Character of the water

Söderbysjön lies in central Sweden — a humic brown tarn. The tea-stained, humic water hides the bottom within an arm's length. In summer a thermocline settles around 5 m and splits the lake into two worlds.

The surroundings

The lake lies remote, ringed by forest and bog far from any road. Few find their way here — the water is untouched and the stock undisturbed.

Moderately deep (6 m) — shallow bays, the odd reef and a deeper channel through the middle.

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

Fishing Söderbysjön

perch, pike and trout sit at the top of the food chain in Söderbysjön, carried by björkna, 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 Söderbysjön 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.
