How to fish it · for rainbow
When
Conditions are not ideal but fishable at Moulin de Boizard. The ripple should help fish move and feed more confidently. Very warm conditions — trout have a narrower safe zone of cool, oxygen-rich water. Fish only at first light or last light, use barbless hooks, keep fish in the water during release, and stop if fish struggle to recover. Early morning is often the most productive window in summer — make the most of it.
Where
Start with Spent Spinner (16-20) on a on a floating line. 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 Spent Spinner (16-20) on a on a floating line. 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

Fish early and late, try deeper during the heat of the day with a fast-sinking line.

Watch for

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Bank

Bank fishing near inflows, dam walls, and weed beds. Move to find feeding fish.

About this water

Boizard is a hybrid fly venue on the edge of the Perche — a 1.5-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.
