Head to
Wind driftN wind
Northern end

A northerly has held for 11 hours, running colder than the water (3°C air against 12°C water). The end it blows into is taking that chilled surface water, so try the sheltered northern end instead — off the back of the wind, where the undertow returns food along the bottom. That chill sits in the top of the water, though, and the bed is slower to feel it — on a bottom bait it is the undertow, not the temperature, that puts you at this end. Treat it as a tiebreaker between good swims rather than an override — features and angling pressure usually count for more.

How to fish it · for Rainbow
When
Current conditions suit Moulin de Boizard well for winter tactics. The ripple should help fish move and feed more confidently.
Where
Start with Klinkhåmer (12–14) on a As per local method. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A

Start with Klinkhåmer (12–14) on a As per local method. Rainbows respond to more active retrieves — try short strips between pauses. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

Slow down everything. A booby on a fast-sinking line, left static, can pick up deep fish.

Watch for

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Bank

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

Ranked for today
Rainbow fly box

Classic French chalkstream fishing. Gin-clear, weed-rich, slow to moderate flow. Dry fly and sight nymphing dominate. Stronger sedge hatches than English equivalents. French tradition favours flush-sitting dries (comparaduns, CDC patterns) and upstream presentation.

About this water

5-hectare spring-fed reservoir plus around 2.8 kilometres of small river flowing through the grounds of an old mill. It is roughly ninety minutes from Paris, which makes it the go-to weekend venue for a decent number of Île-de-France fly anglers who want something more interesting than a pure stillwater ticket. The river section gives you actual stream fishing on the chalk-edge water of the Perche country — modest fish, but genuinely wild-looking conditions in the right light — and the reservoir stocks rainbows to keep the numbers honest. The combination works. You can fish the river early, move to the reservoir in the middle of the day when the river is quiet, and go back to the river for the evening rise. This is not Normandy chalk stream fishing in the full English sense, but it is a serious day on the fly within driving range of Paris, which counts for a lot.
