Character of the water

Grönvalltjärnen lies in the cold north — a northern mesotrophic stratified 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 (9 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing permit required — Grönvalltjärnen FVOF. Day permit ~140 kr · annual permit ~700 kr.

Pike: keep at most one over 75 cm per day.
Handheld tackle only. Respect the protected zones at the inlets and outlets.

Species in Grönvalltjärnen

typically ~62 cm · can reach 120 cm

Pike is a sight-hunter here — the clear water means long follows before the take.

roach coarse fish

Here roach lives on the small stuff — and rewards those who fish small and fine.

ruffe perch family

Fishing Grönvalltjärnen

Grönvalltjärnen holds 4 species, with perch and pike at the top of the chain and roach and ruffe schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

Every session at Grönvalltjärnen 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

Stratified, oxygen-poor lakes push the fish up above the thermocline in summer.
