How to fish it · for Rainbow
When
March–November
Where
Start with Booby (10-12) — on the point. 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 Booby (10-12) — on the point. 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

A fry-imitating pattern stripped through the margins can save a blank in autumn.

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.

French réservoir fishing with strong competition influence: chironomes, Diawl Bachs, blobs, boobies and active lure work all matter.

About this water

A small family-run put-and-take fishery in the Juine valley, working the pond system around a mill that has stood since the 18th century. Straightforward stocked rainbow trout across four ponds, sold by the half or full day with no catch limit — a relaxed few hours by the water rather than a technical session. Tackle can be hired on site. Treat as provisional until current operating status is confirmed by phone.
