South Mills River – wild
Remote wild browns and rainbows on National Forest water. The nearby Mills River gage is a neighbor’s weather report — not this exact reach.

Insects by season
Southeast seasonal guess, tuned a bit for this water type. Stage tips from the insect notes. Cross-check water lists against NCWRC / VA DWR.
- Winter (Jan–Mar)Midges; BWO; Early Black Stones; Blue Quill; Quill Gordon late Mar.
- Spring (Apr–May)Hendrickson, March Brown, Quill Gordon; Grannom → Hydropsyche (pupa key); Sulphurs evening; Light Cahill; Giant Stones; BWO.
- Early summer (Jun)Sulphurs, Light Cahill, Yellow Sally, Green Sedge, first terrestrials.
- High summer (Jul–Aug)Terrestrials; Yellow Sally / Golden Stones; Tricos on slower water if present. Ethics critical.
- Fall (Sep–Dec)Terrestrials taper; Light Cahill dusk; midges + BWO; Early Black Stones; October Caddis. Brown spawn — avoid redds.
Gap: No South Mills-specific hatch list. Do not conflate with North Mills DH.
Temp & time of day
Thermometer on the reach. Proxy 03446000 can hint trend only. Remote hike-in: do not encourage a long walk into water already in the mid–upper 60s.
Access
Remote wild-trout National Forest water. Stay on public NF / signed access. Confirm NCWRC Wild Trout regs (typically artificial-only — confirm). Low-pressure ethic: do not treat as a high-pin DH destination.
Conservative one-liner only. No parking spots, crossings, or trespass workarounds.
Use the linked USGS pages and a thermometer on the water. Where a Grade A bind is live, the card above pulls current readings.
