A wild brookie stream falling off Spruce Knob, the roof of West Virginia — high, cold and acidic, with small native specks in step-pool water under spruce and rhododendron. A walk-in fish-high-and-light kind of day.

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 18.6°C — above the brook trout caution line (16°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots.
