Character of the water

Mårsomjaure lies in the cold north — a northern acidified brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. 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.

Shallow throughout (max 4 m), with reeds and vegetation over large areas — water that warms fast in spring.

Permits & rules

Fishing permit required — Mårsomjaure FVOF. Day permit ~100 kr · annual permit ~500 kr.

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

grayling fish
typically ~30 cm · can reach 50 cm
The nutrient-rich water keeps grayling moving constantly between the feeding grounds.
trout salmonids
typically ~35 cm · can reach 70 cm
Trout hunts by feel more than sight in the stained water — short, hard strikes close to the bait.
whitefish whitefish
typically ~30 cm · can reach 55 cm

Fishing Mårsomjaure

perch, pike and grayling sit at the top of the food chain in Mårsomjaure, carried by whitefish and stensimpa. The brown, humic water keeps visibility short — the fishing is more about vibration than sight.

Every session at Mårsomjaure 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

  • Brown, humic water dampens the light — fishing can be good even in the middle of the day.
  • Acidified water yields few, hardy species.
