Character of the water

Sandviksträsket 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 sits close to town with a road right up to it — easy to reach, but hard-fished and exposed to nutrient runoff from the buildings and fields all around.

Shallow throughout (max 3 m), with reeds and vegetation over large areas — water that warms fast in spring.

Permits & rules

Fishing permit required — Sandviksträsket 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.

Species in Sandviksträsket

typically ~22 cm · can reach 45 cm
The nutrient-rich water keeps perch moving constantly between the feeding grounds.

Pike hunts by feel more than sight in the stained water — short, hard strikes close to the bait.
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.

Fishing Sandviksträsket

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

Whoever fishes Sandviksträsket 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

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