Start with this because it looks official [and those water level numbers are sobering]:

Most Interesting. Russian reporting. Pakistani reporting. Claiming Obama administration orchestrated a news blackout effort about flooding nukes. If so, this Google indicates any such total blackout effort was less than fully effective.
_______________UPDATE______________
New item today, local Omaha paper, "What if the dam breaks?" There is this Don't Worry Be Happy dimension:
Both utilities concluded their protections were adequate.
NPPD and OPPD declined to comment Thursday on the NRC's request.
David Lochbaum, director of nuclear safety for the Union of Concerned Scientists, said the good news is that the corps' analyses are recent, so the NRC will have much more current information to act upon. Lochbaum is among the people Congress turns to with questions about nuclear reactor safety.
Since the terrorist attacks of Sept. 11, 2001, the nation's dam breach analyses are no longer available to the public.
“Prior to 9/11 we probably would have released this, yes,” said John Remus of the corps. “Dam breach scenarios involve extremely high flows — much higher than we're experiencing now. ... We're not in fear of losing our dams, so this is not information that we need to share.”
