Kit
9 ft #4 rod, floating line, 12 ft tapered leader to 4–5 lb fluoro tippet.
Why this works
⛔ Water at 22.2°C. This is the line where catch-and-release kills brown trout. Do not fish for them today.

About this water

Lower Silesian tributary flowing near Wrocław, brown trout and grayling in mixed mountain-to-lowland transition water. The Wrocław permit material explicitly shows Bystrzyca under trout-and-grayling management, making it a rare city-proximate river with genuine fly-fishing pedigree rather than stocked convenience water.

What this classification means

WFD re-coded 2026-06-18: prior id PLRW20001823456 was a fabricated stub (no such code in EEA WISE). Re-mapped to PLRW60000313455 'Bystrzyca od Zb Lubachow do Zb Mietkow' — the Bystrzyca Dolnośląska (Świdnicka) between the Lubachów and Mietków reservoirs, at the venue coordinate (50.845, 16.49, Świdnica). NB this is NOT the Bystrzyca Dusznicka (a separate Kłodzko-area river). Status: EEA WISE 2022 (3rd RBMP). Confidence: medium-high (coordinate-matched). 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.
The dawn and dusk windows score higher than the midday lull.
