Character of the water

Mörttjärnen lies in the cold north — a northern clear oligotrophic deep lake. The water is crystal-clear and the fish skittish in the sharp light. In summer a thermocline settles around 10 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 (21 m) with steep drops straight down from shore — the bottom falls away fast.

  • Pike: keep at most one over 75 cm per day.
  • Trout & Arctic char: protected during the autumn spawn · catch-and-release on certain stretches.

Fishing Mörttjärnen

perch, pike and Arctic char sit at the top of the food chain in Mörttjärnen, carried by roach and vendace. The clearer water makes the fish wary — and rewards a careful presentation.

Every session at Mörttjärnen is fished in whatever conditions hold right then — the same pressure, wind and light as over the real water. What bites today isn't what bit the day before, and those who return learn the water for real.

General rules of thumb for this kind of water

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
  • In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
