Character of the water

Trollsjön lies in the cold north — a northern mesotrophic stratified lake. In summer a thermocline settles around 13 m and splits the lake into two worlds.

The surroundings

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

A small but surprisingly deep pocket (30 m) with steep drops straight down from shore — the bottom falls away fast.

Zander: minimum size 45 cm · protected during the spawn (Apr–May).

Fishing Trollsjön

The species list of Trollsjön runs to 6. 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 Trollsjön 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

Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
