Iso Kuolpajärvi

Character of the water

Iso Kuolpajärvi lies in the cold north — a northern mesotrophic stratified lake. In summer a thermocline settles around 8 m and splits the lake into two worlds.

The surroundings

The lake sits close to town with a road right up to it — easy to reach, but hard-fished and exposed to nutrient runoff from the buildings and fields all around.

A small but surprisingly deep pocket (15 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing Iso Kuolpajärvi

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

The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Iso Kuolpajärvi are alike.

General rules of thumb for this kind of water

• In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
