Character of the water

Grötsjön lies in central Sweden — a humic brown forest lake. The tea-stained, humic water hides the bottom within an arm's length. In summer a thermocline settles around 8 m and splits the lake into two worlds.

The surroundings

The lake lies remote, ringed by forest and bog far from any road. Few find their way here — the water is untouched and the stock undisturbed.

A small but surprisingly deep pocket (13 m) with steep drops straight down from shore — the bottom falls away fast.

  • Pike: keep at most one over 75 cm per day.

Fishing Grötsjön

Grötsjön holds 8 species, with perch, pike and grayling at the top of the chain and elritsa, roach and whitefish schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

Every session at Grötsjön 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.
