Severe drought restrictions (crise) in force

VigiEau lists this venue's surface-water zone (bassins de la Doller amont, de la Fecht, de la Weiss et de la Lauch, dépt 68) at crise, under an official préfectoral drought arrêté. Fishing is not itself banned by it, but water levels are low — go gently on stressed fish.

How to fish it · for Trout
When
May–September
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.
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.

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.

Bank

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