Character of the water

Mörtträsket lies in the cold north — a northern mesotrophic stratified lake. In summer a thermocline settles around 7 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 (16 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing Mörtträsket

The species list of Mörtträsket runs to 7. The predators — perch, pike and trout — 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 Mörtträsket are alike.

General rules of thumb for this kind of water

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