Character of the water

Körsmyrsjön lies in central Sweden — a humic brown tarn. The tea-stained, humic water hides the bottom within an arm's length.

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 — Körsmyrsjön FVOF. Day permit ~140 kr · annual permit ~700 kr.

  • Pike: keep at most one over 75 cm per day.
  • Trout & Arctic char: protected during the autumn spawn · catch-and-release on certain stretches.
  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Körsmyrsjön

perch, pike and grayling sit at the top of the food chain in Körsmyrsjön, carried by ål, elritsa and whitefish. The brown, humic water keeps visibility short — the fishing is more about vibration than sight.

Every session at Körsmyrsjön 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

  • Brown, humic water dampens the light — fishing can be good even in the middle of the day.
  • Nutrient-rich lakes hold plenty of baitfish but often murky water.
