Any fishing tips for Toccoa river in late summer?

Haven’t fished for trout there much but stop by the local bait and tackle shop, folks are usually helpful
In Arkansas and NC, red worms or power bait in similar shape to a small worm on a drop shot with 6-8 pound test works well. Also, mepps spinners can do the trick

Love that area, but have always been there in April/May timeframe. I'm a pretty novice fly fisherman with a few attempts on vacations in different locations every year, but always managed to catch some trout around there. Stop into Cohutta Fishing Co in Blue Ridge and they will point you in the right direction.

Trout are lazy. They face upstream into the current on the slower side of a seam between faster current and wait for bait to float by close to them. The trout will dart across the seam grab the bait, and back into the slower current all in two short movements. They also sit behind big boulders in the eddies or anywhere slower water is with faster turbulent water moving very close. They could be in a cut bank of deeper water with faster water moving above them. They just want the food coming close by to their mouths so they can do a quick grab and go back to their relatively calmer water spot.

So fish walking upstream against the current and cast upstream (at maybe 45% angles or what makes sense) near seams, eddies, pockets and cut banks and let your bait float back downstream, knowing that the trout are facing the faster water waiting on your bait to float by. Don't cast into the middle of the fast water. Cast near the edge of the fast water.

Use baits that mimic what they eat. If you fly fish, then dry (floating) flies or sinking nymphs are great. If you are spin fishing cast a rooster tail or small bait with a metal spinner, or live worm or powerbait.

Ask a local bait shop what they recommend.
