Bayou Corne/Grand Bayou Response Activity

Monday, Aug. 26 work-

Sinkhole Activity Code 3 – highest alert level, no work allowed on sinkhole or within containment berms – though no elevated levels of seismic activity have been detected since last week’s event, Code 3 set today due to sinking of trees this morning near area of last week’s sloughing of sinkhole along eastern edge – at present, today’s sinking is believed to be related to last week’s shift, but the situation is being monitored closely for potential further development.
