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.
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.
