How to fish it · for Rainbow
When
March–October
Where
Start with Black Buzzer (12–16) on a slow, natural presentation — check locally for the preferred method. Evening can produce explosive surface takes — try a foam beetle or booby on a long leader. Rainbows respond to more active retrieves — try short strips between pauses.
The plan
Plan A

Start with Black Buzzer (12–16) on a slow, natural presentation — check locally for the preferred method. Evening can produce explosive surface takes — try a foam beetle or booby on a long leader. Rainbows respond to more active retrieves — try short strips between pauses.

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-only venue. Fish from accessible margins, points, weed edges, and inflows.

Rainbow fly box

Closer to wild-lake trout fishing than to competition réservoirs. More room for naturals, caddis, buzzer, terrestrial and modest lure use.

About this water

A no-kill fly reservoir at Chessy in the Marne-la-Vallée eastern suburbs, listed by the AAPPMA Le Pêcheur de Marne-la-Vallée, with related casting and fly-tying activity centred around Torcy. Not glamorous — and that's why it earns its place. The local club water: practical, slightly utilitarian, and entirely fishable from RER A. Stocked trout, fly-only management, the kind of venue that lets a Paris-based angler get a half-day in without writing off the weekend.
