Grunnasjön

Character of the water

Grunnasjön lies in the south — a southern 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 (8 m) — shallow bays, the odd reef and a deeper channel through the middle.

Permits & rules

Fishing permit required — Grunnasjön FVOF. Day permit ~140 kr · annual permit ~700 kr.

Fishing Grunnasjön

The species list of Grunnasjön runs to 9. The predators — perch, pike and salmon — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

Every session at Grunnasjön 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.
