Character of the water

Trehörningen lies in central Sweden — a acidified forest lake. The water is crystal-clear and the fish skittish in the sharp light. Acidification has thinned life down to the hardiest few.

The surroundings

The lake sits close to town with a road right up to it — easy to reach, but hard-fished and exposed to nutrient runoff from the buildings and fields all around.

Moderately deep (7 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Trehörningen FVOF. Day permit ~100 kr · annual permit ~500 kr.

  • Pike: keep at most one over 75 cm per day.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Species in Trehörningen

perch predatory fish
typically ~22 cm · can reach 45 cm
Perch moves carefully in the clear water — small mouthfuls, many of them.
pike predatory fish
typically ~62 cm · can reach 120 cm
In the clear water pike picks its moments — wary, but relentless once committed.

Fishing Trehörningen

Trehörningen holds 2 species, with perch and pike at the top of the chain. The modest depth keeps most of the fishing within reach of the bank.

Whoever fishes Trehörningen regularly builds something of their own: a log of what took, where and when. That's how the water gives up its patterns — cast by cast, never all at once.

General rules of thumb for this kind of water

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
  • Acidified water yields few, hardy species.
