sorry for the late reply.
I wouldn't mind sharing the exact location, but I didn't mark any waypoints. We just run up the creek until it gets too shallow, and float back down, stopping to fish any holes where we get bites, or running back upstream to re-float a good spot. Henrietta hole is always the big producer & usually has people fishing the bank there.
Otherwise, bends where there's a cut bank on one side and sand bar on the other are generally promising. You'll see quite a few spots like that. Faster moving current is better. Most of the fish are caught in mid-channel.
We didn't fish below the 377 bridge, but I bet there will be some there. I pretty much run full out up to 377 (it's not more than 30mph in my old boat), then back her down a bit from there. There's plenty of water though.
