Greenwater Lake Fishing near Longlac, Ontario

• Overview

  You will find Greenwater Lake in Thunder Bay District, Ontario. Everything around it is spruce and muskeg. Roughly 22 hectares: a morning covers one end, an afternoon the other. With about 2.1 km of edge, you can try several depths in one session. Some 29 km away sits Longlac, the nearest settlement. Beyond it, Geraldton at 34 km and Greenstone at 47 km. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Greenwater Lake

  Nothing we hold settles how deep this runs. Where the bottom changes texture, fish gather; find that line. Still water like this holds fish on the edges rather than out in the open. Survey and observation records for Thunder Bay District include cisco, blackfin cisco and rainbow smelt. County data is a starting point rather than a guarantee. Anyone new to Greenwater Lake should walk it once before setting up.

• Seasonal Patterns

  Expect July near 16°C and January near -18°C on the long-run figures. The ice season is long here and the open one short. Expect a solid lid for months and a thaw around early May. From about early May to around mid November, expect open water on the long-run figures. The strong weeks are the first after break-up and the last before the freeze. That shapes the year on Greenwater Lake.

• Tackle & Baits

  No access rule appears in what we hold. No dam controls it, and the level follows the season. Formal access is not mapped, so the last stretch is likely on foot. A light spinning outfit with a small box of lures and some bait covers most of what swims here. Local rules can differ across the county line, so check where you stand. Some ground is open by custom rather than by right, so tread carefully. Twomey Lake at 1 km is the sensible second choice. Signs at Greenwater Lake carry more weight than any list.
