Character of the water

Koukkujärvi lies in the cold north — a northern clear oligotrophic forest lake. The water is crystal-clear and the fish skittish in the sharp light. In summer a thermocline settles around 6 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.

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 Koukkujärvi

Koukkujärvi holds 4 species, with perch, pike and trout at the top of the chain and roach schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

Every session at Koukkujärvi 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

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
