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.
