Slow going — pick your moments
River temperature is the limiting factor today, not the flow. Fish dawn or dusk if you go at all, and handle everything with extra care.

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.

  • Mixed
Water quality (WFD)
  • Ecology: Poor
  • Chemical: Failing to achieve good
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.
A drop and clear would lift the flow and clarity scores.
The dawn and dusk windows score higher than the midday lull.
