Character of the water

Trolltjärnen lies in the cold north — a northern clear oligotrophic forest lake. The water is crystal-clear and the fish skittish in the sharp light. In summer a thermocline settles around 5 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.

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

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

Fishing Trolltjärnen

Trolltjärnen holds 3 species, with perch and pike at the top of the chain and roach schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

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 Trolltjärnen are alike.

General rules of thumb for this kind of water

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
