Re: Nashville info
As you can tell, Middle Tennessee is not lacking in places to boat. There are few places with two really major lakes within the city limits. I grew up in Nashville, and know all these lakes very well.
I'll stick with Percy Priest as the easiest place to get to, as I-40 East is within sight of the dam. It's a very wide, open lake and there are a number of islands to picnic from.
There are good facilities--including large marinas with restaurants, places to camp and parks with sand beaches. Forget all the other Tennesssee cities' attractions, as Nashville has them all beat for things to do.
Old Hickory Lake is about 10 miles north of Percy Priest, and it's much more residential. I once stopped in the middle of the lake close to Hendersonville, only to find the water about waist deep. It is a lake you need to know where you're going, as you can easily damage your boat. Old Hickory is navigable, however, and you can always stay in the marked channel following buoys for tugboats. Old Hickory also is serviced by good marinas and parks.
The Cumberland River is below Old Hickory, and it's just a 1/4 mile wide river--always cold water and generally boring to be in.
Center Hill is also on I-40 about one hour east. It's a very pretty lake, and very popular with houseboats and fishermen. Unfortunately, it's land locked and those yachtsmen cannot go anywhere in their 85' barges. It's a good place to go, however I suspect water levels are down dramatically since the dam is being rebuilt.
Dale Hollow is 1 hour northwest of Center Hill (2 hrs. from Nashville), and it's a magnificent secluded lake. It'd be a great place to rent a houseboat for a week.
I live on Wilson Lake, Alabama--a 15 mile long lake between Pickwick and Wheeler Lakes. We've got 140,000 people in two counties with the river in middle. Don't tell anyone about this place, as it's a secret. #1 in big smallmouth in the U.S and #1 in big catfish--and the largemouth aren't too bad. Joe Wheeler State Park Resort is close by and three Robert Trent Jones golf courses within sight of our house. This is a great deep water lake that's mostly rock bottom. I cannot believe that Franklin (TN) residents have not discovered this place to buy 10,000 square foot second homes on, as we're just 1 1/2 hrs. away. The Tennessee River is the #1 cruising lake in the U.S. for yachts and houseboats. This is where I've chosen to retire.
