How to fish it · for Brown 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 18.5°C — above the brown trout caution line (18°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots.
Likely species
Mayflies
Mayflies- Blue-winged oliveMost likely#16–18 · DunDuns are up; a sherry spinner fall may follow.
- Large dark oliveAlso possible#14–16 · EmergerDead-drift the emerger — it's sitting in the film.
- Green drakeAlso possible#8–10 · SpinnerSpinners on the water now — the big fish move for these.
- Iron blue mayflyAlso possible#16–18 · DunCold, grey day — the dun sits long. Good dry-fly water.
Caddisflies
Caddisflies- GrannomMost likely#14–16 · PupaPupa first, then dries as the adults come off.
- Satin sedgeAlso possible#12–14 · Egg-layingSkitter it at dusk — this one's fished, not dead-drifted.

What would change the calculation
Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.
The dawn and dusk windows score higher than the midday lull.
