How to fish it · for Rainbow
When
Conditions are not ideal but fishable at Sources de l'Éclimont. The ripple should help fish move and feed more confidently.
Where
Start with Small Damsel (8-12) — 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 Small Damsel (8-12) — 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

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.

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.
