Update from Peter Nimrod 5/16/11
Update from Peter Nimrod of the MS Levee Board:
Good News!
The MS River is cresting at Arkansas City!
UPDATE – May 16, 2011
CURRENT GAGE READINGS
Arkansas City 53.1’
Greenville 64.2’
Vicksburg 56.5’
MS RIVER FORECAST
They lowered the Greenville crest by 6” to 64.5’ on May 17th:
Arkansas City 53.1’ cresting
Greenville 64.5’ crest on May 17th
Vicksburg 57.5’ crest on May 19th
This forecast will exceed the 1973 highwater levels by 6’.
This forecast will put us 3.5’ above the 100-year flood on the MS River.
The 100-year flood on the MS River is 61’ at Greenville and 54’ at Vicksburg.
YBW AREA FORECAST
The Steele Bayou Structure is currently holding out 16’ of water from inundating the MS Delta!
Unfortunately the Yazoo Backwater Levee is designed to overtop during a major highwater event. Calculations determined that the YBW Levee would overtop at 56.3’ on the Vicksburg Gage. Today we were at 56.3’ and we still have ~1’ of freeboard. It appears that this overtopping number is a little on the conservation side! At this point it looks like we will only overtop by less than a foot – maybe even less! The poly sheeting is in place on the landside slope of the Yazoo Backwater Levee to protect the levee when it is overtopped. We expect that the YBW Levee will withstand this overtopping event at the current stage forecast
SAND BOILS
Seepwater is a natural phenomenon during a highwater event. Sand Boils occur when seepwater travels fast enough to carry material. If these carry material – it could be creating a cavity or hole. We treat sandboils with sandbags to prevent these from moving material. The Levee Board has responded to numerous sand boils and has corrected each one. This will go on for the next month until the river drops significantly.
There will many sandboils during this historic flood event – please don’t be alarmed were you hear that we have a sandboil on our levee system.
MANY THANKS!
The Levee Board has been assisted the Corps, contractors, county officials, inmates and by numerous volunteers during this highwater event. Contractors have been called at the most inconvenient times and they have stepped up and delivered! Volunteers have showed up at the door asking to help. By the way - if you have any problems near Lake Washington – this community will bring an army to help! Inmates have been called in to handle the tough physical work. County officials have loaned us equipment, operators and materials. People have brought food to the weary staff and crew of the Levee Board. Our Levee Board Commissioners have stepped in to handle media, attend meetings, bringing supplies, carrying sandbags, providing support and even running some equipment! Our small Levee Board staff and crew has split up to handle multiple seepage issues at the same time. Our office girls and attorney have handled all the “crazy” phone calls with eloquence and grace. All of you have contributed to the success of passing this historic 2011 Flood. The Levee Board is very humbled by your support, thoughtfulness and helping hands. Be reminded that when the MS River crests we will still be expecting and fighting underseepage issues for the next month. The Levee Board will not rest until this River drops down ~15’.
RELAX AND ENJOY BEING A PART OF HISTORY
We are fast approaching the historic crest of the 2011 Flood and our Levee Inspectors are busy monitoring the levee. They are doing a great job for us! Our crew is working overtime to make sure our levee system is going to successfully pass this historic flood. The Corps of Engineers is busy assisting us on technical issues. I am very proud of our crew, staff, volunteers, partners and citizens.
The Levee is performing as designed.

Relax and enjoy being a part of history.

No kidding. He must be tone deaf.
Re: yazoo backwatet levee status ?
I'm sure he was just trying to calm some folks worried about sand boils.

Re: yazoo backwatet levee status ?
As of this morning, Per Paul Hollis - Sharkey Co Levee Board Commisioner - it had not.
No updates since then but I think we'd have heard locally if it was. Will know more in the morning.

I heard it was still not overtopped this morning. Good news for the people in the Yazoo BW area.
