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.
The dawn and dusk windows score higher than the midday lull.
Directions
Seasons & zones
- Sea trout 1 January → 30 September
Polish 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.
- Trout 1 April → 30 September
- Grayling 1 June → 28 February
Polish PZW national rule: grayling (lipień) protected 1 March – 31 May. Open window 1 June – 28 February. PZW district and water-specific rules may add tighter restrictions. Carpathian rivers (San, Dunajec, Biała, Skawa, Raba) hold excellent grayling — check local Okręg PZW district permit for specific conditions.
Closed in spring for spawning.
Prime sport 1 September → 30 November
