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.
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.
A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

- Wind conditions (ripple) closely match what this water fishes best in.
- High temperatures may push fish deeper and reduce surface activity.
- Daddy longlegs are in their seasonal window, boosting the chance of targeted feeding.

Alpine char (Saibling) — seasons, minimum sizes, and retention rules are set by the Bern canton's fisheries authority (Amt für Jagd und Fischerei). Different cantons may apply different closed seasons or catch restrictions for char conservation. Always verify locally before targeting char.
- Lake trout 1 March → 31 December
Lake trout (Seeforelle) — seasons and regulations are set by the Bern canton's fisheries authority. Minimum sizes, retention rules, and boat permits vary. Check current regulations with the cantonal office before fishing.
