Yeah, Tom ... unfortunately they're making their way up the Tenn River, and may be showing up in Chickamauga & Watts Bar before long. When they do get into Watts Bar, that will take that lake off my list of lakes to fish.
They've gone as far as they can in KY & Barkley lakes, so they're not a menace to any lakes North of there (in KY) ... but, they have traveled up the Salt River, as far as they can go, which is the spillway below Taylorsville Lake. They can't get into the lake, because there is no lock for them to get thru ... so as long as nobody nets them as "Shad" and takes them up to the lake, then the lake is safe from them. Of course, it wasn't safe from the Zebra Mussel, so who knows.
