Jackson River Professional Review and Guide
"The middle section above Hidden Valley is wonderful and well worth fishing. Virginia’s Highland and Bath Counties are a compressed terrain. The mountains here have been crumpled upwards by thrusting of a continental plate from the southeast. In the valleys between the mountains run a number of rivers with some fishing—Bullpasture, Cowpasture, and Calfpasture—but the best trout river in this neck of the woods today is the Jackson, a river with good browns in its free-flowing middle reaches. It wasn’t always so. Until the mid-90s the Jackson boasted an outstanding tailwater fishery below Garthwright Dam which impounds Lake Moomaw, ten miles or so north of Covington.
Anyone caught fishing in a King’s Grant section without permission is liable for prosecution. Some landowners post their property, others do not. Written permission is essential. There is some fishing in the mile immediately below the dam, but most fly shops in the region recommend that anglers try their luck farther upstream. Local TU chapters and the state department of game and fish are working hard to resolve this issue. Anglers who receive permission to fish can find themselves hooked onto nice browns in this year-round, easily waded fishery. Species: Brown, rainbow. Angling methods: spin, and fly-fishing."
