Character of the water

Tretjärnarna lies in central Sweden — a humic brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. In summer a thermocline settles around 8 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 (12 m) — shallow bays, the odd reef and a deeper channel through the middle.

  • Pike: keep at most one over 75 cm per day.

Fishing Tretjärnarna

perch, pike and burbot sit at the top of the food chain in Tretjärnarna, carried by roach, bream and ruffe. The brown, humic water keeps visibility short — the fishing is more about vibration than sight.

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 Tretjärnarna are alike.

General rules of thumb for this kind of water

  • Brown, humic water dampens the light — fishing can be good even in the middle of the day.
  • Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
  • Nutrient-rich lakes hold plenty of baitfish but often murky water.
