How to fish it · for Rainbow
When
Conditions are not ideal but fishable at Pisciculture du Moulin Piat. Flat calm means fish may be spookier — longer leaders and subtler flies will help. 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.
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.
