The upper South Fork of the Holston River in the Mount Rogers National Recreation Area is a major tributary of the entire Tennessee Valley Drainage. For its first 30 to 35 miles, the South Fork is a high-quality trout stream. To this end, the U.S. Forest Service designated slightly more than two miles of the best portion of this stream as “Artificial Single Hook Lures Only” and established a daily creel limit of two fish of 16 inches or longer. To encourage compliance with this new regulation, the Forest Service, with help from Wildlife Forever, erected a large interpretive sign telling people about wild trout, how to observe them, and the value of catch-and-release fishing.
