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; small dark flies into autumn.
Where
Pool tails and weeded glides through the Eure chalk-stream stretches. The Andelle is intimate Seine-tributary water.
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
Good conditions. Clarity is favourable (95), Prey activity is weakest (39).

About this water

The Andelle emerges from Normandy chalk moving with the precision of water that knows exactly where it came from. Classic chalk-stream character — clear, stable temperature, rich fly life. Wild brown trout and grayling. Selective fishing required: small, precise presentations to individual rising fish during mayfly, olive, and sedge hatches (April–June). Some beats private; check access before visiting.
