bassboat, I have aksed some local guys for the same info in the state park area, when I get a response I will share it with you. One guy told me they are biting pretty good around the hwy 69 bridge which is only a couple of miles down river from the state park.
If you leave the state park and take a left downriver, go under the hwy 431 bridge and turn left you will see the hwy 69 bridge.
