Character of the water

Tretjärnarna lies in the cold north — a northern humic brown forest lake. The tea-stained, humic water hides the bottom within an arm's length.

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

Permits & rules

Fishing permit required — Tretjärnarna FVOF. Day permit ~60 kr · annual permit ~300 kr.

  • Zander: minimum size 45 cm · protected during the spawn (Apr–May).
  • Pike: keep at most one over 75 cm per day.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Tretjärnarna

Tretjärnarna holds 5 species, with perch, pike and zander at the top of the chain and roach and ruffe schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

Whoever fishes Tretjärnarna 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

  • Brown, humic water dampens the light — fishing can be good even in the middle of the day.
