Re: Current River
Ozarkanglers.com is definitely worth a look. Also, missouritrouthunter.com has a good description of the trout sections of the Current. That would help you pinpoint where to start looking for smallies.
I understand there's an aluminim hatch on that river. You might want to time your visit to avoid it. I've not seen it myself, but it might be something to investigate as you plan your trip.
Tie up your crayfish patterns!
