How to fish it · for brown trout
When
Through the open trout season. Spring olives April through May; sedges through summer; small dark flies into late September.
Where
Normandy character — pool tails, weeded glides, the cushion behind alder roots. The Sélune flows through small intimate water.
Method
Upstream dry to spotted rising fish; long leader, fine tippet. Move slowly, cast accurately. The Sélune is small water and rewards careful approach.
Kit
9 ft #4 — Normandy default. Floating line, 14 ft leader to 4 lb fluoro. Polarising glasses non-negotiable.
Why this works
Good — water clarity is working for you, but time of day is the limiting factor today.

About this water

The Sélune is the most important river restoration project in European history. In 2021 and 2022, the Vezins and La Roche-qui-Boit dams were removed — the largest dam demolition ever undertaken on the continent — and roughly 90 kilometres of salmon habitat that had been locked away for over a century was opened again to the Atlantic. The scientific monitoring is ongoing and will continue for decades, but the early results are remarkable. Smolts emigrated from reaches that had not seen a salmon in 100 years within months of the reservoirs being drained. Adult fish followed. The fishing is still finding its shape. The lower and middle river below the old dam sites are gradually rewilding — the bed is readjusting, gravel bars are forming, the thermal regime is stabilising — and the salmon are returning in counts that build year by year. Fish the Sélune in the spring window with floating line and long leader for the lower beats, small tubes in coloured water. The upper beats above Ducey are increasingly productive for wild brown trout on a river that is still, in a real sense, being born. Treat the place with the respect the restoration deserves: catch-and-release on every salmon, disinfect your gear, and remember that every fish you meet is proof that a river can come back.

What would change the calculation
Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.
