Kalvsjön
Character of the water
Kalvsjön lies in central Sweden — a nutrient-rich lowland lake. In summer a thermocline settles around 6 m and splits the lake into two worlds.
The surroundings
The lake lies half-remote, a fair way from the nearest road, tucked into woodland.
Large and deep (23 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

Fishing Kalvsjön
The species list of Kalvsjön runs to 13. The predators — perch, pike and zander — 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 Kalvsjön are alike.
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.
