How to fish it · for Rainbow
When
The buzzer is on. Fry may also come into play as the day warms. Strong wind will make open-water drifting difficult. Look for sheltered bays and lee shores.
Where
Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
The plan
Plan A

Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.

Plan B

If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.

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.

Conditions are away from Lac de Gravelle's sweet spot — it usually fishes best in ripple wind with cloud skies.

About this water

A one-hectare lake tucked into the southern Bois de Vincennes and set aside specifically for fly fishing — a proper Paris oddity. Managed by the APBV (Association de Pêcheurs au Lancer et à la Mouche du Bois de Vincennes) as a no-kill fly-only fishery: barbless or de-barbed hooks, trout returned, landing nets required. Stocked with rainbow trout and a smaller proportion of browns. Twenty minutes from a Métro stop, which is the point: on a damp Tuesday in April with a southwesterly putting a ripple across the surface, it does a passable impression of somewhere wilder than it is. Day and season permits via the association.
