Character of the water

Kotjärnen lies in the cold north — a northern nutrient-rich lowland lake.

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.

Shallow throughout (max 3 m), with reeds and vegetation over large areas — water that warms fast in spring.

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

perch and pike sit at the top of the food chain in Kotjärnen, carried by roach and bream. The nutrient-rich water means plenty of baitfish — and predators that grow fat on them.

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 Kotjärnen are alike.

General rules of thumb for this kind of water

  • Nutrient-rich lakes hold plenty of baitfish but often murky water.
