Character of the water

Tretuvetjärnen lies in central Sweden — a nutrient-rich lowland lake. In summer a thermocline settles around 6 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.

Moderately deep (9 m) — shallow bays, the odd reef and a deeper channel through the middle.

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

Fishing Tretuvetjärnen

perch, pike and zander sit at the top of the food chain in Tretuvetjärnen, carried by roach, bream and ruffe. The nutrient-rich water means plenty of baitfish — and predators that grow fat on them.

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 Tretuvetjärnen 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.
