Character of the water
Östersjön lies in the south — a southern nutrient-rich lowland lake.
The surroundings
The lake lies half-remote, a fair way from the nearest road, tucked into woodland.
Large and deep (25 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

Fishing Östersjön
perch, pike and burbot sit at the top of the food chain in Östersjön, carried by ål, björkna and bream. The nutrient-rich water means plenty of baitfish — and predators that grow fat on them.
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 Östersjön 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.
- Nutrient-rich lakes hold plenty of baitfish but often murky water.
