Buttjärnen

Character of the water

Buttjärnen 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 12 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 (32 m) with steep drops straight down from shore — the bottom falls away fast.

Permits & rules

Fishing permit required — Buttjärnen FVOF. Day permit ~60 kr · annual permit ~300 kr.

• Pike: keep at most one over 75 cm per day.
• Trout & Arctic char: protected during the autumn spawn · catch-and-release on certain stretches.
• Handheld tackle only. Respect the protected zones at the inlets and outlets.

Fishing Buttjärnen

perch, pike and trout sit at the top of the food chain in Buttjärnen, carried by roach and vendace. The clearer water makes the fish wary — and rewards a careful presentation.

Every session at Buttjärnen 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.
