Character of the water

Kroktjärnen lies in the cold north — a northern acidified forest lake. In summer a thermocline settles around 8 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.

A small but surprisingly deep pocket (15 m) with steep drops straight down from shore — the bottom falls away fast.

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

Fishing Kroktjärnen

The species list of Kroktjärnen runs to 13. The predators — perch, pike and grayling — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

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 Kroktjärnen are alike.

General rules of thumb for this kind of water

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