Achensee

View across Achensee lake toward the snow-capped Karwendel mountains near Pertisau, Austria

Tyrol's largest lake, deep and cold and crystal-clear—the sort of stillwater that demands either a boat or knowledge of the right bank positions.

How to fish it · for Trout
When
No strong hatch signals at the moment — general searching tactics should work best. Calm evenings on lakes can be magical — watch for rises and fish individual fish with dries.
Where
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.
The plan
Plan A

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.

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

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Either bank or boat

Calm evenings can fish well from bank or boat — target rising fish wherever you find them.
