Character of the water

Kallsjön lies in the cold north — a northern clear oligotrophic deep lake. The water is crystal-clear and the fish skittish in the sharp light.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

Large and deep (134 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

  • Pike: keep at most one over 75 cm per day.

Fishing Kallsjön

The species list of Kallsjön runs to 8. The predators — perch, pike and grayling — hunt where the baitfish gather, and on a water this size every bay becomes its own fishery.

Whoever fishes Kallsjön 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

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
  • In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
