Flooding + Boone Dam Update

[ newest updates at top ]

WAFB – Plaquemine Ferry service suspended starting Monday

BATON ROUGE, LA (WAFB) – The Louisiana Department of Transportation and Development announced Friday the Plaquemine Ferry service will be suspended starting Monday, Jan. 18 due to high Mississippi River stages.
DOTD will be monitoring the conditions closely over the weekend, and in the event that the river rises to a level that makes it unsafe to operate, the Department will alert the public if closure earlier than Monday, Jan. 18 becomes necessary.
On Jan. 8, DOTD crews built a higher elevation approach that allowed the ferry to remain open an additional week. It will also allow the ferry to reopen roughly one week sooner once the river levels fall.
Based on the current river stage forecast, DOTD expects to resume service by Jan. 28, but that will depend on field conditions.

St. Charles Parish: Mississippi River flooding  < has video

Don’t blame the recent flooding along the Mississippi River on the rain. We created this mess.

flood . . . . Not only are its levees dilapidated, but that stretch of the Mississippi is thick with hardware like wing dikes, which are rock jetties that jut perpendicularly into the river from the banks. Structures like these are designed to help barges navigate by concentrating the river’s flow. But as I wrote in this 2014 cover story for onEarth, wing dikes also make floodwaters more turbulent, slowing them down and raising them higher.

River rises as crest lowers

The Mississippi River is almost 8 feet higher than its 48-foot Greenville flood stage. The National Weather Service anticipates the water to crest at 56.2 feet Wednesday, making it almost 4 feet lower and a day earlier than originally expected.

The New YorkerThe Control of Nature (1987) Atchafalaya

” . . . The Mississippi wants to go west. Nineteen-seventy-three was a forty-year flood. The big one lies out there somewhere—when the structures can’t release all the floodwaters and the levee is going to have to give way. That is when the river’s going to jump its banks and try to break through. . . .”


Meanwhile, at Boone Dam . . . .

SULLIVAN / WASHINGTON CO.,TN (WJHL) In the days immediately after the October 2014 discovery of a structural problem at Boone Dam, internal TVA emails show staff had grave concerns about the dam and the potential impact on the safety of people downstream.

  1. What is a Wing dam or wing dike
    Some researchers believe that flooding is increased by wing dams.
    Many wing dams are often underwater and may be difficult to see.
    https://en.wikipedia.org/wiki/Wing_dam

    Technical Notes
    Theoretical Analysis of Wing Dike Impact on River Flood Stages
    The question of whether wing dikes (bank-perpendicular river training structures or groynes) cause higher flood levels has been debated in the United States for many years.

    • If the structure that keeps the Mississippi from becoming the Atchafalaya fails, it would be one of the largest catastrophes in American history.

      Did the Army Corps of Engineers built to many levees on the lower reaches of the Mississippi River ?

      Just what is Atchafalaya it a name of a river.
      What about it the old Mississippi river coarse could be lost all the water would go down the Atchafalaya river.
      http://www.newyorker.com/magazine/1987/02/23/atchafalaya

      I think Edgar Cayce said something about the Mississippi river changing coarse.

      • I will add that to the post.
        Whole thing is tragic. This time of year the midwest should have had a snow storm, not a rain storm. It would be more manageable because of slow melt… not a rush of water.

    • I sort of think the worse culprit it the little levee building building upstream by all those Kansas farmers etc. to protect fields. Water couldn’t soak in to many square miles because it was steered away.
      I am sure after this they will look at the big picture and see if that is such a good idea.

      • according to that New Yorker article it could!
        Plus it said all new construction, town growth etc. in upper Miss. adds to the run-off waters/flood water. Lots has been built since the last big flood year.

  2. I been looking up all I can find the old history about the army engineer company i was in.
    The Lineage of my old company from WW-2 to Jan. 13, 2003.
    I have found more on my old company in WW-2 it was top secret at that time they were working alongside Union Oil and Standard Oil.

    • Lucky Lake Charles …
      I think all this is for export of LNG to China etc. (as they just improved containers, shipping etc.)

  3. The article Walter found is the only one I found with a good explanation too. However, no one tells if it will just go west north at the Atchafalaya or gradually ease. Waterford is on the West Bank of the Mississippi just facing Bonnet Carre spillway. The spillway could speed erosion at Waterford I finally figured out because it is an outer part of the bend. Look at Hymelia crevasse on google earth. Downtown Baton Rouge on the River used to have a good explanation the size of a wall around 45 years ago. Don’t know if it is still there. We need something good on the Mississippi embayment. Heavy rains going across can furthermstress dams. They should have opened the Morganza to protect the reactors and their access. Riverbend reactor,itself is high enough at 95 ft I think. Waterford can be in trouble. Also Grants Bayou can go to 110 ft near Riverbend. Both MSL I think. I worked on this a lot but no time to post it.

    • That long New Yorker article explained Atchafalaya is 30 feet or so lower than land to the east… so I think that’s why they say west.

      • It also has to do with shortest route to Gulf. They are controlling how much water goes into the Atchafalaya R. If not most of the Miss. would be in the Atchafalaya. However, I don’t know if all would just go at that split which is above two reactors or shift gradually. We need a good topography map.
        The land has ups and downs. Not clear to me how it works in the lower part with the two reactors. The east bank seems to be lower than the west at Waterford but that didn’t stop the Hymelia crevasse which was induced by burrowing crawfish. It was just north on the west.

  4. Also for Hymelia the River drained into the back swamp and rolled back toward Killona. NRC only calculates still water in the event of a breach. They have a concrete box but I am skeptical still about flood safety at Waterford. I think it is a grand Gulf where in combo rain flood they have three inches contingency and talk of sloshing through two feet of water in the buildings

    • New Yorker article graphically described what happens when runaway barges get loose in flood waters and smash into things….

      • Yes, I found some other info on that in public domain sources…Some nearly hit the water intake for Waterford. I have saved all the little pieces and pics but need time.

  5. Boone Dam, flooding of the Mississippi, it is all the same, nothing to worry about our great leaders say. I had no idea a water intake valve for Waterford on the river was subject to being hit by barges.

    • There is that good New Yorker article in the recent post about the flood coming (on the Atchafalaya Basin) and the loose barge was smashing into the control tower … with people inside the building.
