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.

Permits & rules

Fishing permit required — Kotjärnen FVOF. Day permit ~100 kr · annual permit ~500 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 Kotjärnen

perch, pike and zander 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.

Every session at Kotjärnen is fished in whatever conditions hold right then — the same pressure, wind and light as over the real water. What bites today isn't what bit the day before, and those who return learn the water for real.

General rules of thumb for this kind of water

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