Character of the water

Ivösjön lies in the south — a southern clear oligotrophic deep lake. In summer a thermocline settles around 18 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 (51 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.
