Character of the water

Hattjärnen lies in central Sweden — a mesotrophic stratified lake. In summer a thermocline settles around 8 m and splits the lake into two worlds.

The surroundings

The lake sits close to town with a road right up to it — easy to reach, but hard-fished and exposed to nutrient runoff from the buildings and fields all around.

A small but surprisingly deep pocket (14 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing Hattjärnen

Hattjärnen holds 7 species, with perch, pike and zander at the top of the chain and roach, ruffe and vendace schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

Every session at Hattjärnen 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.
