Character of the water

Kottlasjön lies in central Sweden — a nutrient-rich lowland lake.

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 — Kottlasjön FVOF. Day permit ~140 kr · annual permit ~700 kr.

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

Fishing Kottlasjön

The species list of Kottlasjön runs to 5. The predators — perch — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

Every session at Kottlasjön 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

  • Nutrient-rich lakes hold plenty of baitfish but often murky water.
