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.

How to fish it · for brown trout
When
Through the open trout season. Iron Blue and CDC grannom in April; olives through May; sedges through summer evenings.
Where
Pool tails and weeded glides through the Pas-de-Calais chalk-stream stretches around Étaples. Intimate water; read each lie.
Method
Upstream dry to spotted rising fish; long fine leader. The water reads clear — careful approach matters more than fly choice. Move slowly upstream, cast accurately, accept the result.
Kit
9 ft #4 — French karst-stream default. Floating line, 14 ft leader to 4 lb fluoro. Polarising glasses non-negotiable.
Why this works
⚠️ Water at 20°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

The Canche is the kind of river where you slow down without meaning to. It rises out of the Artois chalk above Fressin and runs roughly northwest to Étaples, picking up the Course and the Ternoise on the way and gaining in character with every tributary. The water is clear, heavily watercressed, cool in summer — proper chalk stream water that surprises anglers who think of Picardy as flat arable country. Wild brown trout through the middle reaches, grayling in the bigger pools, and sea trout running in from Étaples when the water has colour. Mayfly hatches around Brimeux in May, sedges through the long evenings of June. The beats around Hesdin and Montreuil-sur-Mer are classic — AAPPMA and private estate water mixed together — and the fishing rewards people who'd rather watch for twenty minutes before tying on.
