Character of the water

Trehörnan lies in the south — a southern nutrient-rich lowland lake. In summer a thermocline settles around 5 m and splits the lake into two worlds.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

Moderately deep (12 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Trehörnan FVOF. Day permit ~140 kr · annual permit ~700 kr.

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

Fishing Trehörnan

The species list of Trehörnan runs to 4. The predators — perch and pike — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Trehörnan are alike.

General rules of thumb for this kind of water

  • Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
  • Nutrient-rich lakes hold plenty of baitfish but often murky water.
