Grätnässjön

Character of the water

Grätnässjön lies in the cold north — a northern nutrient-rich lowland lake. In summer a thermocline settles around 6 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.

Large and deep (30 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

Fishing Grätnässjön

The species list of Grätnässjön runs to 10. The predators — perch, pike and grayling — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

Every session at Grätnässjön 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

• Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
• Nutrient-rich lakes hold plenty of baitfish but often murky water.
