Character of the water

Grundvattnet lies in the south — a southern 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 — Grundvattnet FVOF. Day permit ~100 kr · annual permit ~500 kr.

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

Fishing Grundvattnet

Grundvattnet holds 1 species, with perch at the top of the chain. The modest depth keeps most of the fishing within reach of the bank.

Every session at Grundvattnet 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.
