Character of the water
Kalven lies in the south — a southern nutrient-rich lowland lake.
The surroundings
The lake lies remote, ringed by forest and bog far from any road. Few find their way here — the water is untouched and the stock undisturbed.
Moderately deep (6 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Kalven
perch, pike and zander sit at the top of the food chain in Kalven, carried by björkna, bream and ruffe. 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 Kalven are alike.
General rules of thumb for this kind of water
- Nutrient-rich lakes hold plenty of baitfish but often murky water.
