Character of the water

Stor-Grundsjön lies in the cold north — a northern humic brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. In summer a thermocline settles around 7 m and splits the lake into two worlds.

The surroundings

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

Moderately deep (10 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Stor-Grundsjön

Stor-Grundsjön holds 10 species, with perch, pike and grayling at the top of the chain and ål, elritsa and roach schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

Whoever fishes Stor-Grundsjön 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.
