Details about Lake Guntersville change. Confirm current lake levels, dock rules and listings with TVA and a local agent before you decide.
Are they the same kind of lake?
Yes, in the ways that matter to a boater. Both are main-river TVA lakes with navigation locks, and both are part of the same river system. TVA holds its main-river lakes steadier through the year than its tributary storage lakes.
Watts Bar Lake has more than 39,000 acres of water and 722 miles of shoreline. Its level changes about 5 to 6 feet between summer and winter. For Guntersville, check TVA's lake level page for current numbers. Our guide to Watts Bar Lake levels explains what to ask.
TVA's shoreline rules apply on both lakes. So the dock question is the same in either state. Ask TVA what a permit would allow on the specific lot before you count on a dock. At Tennessee National, ask what is possible on a specific waterfront homesite and what TVA requires.
One difference in reputation: Guntersville is a lake anglers know well. If fishing is the center of your plan, give it real weight.

Around Lake Guntersville, life is more independent. You make your own calendar, and what is close depends on the shore you pick. Plenty of buyers want exactly that. Ask what is near the shore you like, including golf.
What drives the cost at each?
On an open lake, price follows the water, the dock and the house. A local agent can show you how those price out around Guntersville today.
At Tennessee National, the cost question starts with the five ways to own: The Timbers (wooded homesites), lake homesites, waterfront homesites, Land & Home packages and townhomes. Homes are custom built and go through design review. There is no deadline to build after you buy a homesite. Pricing is in the info pack.
The state line matters for taxes too. Tennessee has no state income tax. Alabama's rules are different. A CPA can compare the two for your situation. Our guide to moving to Tennessee from Alabama covers the basics.
