Severe drought restrictions (crise) in force

The surface-water zone "Affluents de l’Agout moyen de la Raviège à la confluence avec le Thoré en excluant la Durenque" (dépt 81) is at crise, the highest French drought tier, under a préfectoral arrêté. Fishing itself is not named in the restriction, but flows are low enough for the state to restrict water use — expect thin, warm water and check locally before travelling.

Arrêté préfectoral n°37876 ↗

Temporary notices from official orders and recent fishery reports — they clear automatically once out of date. Always confirm locally before travelling.

How to fish it · for Rainbow
When
Conditions are not ideal but fishable at Pisciculture de Jaladieu. The ripple should help fish move and feed more confidently. Very warm conditions — trout have a narrower safe zone of cool, oxygen-rich water. Fish only at first light or last light, use barbless hooks, keep fish in the water during release, and stop if fish struggle to recover.
Where
Start with Booby (10-12) — 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 Booby (10-12) — 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

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.
