Character of the water

Idsjön lies in central Sweden — a clear oligotrophic forest lake. The water is crystal-clear and the fish skittish in the sharp light. In summer a thermocline settles around 7 m and splits the lake into two worlds.

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 (7 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Idsjön

The species list of Idsjön runs to 15. 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.

Every session at Idsjön 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.
