Levee, trees sink after week of tremors at sinkhole ~The Advocate, River Parishes Bureau~BAYOU CORNE — A 400- to 500-foot section of the containment levee around the Assumption Parish sinkhole has gone under water after almost a week-long active period of tremors, parish officials said Tuesday. 
Parish officials said in a blog post that the levee sunk as part of a broader subsidence along the southern side the sinkhole. Trees along the southwest side of the sinkhole are also showing signs of sinking, in some cases as much at 10 feet down, parish officials said.
