Severe drought restrictions (alerte renforcée) in force

The surface-water zone "ITON AMONT" (dépt 27) is at alerte renforcée, the second-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°37903

Temporary notices from official orders and recent fishery reports — they clear automatically once out of date.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

Head to
Wind driftSW wind
North-eastern end

A southwesterly has held for 10 hours, running warmer than the water (21°C air against 15°C water). Expect fish at the north-eastern end — the bank it is blowing into — where the drift piles food, colour and warmth together. This reads the upper water, though — a bottom bait at range feels it far less than a floater or a fish in the margins. Treat it as a tiebreaker between good swims rather than an override — features and angling pressure usually count for more.

How to fish it · for Rainbow
When
Current conditions suit Pisciculture Moulin de la Chaise Dieu du Theil well for autumn tactics. The ripple should help fish move and feed more confidently.
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.
