Grassy Lake in Thunder Bay District: How and When to Fish It

• Overview

  Grassy Lake is listed under Thunder Bay District, Ontario. The surface lies 206 metres up. The water measures roughly 6 hectares, so nothing here is far from anything else. On size it sits at the modest end of our Thunder Bay District list. Amethyst Harbour sits 23 km from here and is the nearest stop. After that come Shuniah Township at 30 km and Current River at 31 km. It lies deep inside the county rather than near an edge.

• Where to Fish on Grassy Lake

  We hold no survey for this water; read the slope of the shoreline instead. Read the surface for the wind lane, then fish the edge of it. Bays and points beat straight shoreline every time on water like this. Fish documented in Thunder Bay District include cisco, blackfin cisco, rainbow smelt and bloater. Take it as the county picture rather than a promise for this water. On Grassy Lake the obvious spot is not always the productive one.

• Seasonal Patterns

  Typical July readings run about 17°C; by January the average is down near -13°C. Winter shuts the surface down for months. Firm cover through the cold months, then open water from late April. Average temperatures cross freezing around late April in spring and again near late November in autumn. Fish feed hardest at the start and the close of the open season. The season on Grassy Lake follows the weather closely.

• Tackle & Baits

  Whether you may fish here is not something records settle. You will be walking about 760 m from the nearest car park. Keep the gear simple: light line, small hooks, split shot and a couple of proven lures. Where the road in crosses private land, ask first. A polite question at the farm gate opens more banks than anything else. Ravine Lake at 0.8 km is the sensible second choice. Confirm before you fish Grassy Lake.
