Nedre Fättjarn

Character of the water

Nedre Fättjarn lies in the cold north — a northern acidified brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. In summer a thermocline settles around 9 m and splits the lake into two worlds. Acidification has thinned life down to the hardiest few.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

Large and deep (48 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

Fishing Nedre Fättjarn

Nedre Fättjarn holds 1 species, with perch at the top of the chain. The depth gives the water two storeys — and the fish move between them with the season.

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 Nedre Fättjarn 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.
• In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
• Acidified water yields few, hardy species.
