The headwater springs of the New
Small gravel springs above 3,000 feet, discharging into what is widely held to be the oldest river in the eastern US.
The New River's South Fork rises in cold gravel springs between Boone and Blowing Rock, all 46 to 49 degrees. The flow is stable year-round because the springs are fed by deep fractured-ridge aquifers rather than surface runoff. The water is low in dissolved minerals, slightly acidic, and clear to the bottom. The trout fishery is supported by these headwater discharges; below 2,800 feet the river warms and the trout thin out.

The spring creeks of the Black Mountains
Cold spring creeks on the eastern flank of the Black Mountains.
On the slopes below Mt. Mitchell, the forest floor gives up cold water by gravity at roughly 45 degrees through most of the year. The largest spring creeks, Setrock and Cattail, hold native brook trout above 3,500 feet and a wild rainbow population below. The springs discharge from fissures in the migmatitic bedrock and are remarkably stable — diurnal swing across a summer week is less than two degrees. This stability is what makes them trout water.

Flat Springs — the boggy head of the Watauga
A sphagnum-and-spring seep on Sugar Mountain that feeds the Watauga above its reservoir.
Not a single seep but a boggy discharge zone, about three acres, where water emerges through sphagnum and horsetail at 44 degrees. Diffuse rather than point-source, and chemically unusual: slightly tannic, low in calcium, with iron content that gives the bog its rust-orange color. The flow feeds Elk Creek, which is impounded to form Watauga Lake. The spring itself is on National Forest land, reached by a one-mile trail from the Flat Springs access road.
