Character of the water

Koltjärnen lies in central Sweden — a 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.

A small but surprisingly deep pocket (15 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

Fishing permit required — Koltjärnen FVOF. Day permit ~140 kr · annual permit ~700 kr.

  • Pike: keep at most one over 75 cm per day.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Koltjärnen

The species list of Koltjärnen runs to 5. The predators — perch and pike — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

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 Koltjärnen are alike.

General rules of thumb for this kind of water

  • In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
  • Nutrient-rich lakes hold plenty of baitfish but often murky water.
