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.

Seasons & zones
  • Salmon 1 March → 30 September
  • Trout 15 March → 30 September

Sea trout: Variable seasonal (2026)

Salmon: Negligible (2026) — EA 2024 Salmon Stocks Assessment classifies the Taw 'at risk' — egg deposition below Conservation Limit. C&R mandatory. The river still produces salmon every season but stocks are well below historical levels; the better story now is the sea trout run, which remains one of the strongest in southern England.
