Character of the water
Kotjärnen lies in central Sweden — a humic brown tarn. The tea-stained, humic water hides the bottom within an arm's length.
The surroundings
The lake lies half-remote, a fair way from the nearest road, tucked into woodland.
Moderately deep (5 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Kotjärnen
Kotjärnen holds 4 species, with perch and pike at the top of the chain and roach and ruffe 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 Kotjärnen 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.
