Is the fishing worth the 2 hour drive. Ive only been fly fishing for about 6 or 7 months now. Will I have a decent chance at catching a few trout

You can usually get a decent idea by checking here. http://www.swt-wc.usace.army.mil/ops_hydropower/TENKhydro.html

Thanks Andy, is the any way of checking before I drive out there, I'm thinking about going Monday

Depends on if they got the dam running full blast or not. If it's not running full blast then you have a great chance at landing fish
