Character of the water

Stor-Grössjön lies in the cold north — a northern nutrient-rich lowland lake. In summer a thermocline settles around 5 m and splits the lake into two worlds.

The surroundings

The lake lies remote, ringed by forest and bog far from any road. Few find their way here — the water is untouched and the stock undisturbed.

Moderately deep (10 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Stor-Grössjön

The species list of Stor-Grössjön 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.

The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Stor-Grössjön are alike.

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.
