Lower Mississippi water flows and inundation map – 11 & 16 May 2011, from the Corps.
Warning to the residents from the Corps’ WWW site:
Every year, written notices are issued to all interests reminding them of the possibility of operation of the floodway. In the event that Morganza needs to be opened, the USACE project managers, along with news media and civil officials, will help notify all interested parties as soon as possible. On receipt of such notice, expeditious action must be taken as soon as possible to protect life and property. If the Morganza Floodway is operated, there is a possibility that personal property will be flooded. In the event of an opening, all water and/or gas wells must be sealed and capped to prevent contamination from floodwaters.
