This is just in from my friend Chris Scalley at River 
Through Atlanta says. "It's hopper time!" While many Hooch anglers turn to subsurface nymphs as usual standbys; may we suggest terrestrials as an option for early autumn. Here in the piedmont of Georgia we typically do not recieve our first frost until late October or even early November. Here in the South; land based insects such as grasshoppers, beetles and ants continue to be available to Chattahoochee trout through December. Our clients are startled to see trout attempting to inhale their strike indicators. This is a sign that big dry flies are on the menu!
The River Through Atlanta guide team was able to fly fish/prospect the Cumberland river in Jamestown, Kentucky on September 9th and 10th. Water temps were 59F releasing from Wolf Creek dam and water temps at Winfreys Ferry warmed to 66F but then cooled back down to 59F after a pulse release from the sluice gate. The biggest trout caught was a 19inch brown on a woolly-bugger and a 18inch bow on a hopper. Despite the warmer then usual water tempertures the fish remain healthy and we hope this trophy trout fishery will remain in tact.
River Through Atlanta is conducting professionally guided fishing trips year round on the 48 mile stretch of the Chattahoochee river that runs through the Chattahoochee National Park. Why not join them for a full or half day wade or float trip. More about boating the Hooch.
