Levee updates from the Southeast Arkansas Levee District, Chicot County Judge Mack Ball, National Weather Service, and the Mississippi River Levee Board.
January 20 – As you know, the river crested as expected approximately one week ago. The river stage this morning at Greenville gauge is expected to be just over 54′. The river should continue its fall and hopefully it will be below official flood stage by next week some time.
Today will be the final day for the Corps of Engineers to be monitoring the levee system as part of their emergency operations. They should be wrapping up operations this morning and making their way back home. “Thank You” to the Greenwood Area Office and all of their crew from both Greenwood and Vicksburg! We appreciate all you do to assist us, not only during high water situations, but also in more normal times.
During this time of high water the Corps of Engineers has gathered information about our levee system, especially with regards to the upgrades that have been completed since 2011. It seems that the upgrades (relief wells, additional berms, etc) performed as expected and seemed to have mitigated many of the problems that we saw in previous floods. That being said, each flood event is unique unto itself and we must always be prepared to react to the situation that arises. Corps engineers will now take the information that they have gathered and make further recommendations to refine the system to provide continued protection during future high water events.
A big “Thank You” also goes out to all those groups and individuals that assisted us in our operations during the flood. Your presence and willingness to do what was needed is appreciated! We know that many of you worked long hours and at less than convenient times. Thank You.
As the water recedes, we will be getting back to normal operations. As part of the return to normal, the levee system will open to public travel on Monday, January 25. Please be mindful that even though the waters are receding, wildlife will still be displaced and that can be a hazard to both them and you.

January 10 – Corp of Engineers has reported an updated crest at Greenville. It is to crest at 56.2′ on Wednesday. This is good news. Here are the updated forecasts. A few changes were made along the rivers to lower crests.
Greenville crest was lowered to only stay in moderate flood stage and not reach major flood stage.
Arkansas City, Vicksburg and Natchez will still reach major flood stage.
Crests were lowered as follows:
Arkansas City: -0.8 feet
Greenville: -1.3 feet
Vicksburg: -1.5 feet
Natchez: -1.0 feet
Dates of all the crests along the Mississippi River remain unchanged.
Crests were also lowered along the Black River/Boeuf Rivers in Northeast Louisiana. Acme and Jonesville Lock and Dam will remain only in action stage and not reach flood stage.

January 5 – Southeast Arkansas Levee Board Update: The US Army Corps of Engineers has people on the ground that are assisting in inspecting the levee as the river continues to rise. They have inspected and are continuing to inspect the slides that have occurred before the river began to rise. According to the USACE, the cause of the slides does not have its origins in the rising river. Rather, the slides have been caused over time as the soil has expanded and shrunk in relation to the weather. As you know, this summer was very dry and since the drought broke, the rain has been nearly constant. As the soil loaded up with water weight, the ground shifted at natural shrinkage lines and the slide was created. The slides are a normal occurrence on the levee and each one is evaluated to ensure the the integrity of the levee is not compromised. As of today, no slide that has been identified has compromised the integrity of the levee system. We will continue to monitor the situation and keep you informed if anything significantly changes.
As the river continues to approach its crest, we will be increasing our levee patrols and will begin 24 hour monitoring. We have added additional personnel as needed to assist in the efforts. The Forestry commission and the AGFC are also assisting us. The levee system remains closed to non-essential traffic and will likely remain closed until further notice.
These has been no change to the forecast river crests as of this morning. The forecast can be found at http://www.srh.noaa.gov/lmrfc/…
We appreciate your patience and cooperation in this situation. — Southeast Arkansas Leavee Board
January 4 – Round-the-clock levee patrol begins. The Arkansas Game & Fish, Arkansas Forestry Law Enforcement, Chicot County Sheriff’s office as well as other agencies are enforcing a mandatory ban on levee traffic.
Only citizens who require the levee to access their permanent residence will be allowed to access. All other vehicles will be stopped and issued citations. Please continue to monitor the river stages and we will continue to provide you with updated information as it becomes available. Thank you all for your cooperation.– Chicot County Judge Mack Ball
