS River is high enough to force the closing of the flood gates, the south Delta doesn't flood nearly as much as it would if the gates were not in place and the MS River would quickly spread out across the south delta. So they still get wet, but not wet from the MS River directly. In a perfect "delta" world, the MS River would rise, the gates would be shut and there would not be a bunch of water from rain in MS causing the Delta rivers to swell. Then the MS River would go down and the gates would open again and the Delta rivers would flow again. But when you get a rising MS River and a rain-soaked Delta, the problems are magnified.
The way it is right now, a pump to suck out the water from the Sunflower and Steele Bayou would complete the process that was begun when the dredging, channeling and levee system was begun so many years ago. A process that I sometimes wish was never begun, but because of it, the Delta is an inhabitable place and not a malaria-infested swamp. I guess the only way to "undo" it all would be to knock down the levees, let the straightened rivers go back to their crooked paths through the hundreds of oxbows and cutoffs that now lie dormant, and let the canal ditches fill up with silt.
Either way, the natural south Delta that flooded at the whim of the MS River and all of the Yazoo basin tributaries or the new south Delta that lies protected behind a wall of levees and flood gates, it still gets wet. A flood is a flood and the animals, trees, people and land are going to suffer regardless. It's called a "flood plain" for a reason. If you choose to live in it (as I do), be prepared to face reality and accept the consequences of nature's natural process. If my house floods tomorrow because a levee breaks or we get 8 inches of rain overnight, I'm not going to find anyone to blame other than myself. (I read the article in the paper today about Vicksburg residents upset with the police because they hadn't come by to bring them snacks and check on them like they did back in 1973). If I wanted to guarantee myself I wouldn't get wet, I'd move to Arizona.
A vicious cycle, no doubt.
