A three wieght is perfect, a 4wt is great, and a 5wt works.
My advice for the first timer:
1. Start at the red gate. Look for a red gate with a small pull in on the right at the beginning of the park. If you hit the creek crossing you went to far. Walk down the hill on the truck path and go straight into the trees. The creek will be in about 20 yards. Fish upstream until you hit the waterfall hole...turn around and fish back down stream.
2. For a little bit of a longer day. Park at the pull in at the creek crossing (on the right). Fish the hole on the otherside of the road, and then fish upstream until you hit the waterfall hole. Again, turn around and fish back.
3. Fish drys and nymphs upstream, and strip/swing woolies, cracklebacks and wets going down. My favorites are 16 Elk hair, 20 Griffins Gnat, 16 pheasant tail, 18 scud, 20 zebra midge, and 16 wet hare.
4. Long leaders and 6x or 7x tippet
5. Nothing larger then 16s on nymphs and drys...this is a general rule, but if the bite is on try a large dry with a dropper especially in the riffles.
6. Wear earth tone clothes.
7. Don't pass up a hole of any depth with cover or broken water near by.
8. If you spook a hole, give up and move on. Hit it on the way back.
9. Watch the shadow that you and your rod make.
10. Try not to ripple the water.
11. Sling shot cast into really tight holes (keep your fingers behind the hook point). There is a lot of cover...side arm, flip, and role casts to the name of the game.
12. Expectations....Go with the mindset that it a hike in a great Ozark stream and fishing is a bonus. Fishing can be easy, but most time it is a lot of exercise.
13. Finally, every fish in this stream is precious...get them in, quick pic, revive, back in the water.
14. NORMALLY, the water is to small for competing fisherman. If there is a car in the pull off, keep going down stream until you have clean water.
