Character of the water

Iso Mustajärvi lies in the cold north — a northern clear oligotrophic forest lake. The water is crystal-clear and the fish skittish in the sharp light.

The surroundings

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

Moderately deep (5 m) — shallow bays, the odd reef and a deeper channel through the middle.

Fishing Iso Mustajärvi

Iso Mustajärvi holds 3 species, with perch and pike at the top of the chain and roach schooling beneath them. The modest depth keeps most of the fishing within reach of the bank.

The fishing here follows the water's own rhythm: dawn and dusk have their windows, fronts close and open them, and the season moves the fish. No two sessions at Iso Mustajärvi are alike.

General rules of thumb for this kind of water

  • Clear water makes fish light-shy — dawn, dusk and night are usually best.
