Just saw a news story on this. Apparently it is a done deal. The Corps said it was complying with a federal regulation that had not been enforced previously. If that is the case, this may be coming to TVA dams as well. The Corps will be putting up barriers in the form of buoys strung on cables from the photos in the story. The news story showed photos of the now restricted areas, but I cannot find them elsewhere. The Nashville district office web page has not had a word about this other than posts opposing it. Appartently they just post the warm fuzzy stuff.
