Character of the water

Iso Haukijärvi lies in the cold north — a northern mesotrophic stratified lake. In summer a thermocline settles around 9 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 (16 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing Iso Haukijärvi

perch, pike and zander sit at the top of the food chain in Iso Haukijärvi, carried by roach and ruffe. The clearer water makes the fish wary — and rewards a careful presentation.

Every session at Iso Haukijärvi 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

Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
