Character of the water

Stor-Grundsjön lies in the cold north — a northern humic brown tarn. The tea-stained, humic water hides the bottom within an arm's length.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

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

Fishing permit required — Stor-Grundsjön FVOF. Day permit ~120 kr · annual permit ~600 kr.

  • Trout & Arctic char: protected during the autumn spawn · catch-and-release on certain stretches.

Fishing Stor-Grundsjön

trout sit at the top of the food chain in Stor-Grundsjön. The brown, humic water keeps visibility short — the fishing is more about vibration than sight.

Every session at Stor-Grundsjön 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.
