Head to
Wind driftSW wind
South-western end

A southwesterly has held for 9 hours, running colder than the water (8°C air against 14°C water). The end it blows into is taking that chilled surface water, so try the sheltered south-western end instead — off the back of the wind, where the undertow returns food along the bottom. That chill sits in the top of the water, though, and the bed is slower to feel it — on a bottom bait it is the undertow, not the temperature, that puts you at this end. Treat it as a tiebreaker between good swims rather than an override — features and angling pressure usually count for more.

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. Early in the day, try buzzers on a slow figure-of-eight or a booby on a fast-sink line near the bottom. 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. Early in the day, try buzzers on a slow figure-of-eight or a booby on a fast-sink line near the bottom. Rainbows respond to more active retrieves — try short strips between pauses.

Plan B

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

Watch for

Buzzer may strengthen through the middle of the day as conditions warm.

Bank

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

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.
