Character of the water

Kotjärnen lies in central Sweden — a humic brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. In summer a thermocline settles around 8 m and splits the lake into two worlds.

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

Permits & rules

Fishing permit required — Kotjärnen 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.

Fishing Kotjärnen

Kotjärnen holds 3 species, with perch and pike at the top of the chain and roach schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

Whoever fishes Kotjärnen 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.
