Caddisflies
The Wild & Scenic border river between Georgia and South Carolina — cold, tumbling headwater forks holding native specks, opening into wild rainbow and brown water downstream. Rugged, beautiful, and almost entirely public.

How to fish it · for Brook Trout
When
Nymphing can work through most of the day.
Where
Cover mixed depths.
Method
Start with tight-line nymphs and adjust if fish rise or drift higher.
Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.
Why this works
Water at 23°C. This is the line where catch-and-release kills brook trout. Do not fish for them today.

About this water
Conservation note
Native brookies in the cold upper forks; wild rainbow/brown lower. brook_trout (char comfort-overlay), rainbow_trout and brown_trout all score post-seed; native brookies handled conservation-first.

What this classification means
EPA ATTAINS assessment unit 'Chattooga River' (GAR030601020222), 2024 Integrated Report. Aquatic Life use: Not Supporting. Listed impairment causes: Metals Other Than Mercury, Mercury. This is a Clean Water Act assessment-unit classification (the US analogue of WFD), not a live reading.
Status is for the Clean Water Act assessment unit covering this reach.
