Character of the water

Stora Härsjön lies in the south — a southern acidified forest lake. Acidification has thinned life down to the hardiest few.

The surroundings

The lake lies half-remote, a fair way from the nearest road, tucked into woodland.

Large and deep (42 m): a central basin ringed by drop-offs and shallow bays around the edges — varied bottom with many spots to read.

  • Pike: keep at most one over 75 cm per day.

Fishing Stora Härsjön

The species list of Stora Härsjön runs to 9. The predators — perch, pike and trout — hunt where the baitfish gather, and on a water this size you soon learn where it holds its fish.

Whoever fishes Stora Härsjön 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

  • In deep, oxygenated lakes the predators seek cool depth in summer, shallower in spring and autumn.
  • Acidified water yields few, hardy species.
  • Nutrient-rich lakes hold plenty of baitfish but often murky water.
