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 south-westerly putting a ripple across the surface, it does a passable impression of somewhere wilder than it is. Day and season permits via the association.
Buzzer on Lac de Gravelle
Good wave on — drift country. Drift fishing weather — three flies on a long leader.
The buzzer is on. Fry may also come into play as the day warms. The ripple is helpful — fish should move onto the feed and a slow-drifted team or single wet will cover water well.

How to fish it · for brown trout
When
The buzzer is on. Fry may also come into play as the day warms. The ripple is helpful — fish should move onto the feed and a slow-drifted team or single wet will cover water well.
Where
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. In the ripple, a bushy searching dry (Hopper, Shipman's, Elk Hair Caddis) outperforms flush emergers — it stays visible and holds the surface tension.

The plan
Plan A
Set up a broadside drift and cover the water systematically. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. In the ripple, a bushy searching dry (Hopper, Shipman's, Elk Hair Caddis) outperforms flush emergers — it stays visible and holds the surface tension.
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
Buzzer may strengthen through the middle of the day as conditions warm.
Boat — drift
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.
