Several systems referred to as "Locks and Dams",

What kind of damage if Locks go? Waterwise? Are there lots of areas with Locks? They would be connected with 'shipping', and there have been threads about tankers being targeted, and one hit near Sri Lanka?? by suicide boats. Just thinking out loud....

Might be some initial flooding downstream,, believe the last set of locks (going Southward) is just below St. Louis. While messing with the lock and dam system would be a major inconvience to farmers and grain handlers, who typically ship grain down river to the Louisiana Ports at this time of year, I certainly don't see any 'National Threat' to messing with the locks and dams.
