Character of the water

Mosjön lies in the cold north — a northern acidified forest lake. The water is crystal-clear and the fish skittish in the sharp light. In summer a thermocline settles around 6 m and splits the lake into two worlds. Acidification has thinned life down to the hardiest few.

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.

Moderately deep (9 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Mosjön FVOF. Day permit ~100 kr · annual permit ~500 kr.

  • Handheld tackle only. Respect the protected zones at the inlets and outlets.

Species in Mosjön

whitefish whitefish

Whitefish holds in the open water column where light and temperature set the day.

Fishing Mosjön

perch sit at the top of the food chain in Mosjön, carried by whitefish. The clearer water makes the fish wary — and rewards a careful presentation.

Every session at Mosjön 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.
  • Acidified water yields few, hardy species.
