Character of the water

Blanktjärnen lies in central Sweden — a nutrient-rich lowland lake. In summer a thermocline settles around 7 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 (18 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing Blanktjärnen

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

The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Blanktjärnen are alike.

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.
