Iso Lasujärvi

Character of the water

Iso Lasujärvi lies in the cold north — a northern humic brown tarn. The tea-stained, humic water hides the bottom within an arm's length.

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.

Shallow throughout (max 2 m), with reeds and vegetation over large areas — water that warms fast in spring.

Fishing Iso Lasujärvi

perch, pike and zander sit at the top of the food chain in Iso Lasujärvi, carried by roach. The brown, humic water keeps visibility short — the fishing is more about vibration than sight.

Whoever fishes Iso Lasujärvi regularly builds something of their own: a log of what took, where and when. That's how the water gives up its patterns — cast by cast, never all at once.

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.
