The lakes in this area are governed by Tennessee Valley Authority (TVA). A number of things are taken into consideration when building on the water, several of which require a permit. Flood lines cannot be crossed, even for building structures like swimming pools, without prior approval. Docks, and whether or not they can be built, are also regulated by TVA. Some properties are dockable but some are not. Often the size of the dock and location of the property in regards to the lake navigational channel will be contributing factors. In some areas TVA also controls whether or not trees can be removed from the property. Many factors come into play so you need an agent experienced and knowledgeable about everything lakefront!
