Grubbsjön

Character of the water

Grubbsjön lies in the cold north — a northern nutrient-rich lowland lake. In summer a thermocline settles around 9 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 (21 m) with steep drops straight down from shore — the bottom falls away fast.

Fishing Grubbsjön

The species list of Grubbsjön runs to 7. The predators — perch, pike and zander — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

Whoever fishes Grubbsjön regularly builds something of their own: a log of what took, where and when. That's how the water gives up its patterns — cast by cast, never all at once.

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.
