Character of the water

Karlsvattnet lies in the cold north — a northern nutrient-rich lowland lake.

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.

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 — Karlsvattnet FVOF. Day permit ~60 kr · annual permit ~300 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 Karlsvattnet

perch predatory fish
typically ~22 cm · can reach 45 cm

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

Ruffe works the bottom in the dark — smell and feel come before everything else.
burbot bottom fish
typically ~45 cm · can reach 90 cm
Down on the bottom burbot sifts the soft ground — patience beats speed here.
roach coarse fish
typically ~18 cm · can reach 32 cm
The nutrient-rich water keeps roach 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.
regnbåge fish
typically ~35 cm · can reach 70 cm

Fishing Karlsvattnet

Karlsvattnet holds 7 species, with perch, pike and burbot at the top of the chain and ruffe, roach and regnbåge schooling beneath them. The depth gives the water two storeys — and the fish move between them with the season.

Every session at Karlsvattnet 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

  • Nutrient-rich lakes hold plenty of baitfish but often murky water.
