How to fish it · for brown trout
When
Through the open trout season. Spring olives and grannom; sedges through summer; small dark flies into autumn close.
Where
Pool tails and the seams behind boulders through the Morbihan-Côtes-d'Armor stretches. The Blavet runs Breton freestone water. The Blavet is a longer Morbihan-Côtes-d'Armor system with broader middle reaches.
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

Brittany Atlantic salmon river flowing from Plouay toward the Atlantic. Granitic geology provides rapid drainage and clear water. Spring salmon March–May peak with quick response to Atlantic rainfall. Fish rising phase when fresh water brings fish upstream. Standard Atlantic techniques: larger tubes in flood, dries as conditions drop. Sea trout excellent. Verify Morbihan regulations.
