What a July! Those evening storms have been perfect, keeping our rivers full of cool water and the fish super active. We've had a lot of questions about Sulfurs on the South Holston, and the good news is, we're still seeing those yellow bugs! The hatch has held up beautifully all month, giving us plenty of dry fly chances. While the Sulfurs will likely slow down as we get into August, it's a perfect transition because the terrestrial bite is going off! Trout have been keying in on ants and beetles, making for some exciting dry fly fishing, particularly first thing in the morning.

When it comes to topwater fishing this season, poppers for smallmouth bass are our absolute favorite. The thrill is unmatched—watching a bass stalk a popper and then sip it is pure excitement. These visual, surface eats make for an incredible fly fishing experience and will certainly put a serious bend in your rod!

Check out this sequence of a big smallmouth taking a popper!

Trout fishing on the South Holston has also been fantastic! Afternoon and evening water releases from the dam have made for awesome fishing all throughout July. If you're looking to fish Sulfur dries, we've found the prime time is between 1 p.m. and 3 p.m.

Check out this incredible 23-inch brown trout that was landed this month! The key to success was simply changing midge colors. Small flies work extremely well during the summer months.

Brett traveled all the way from Texas to fly fish the South Holston River, and it certainly treated him well. These three beautiful brown trout were the result of his efforts! Great job, Brett!

August is officially underway, and the great fishing continues! We even enjoyed some temperatures in the low 80s last week, though warmer weather is expected soon.
