Character of the water

Kalvsjön lies in the south — a southern mesotrophic 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 (17 m) with steep drops straight down from shore — the bottom falls away fast.

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

The species list of Kalvsjön runs to 10. The predators — perch, pike and zander — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

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

In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
