How to fish it · for brown trout
When
Through the open trout season — 2nd Saturday of March through 3rd Sunday of September. Spring olives April through May; sedges through summer; spate-driven on falling water.
Where
Pool tails, riffle heads, and the seams behind boulders through the Morbihan beats. The Scorff is medium-scale Breton spate freestone.
Method
Upstream dry to risers; dry-dropper through the riffles. Breton spate freestone — fish 12 to 24 hours after rain on the drop. Long leader, fine tippet.
Kit
9 ft #4 — Breton spate freestone. Floating line, 12 ft leader to 4 lb fluoro. Studded boots.
Why this works
Good — water temperature is working for you, but time of day is the limiting factor today.

About this water

Atlantic salmon river on granitic Armorican bedrock in southern Brittany. Spring salmon runs March–May peak. Fish rising water after Atlantic rainfall when fresh flow brings fish upstream. Clear water between spates thanks to granite drainage. Standard tactics: tubes 1–1.5 inch in flood, dries as water drops. Sea trout present. Check Morbihan arrêté for season and regulations.
