Severe drought restrictions (crise) in force

The ITON AMONT zone (Dept 27) is at crise — the second-highest French drought tier — under a préfectoral arrêté. Fishing itself is not named as prohibited, but water is severely restricted and flows are likely very low; fish with care and check locally.

Arrêté préfectoral n°37605

Temporary notices from official orders and recent fishery reports — they clear automatically once out of date.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 Moulin de la Chaise Dieu du Theil. 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 Chironome (12-16) — on the bob / top dropper. Midday in warm weather — switch to a fast-sink or Di-7 and fish boobies or blobs along the bottom. Rainbows respond to more active retrieves — try short strips between pauses.
The plan
Plan A

Start with Chironome (12-16) — on the bob / top dropper. Midday in warm weather — switch to a fast-sink or Di-7 and fish boobies or blobs along the bottom. Rainbows respond to more active retrieves — try short strips between pauses.

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-only venue. Fish from accessible margins, points, weed edges, and inflows.
