Character of the water

Kalvsjön lies in the south — a southern clear oligotrophic deep lake. The water is crystal-clear and the fish skittish in the sharp light.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

Large and deep (21 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

Permits & rules

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

Kalvsjön holds 7 species, with perch, pike and zander at the top of the chain and bream, ruffe and roach schooling beneath them. The depth gives the water two storeys — and the fish move between them with the season.

Every session at Kalvsjön 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

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
  • In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
