All sorts of flat bridges and creeks to try out. Me personally, unless I was trying to catch a hybrid on a flyrod, I would skip the Barren tailwaters.
For trout Trammel in allen co has both browns and rainbows. Any other creeks have smallmouth and spotted bass.
If Barren is on your way, Peter Creek Unit of the Barren River WMA is a nice wadeable area that has nice smallmouth. Park in the small gravel lot and walk past the gate onto the WMA and fish from where the road crossing is back upstream. You can wade a good ways up through there but there is one deep hole that you need to get on the bank for.
