Norfork..... For the "best" chance hire a guide.

The Norfork has a fairly high concentration of Brookies and Cuts. Cuts are usually in the center sections of the river this time of year. For 12 inch brookies you are best to fish at the dam in the deep portion along the river left bank right below the dam. Although you can catch brookies and cuts literally anywhere on that river so it can happen any time. This is specifically because you want all of them over 12 inches.
