The first thing to know is the generation schedule. Here's a link to TVA's website: http://www.tva.com/river/lakeinfo/index.htm
(Even though Caney Fork is a Corps dam, the info is available thru TVA.) Right now Center Hill is running water 24/7 or close to it. You can't wade when water is up. Best we can hope for is a window of time to get in on low water. If recent history holds, it'll be this way for next couple of months.
