Head to
Wind driftSW wind
South-western end

A southwesterly has held for 7 hours, running colder than the water (12°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
Conditions are not ideal but fishable at Sources de l'Éclimont.
Where
Start with Diawl Bach (12-14) — on the bob / top dropper — slow figure-of-eight retrieve. 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 Diawl Bach (12-14) — on the bob / top dropper — slow figure-of-eight retrieve. 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.

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 spring-fed fly reservoir at Abbéville-la-Rivière in the Essonne, roughly an hour from Paris, historically run as a private day-ticket fishery alongside the farm's trout production. It is the antidote to the city: clear water fed by its own sources, stocked with rainbow and brown trout. The operator's branding has shifted toward farm produce and open-days, and their site currently states there's no trout fishing on-site — but recent social media activity suggests anglers are still getting on the water at times, so this may be a seasonal or welfare-driven suspension rather than a permanent closure. Confirm current status and booking directly before planning a visit.
