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

• Overview

  Ontario holds Blockville Lake, in Thunder Bay District. The country here is taiga. Roughly 66 hectares: a morning covers one end, an afternoon the other. You are looking at roughly 5.2 km of shoreline, with plenty of water between access points. Longlac at 78 km is the nearest place to stop. Geraldton follows at 89 km, then Greenstone at 95 km. It lies deep inside the county rather than near an edge.

• Where to Fish on Blockville Lake

  Without a survey to go on, judge depth from how the bank falls away. Still water like this holds fish on the edges rather than out in the open. A natural lake fishes on cover, and cover here means weed and timber. Records held for Thunder Bay District cover cisco, blackfin cisco and rainbow smelt. Species recorded across the county may be limited to a few waters. Blockville Lake gives up its fish to patience rather than distance.

• Seasonal Patterns

  Typical July readings run about 16°C; by January the average is down near -20°C. Little of the calendar is open water, so timing counts for everything. The lid arrives early and lasts until roughly early May. Expect the water usable from around early May until roughly mid November. Right after break-up, and again as the nights sharpen, is when to go. Expect Blockville Lake to follow that timing.

• Tackle & Baits

  The access position is unclear from public sources. This is a natural basin, not a dammed one. Mapping shows an empty shoreline: no ramp, no jetty, no marked entry. A light spinning outfit with a small box of lures and some bait covers most of what swims here. A phone call first saves an afternoon. A polite question at the farm gate opens more banks than anything else. Merkley Lake, 2.3 km away, makes the obvious fallback. Check the position at Blockville Lake before loading the car.
