Character of the water

Stortjärnen lies in central Sweden — a nutrient-rich lowland lake. In summer a thermocline settles around 4 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.

Moderately deep (12 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Stortjärnen

perch, pike and zander sit at the top of the food chain in Stortjärnen, carried by bream, ruffe and id. The nutrient-rich water means plenty of baitfish — and predators that grow fat on them.

Whoever fishes Stortjärnen 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

Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
Nutrient-rich lakes hold plenty of baitfish but often murky water.
