Iso Luoptijärvi

Character of the water

Iso Luoptijärvi lies in the cold north — a northern acidified forest lake. The water is crystal-clear and the fish skittish in the sharp light. In summer a thermocline settles around 7 m and splits the lake into two worlds. Acidification has thinned life down to the hardiest few.

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 (17 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing Iso Luoptijärvi

The species list of Iso Luoptijärvi runs to 2. The predators — perch and pike — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

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 Luoptijärvi are alike.

General rules of thumb for this kind of water

• Clear water makes fish light-shy — dawn, dusk and night are usually best.
• In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
• Acidified water yields few, hardy species.
