The real problem is that the Corp of Engineers and probably every state government official of significance knew or should have known the consequences of allowing all possible water flow through the dam floodgates and thus the levees or building restrictions which should have resulted.
I assume that the Corps built the dams with discharge capability related to historic precipitation records and river flow data and that they assumed that such large discharges would at some time be necessary. To ignore those facts for 50 years seems to me to demonstrate a level of arrogant incompetence of some kind. Or perhaps, as a poster at Mt. Blogmore suggested:
A man-made disaster sponsored by the usual suspects: hubris, greed, self-interest, and the willful-blindness that – this time is different and it won’t happen here.
There are other implications. It is hard not to wonder if this man-made flood mess which we had 50 years to prepare for..not just days as Gov. Daugaard keeps saying and Sen. Thune suggests could be prevented or ameliorated if we would just all pray to God, may also say much about the potential for climate catastrophe. The above "usual suspects" and fossil fuel industry propaganda all chime in ways which ring with the dull thud of something like "What Me Worry?".
Even if the plausible idea that activity by man generating carbon dioxide and other pollutants causing serious significant climate change is not correct, we have much to gain anyway by inventing new energy systems to produce and reduce consumption of fossil fuels.
This appears to be mostly win-win with little danger versus the potential for planetary catastrophe. What is wrong with our political leaders and elite? Are they all so tied to rich contributors and special interests that they really don't give a damn about the future of the earth or the future of their children and their children? Or for that matter if they just ignorantly and stupidly build on flood planes because they assume some expert or the government is protecting them.
