Character of the water

Blecks-Rottjärnen lies in central Sweden — a clear oligotrophic deep lake. The water is crystal-clear and the fish skittish in the sharp light. In summer a thermocline settles around 10 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.

A small but surprisingly deep pocket (28 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing Blecks-Rottjärnen

The species list of Blecks-Rottjärnen runs to 3. The predators — perch and pike — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

Every session at Blecks-Rottjärnen is fished in whatever conditions hold right then — the same pressure, wind and light as over the real water. What bites today isn't what bit the day before, and those who return learn the water for real.

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.
