With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. In the calm, a single dry fly or a slowly-fished nymph tends to out-fish an active retrieve.
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.
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Flat calm suits bank fishing near features — points, weed beds, and inflows where fish patrol.

A good match for Lac d'Alfeld — most conditions are close to what it fishes best in.
1st-category lake near Sewen at the foot of Ballon d'Alsace. Car-accessible alpine lake with fario trout and char. Strict fly-only management protects wild populations. Cold, clear water. Accessible alpine lake fishing with good potential. Spring through early autumn. Check Haut-Rhin regulations.
WFD code removed 2026-06-18: this alpine lake was incorrectly sharing the Doller river's code FRCR53. EEA WISE has no dedicated lake (LW) water body for Lac d'Alfeld, so status is left Unknown. Source: discodata.eea.europa.eu. | Prior note: WFD ecological status Moderate → Good corrected to EEA WISE 2022 (3rd RBMP) classification for waterbody FRCR53 (was a stale earlier-cycle value).

French lake char (omble chevalier / omble de fontaine) — seasons and retention rules are set by departmental regulations and local fishing associations (AAPPMA). French char lakes are often managed with strict rules. Check the local AAPPMA or departmental fishing regulations before targeting char.
