Water temperature for brown trout
Warm — slow19°C est.ideal 10–16°C
0°14°28°
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 19°C — above the brown trout caution line (18°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots. Otherwise poor — water clarity is in the right range.

About this water
Water quality (WFD)
- Ecology: Moderate
- Chemical: Failing to achieve good
What this classification means
WFD re-coded 2026-06-18: prior id PLRW20001247456 was a fabricated stub (no such code in EEA WISE). Re-mapped to PLRW20001147639 'Leba od Debnicy do Pogorzelicy' — the middle reach (through Lębork) nearest the venue coordinate (54.67234, 17.42156). Status: EEA WISE 2022 (3rd RBMP). Confidence: low-medium — VERIFY the fished stretch against a map; the Łeba has four reaches between Dębnica and Lake Łebsko. Source: EEA WISE SWB_SurfaceWaterBody (discodata.eea.europa.eu).

What would change the calculation
Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.

- Sea troutPolish PZW rules list sea trout/troć closed in remaining rivers from 1 October to 31 December. Local river and district rules may add method/day restrictions, so this should be a default pending river-specific PZW checks.
