The closing of the Opryland Hotel is a bad thing for the 3,000+ people who work there. They have been promised at least six weeks pay, but it may be six months before the hotel reopens. Kudos to the hotel management for their decision to evacuate guests and employees despite assurances from officials that the levee system around the hotel was sufficient to prevent any flooding.
For the record, the Cumberland River which flows through Nashville is a tributary of the Ohio (not the Tennessee) River. Dams and locks on the Cumberland are under control of the US Army Corps of Engineers...not the TVA. I think they did the best possible job saving the dams while releasing the least possible amount of water from the reservoirs. What they could not do...what I suspect no one can do...is predict what will happen when you get 16 inches of rain. There are too many small creeks which flow unabated into the Cumberland. While it was the Cumberland that ravaged downtown Nashville and Opryland, most of the residential flooding came from these small creeks which are considered picturesque in normal weather.
In Nashville, we are taking care of our own...no looting, no screaming for the Federal government to do something for us immediately, just neighbors helping neighbors. This is the Volunteer State after all. We lost 31 people statewide in the flooding and the damage estimate in Nashville alone is $1.5 billion and that's private property only...none of the public buildings.
