Character of the water

Fyrkanttjärnen 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 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.

A small but surprisingly deep pocket (12 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing Fyrkanttjärnen

perch, pike and trout sit at the top of the food chain in Fyrkanttjärnen, carried by roach and vendace. The clearer water makes the fish wary — and rewards a careful presentation.

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 Fyrkanttjärnen are alike.

General rules of thumb for this kind of water

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