If you ever get to fish the Cumberland River below Wolf Creek Dam, you will need a lot more than that. It's essentially the only bait used by most successful fishermen. Generally fished as a dropper behind a larger fly. Cumberland is the site of the state trout hatchery and a huge river stocks directly. With a water temperature of 52 year round, it also has a lot of naturally spawning trout that are stocked to add breeding stock.
The new artificial trout stream is something unique.

I was built over several years with intense planning, is over a mile long, and includes almost every type of trout habitat normally found in eastern fisheries. It includes a lot of habitat catering to spawning and young trout, and is protected by structure to reject marauding fish from the river (including large stripers which prey on the trout in the river).
I fished it when just 6 months or so after opening, and it is an incredible little stream to fish. Biologists report that the spawning effort has been a big success.
It will never replace the miles of drift boats on the main river, but it is a wonderful personal fishing experience.
