Character of the water

Kroktjärnarna lies in central Sweden — a mesotrophic stratified lake. In summer a thermocline settles around 7 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 (17 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 Kroktjärnarna

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

Every session at Kroktjärnarna 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.
