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 7 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.

A small but surprisingly deep pocket (13 m) with steep drops straight down from shore — the bottom falls away fast.

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.

Pike hunts by feel more than sight in the stained water — short, hard strikes close to the bait.
roach coarse fish
typically ~18 cm · can reach 32 cm
The nutrient-rich water keeps roach moving constantly between the feeding grounds.
ruffe perch family
typically ~12 cm · can reach 22 cm

Fishing Kotjärnen

perch and pike sit at the top of the food chain in Kotjärnen, carried by roach and ruffe. The brown, humic water keeps visibility short — the fishing is more about vibration than sight.

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.
