Fishing Flensjön
The species list of Flensjön runs to 6. The predators — perch and pike — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.
Every session at Flensjön 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.
