South Holston River Hatch Chart
Like all hatch charts, this chart is only a general reference. It is not uncommon to find blue winged olives coming off on a rainy July afternoon or sulphurs on a warmer February afternoon.
There are other food sources including but not limited to sculpins, crayfish, aquatic worms, leeches, sowbugs and scuds. The midges and scuds are daily food sources for many of the South Holston trout, so don't leave home without them.
Your fly boxes should include all stages of the insects that might come off during your trip. If you plan to float the South Holston on high water, be sure to include some attractor patterns as well.
