Kolningsjön

Character of the water

Kolningsjön lies in central Sweden — a nutrient-rich lowland lake. In summer a thermocline settles around 10 m and splits the lake into two worlds.

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 (19 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

Fishing permit required — Kolningsjön FVOF. Day permit ~60 kr · annual permit ~300 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 Kolningsjön

The species list of Kolningsjön runs to 5. 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.

Whoever fishes Kolningsjön regularly builds something of their own: a log of what took, where and when. That's how the water gives up its patterns — cast by cast, never all at once.

General rules of thumb for this kind of water

• Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
• Nutrient-rich lakes hold plenty of baitfish but often murky water.
