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 fishing near inflows, dam walls, and weed beds. Move to find feeding fish.

About this water

A spring-fed fly reservoir at Abbéville-la-Rivière in the Essonne, roughly an hour from Paris and run as a private day-ticket fishery. It is the antidote to the city: clear water fed by its own sources, stocked with rainbow and brown trout, fished on the venue's own terms rather than a federation card. Useful when you want a half-day on still water without driving to the Jura. Book ahead and check whether it's running catch-and-release.
