Holston River, South Fork Professional Review and Guide
"The Holston River has three forks—North, Middle, and South—but I’ve chosen to concentrate on the South Fork of the Holston because it is the best-known Virginia trout water of the three. The North and the Middle forks both boast good populations of smallmouth bass, but access to these forks is limited because most of the river is surrounded by private land. By contrast, the South Fork of the Holston is much colder than her sisters because it’s fed primarily by huge limestone springs flowing from nearby Sugar Grove. And it has very good cover, which also helps to keep the water cool all year, even in the heat of summer.
Although it’s true that great trout fishing exists on the South Fork of the Holston in Tennessee as well, that will have to wait for another book. Types of Fish: This fishery is known for good rainbows as well as healthy brown trout, some of which can be quite large. You can also catch smallies. This fly-fishing chapter describes the "where, when, and how" for fishing in this area. It includes a full-page map and information on the known hatches, suggested equipment to use, the best flies to use, season, limits, nearby accommodations, and camping."
