Character of the water

Isojärvi lies in the cold north — a northern mesotrophic stratified lake. 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 (13 m) with steep drops straight down from shore — the bottom falls away fast.

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

Fishing Isojärvi

The species list of Isojärvi runs to 12. 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 Isojärvi are alike.

General rules of thumb for this kind of water

  • Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
