Mörttjärnen

Character of the water

Mörttjärnen lies in the cold north — a northern nutrient-rich lowland 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 (15 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

Fishing permit required — Mörttjärnen FVOF. Day permit ~140 kr · annual permit ~700 kr.

• Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Mörttjärnen

perch, pike and zander sit at the top of the food chain in Mörttjärnen, carried by roach and bream. The nutrient-rich water means plenty of baitfish — and predators that grow fat on them.

Whoever fishes Mörttjärnen regularly builds something of their own: a log of what took, where and when. That's how the water gives up its patterns — cast by cast, never all at once.

General rules of thumb for this kind of water

• Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
• Nutrient-rich lakes hold plenty of baitfish but often murky water.
